Prepared Remarks:

Operator

Good day, ladies and gentlemen. And welcome to the Kratos Defense & Security Solutions fourth-quarter 2018 earnings conference call. [Operator instructions] As a reminder, today's conference may be recorded. I would now like to turn the call over to Marie Mendoza, senior VP and general counsel.

Ma'am, please begin.

Marie Mendoza -- Senior Vice President and General Counsel

Thank you. Good afternoon, everyone, and thank you for joining us for the Kratos Defense & Security Solutions fourth-quarter 2018 conference call. With me today is Eric DeMarco, Kratos' president and chief executive officer, and Deanna Lund, Kratos' executive vice president and chief financial officer. Before we begin the substance of today's call, I'd like everyone to please take note of the safe harbor paragraph that is included at the end of today's press release.

This paragraph emphasizes the major uncertainties and risks inherent in the forward-looking statements we will make this afternoon. Please keep these uncertainties and risks in mind as we discuss future strategic initiatives, potential market opportunities, operational outlook, and financial guidance during today's call. Today's call will also include a discussion of non-GAAP financial measures as that term is defined in Regulation G. Non-GAAP financial measures should not be considered in isolation from or as a substitute for financial information presented in compliance with GAAP.

Accordingly, at the end of today's press release we have provided a reconciliation of these non-GAAP financial measures to the company's financial results prepared in accordance with GAAP. With that, I will now turn the call over to Eric DeMarco.

Eric DeMarco -- President and Chief Executive Officer

Great. Thank you, Marie. For Q4 in 2018 the organic growth trajectory of Kratos continued, and we generated our company's best operating and financial performance in many years, substantially exceeding our EBITDA, gross margin, operating income, and EPS objectives, including positive GAAP EPS in the fourth quarter. As we begin the new year, we are forecasting continued organic growth, including organic revenue growth of approximately 12.5% and adjusted EBITDA organic growth of approximately 15% for 2019 over 2018, and this excludes all of the following: it excludes the impact of the FTT acquisition we announced today; it excludes the impact of any potential tactical UAS production revenues we could generate; and it excludes the impact of the potential upside from certain very large, hypersonic system and ballistic missile target opportunities we are pursuing, which are expected to be awarded this year.

Supporting our future organic growth expectations, Kratos' Q4 book-to-bill ratio came it at 1.3 to 1, and our last six months' book-to-bill ratio was 1.4 to 1, with every Kratos business unit generating between a 1.1 to 1.4 book-to-bill ratio for Fiscal '18. Overall, our bookings increased $254 million or approximately 55% for 2018 over 2017, and bookings for classified work were up significantly year over year. Additionally, even with these substantial 2018 bookings, our bip pipeline continues to increase. It's now at $6.8 billion at the end of 2018, and this reflects our alignment with the DoD's national security strategy and its funding priorities.

At December 30, 2018, our Unmanned Systems division generated organic growth of 75% over the previous 24 months, and we are forecasting our target drone business to grow to approximately $250 million in annual revenue over the next few years or 90% organic growth over the 2018 revenues. In our tactical drone business, we now have six customer-funded tactical drone programs, with several additional programs expected to be under contract by the end of this year. The momentum in Kratos' tactical drone business continues to build. And based on very recent customer meetings, we are more confident than ever that it is not a question of if, but rather when this business will be an explosive growth generator for our company.

We also believe that the when is rapidly approaching and we expect our tactical drone business to ultimately be substantially larger than our target drone business as we achieve production. We continue to see 2019 as the year of bookings for our tactical business, with significant growth and financial contribution expected to begin in 2020. We also see 2019 as the year that Kratos is established as the world leader in the high-performance unmanned aerial drone system product class that we're in, which we see as a multi-billion-dollar opportunity for our company. From a specific program update standpoint, in late December 2018 the Air Force publicly announced that Kratos' XQ-58A VALKYRIE is scheduled to fly in calendar Q1 of 2019, which means in the next 30 days.

Once the successful series of VALKYRIE flights occurs, which will be one of the most significant milestones in Kratos' history, we expect to receive initial unit orders for the Valkyrie. Based on recent customer meetings and discussions, which have been extremely favorable, we expect this to occur in 2019. Program F is scheduled for additional customer-funded demonstration flights in Q2 of this year and we expect initial unit orders later on in 2019 or early next year. The DARPA-funded Gremlins program, with our prime partner Dynetics, has planned initial demonstration flights scheduled for Q2 of this year.

And once the Gremlins demonstrations are successfully completed, we expect initial orders later in 2019 or in 2020. On our confidential Thanatos program, which we were informed by our customer that we were successful on late last year, work on the new and expanded secure production facility is beginning, and we have executed the lease on the new facility I previously mentioned on the last call. We expected Thanatos to be a meaningful financial contributor beginning in 2020. We recently announced Kratos' AETHON ISR UAS, which is flying today.

It is now under a funded development contract with a government agency for several millions of dollars, with this program expected to be a meaningful contributor to Kratos in 2020. Project Spartan continues to gain traction. We currently expect to be under initial contract in Q3 of 2019, with this program expected to be a meaningful financial contributor to Kratos beginning in 2020. We have a new project we can now discuss with you.

It's called APOLLO, which we expect to be under contract by Q3/Q4 of this year and which is expected to be financially meaningful to Kratos in 2020. Kratos' DIU MAKO UAS program was delayed from a previously expected Q4 2018 funding date, to now an expected Q2 2019 funding date, with this delay being indicated in a public announcement by the customer in December. The delay in the DIU MAKO funding was one of the primary reasons why our Q4 revenues came in below forecast, but this program now expected to be financially meaningful to Kratos beginning in 2020. Also importantly, we now have a third customer for Kratos' MAKO, with this initiative named ATHENA, and we are looking for a contract award from this customer in the second half of 2019.

We also continue to work on Project A and Project Z and are looking for initial development contract awards in 2020. Just a few weeks ago, the first high-performance Kratos drone came off our Oklahoma facility's manufacturing line with production quantities expected to increase throughout 2019 and a significant step-up in production expected in 2020 related primarily to Kratos' tactical programs. For 2019, we expect primary growth drivers in our Unmanned Systems business will be from our target drone business, including under-contract programs with the U.S. Air Force, U.S.

Navy, U.S. Army, and other agencies and also from a very large multiyear international award we received in late 2018. In 2019, we expect to continue ramping on the Air Force AVSAT program full-rate production Year 14 with full-rate production Years 15 and 16, which represent production and deliveries for Fiscal Years 2020-2021 and 2021-2022 expected to be formally authorized in 2019. This program is sole-sourced to Kratos.

In 2019, we expect continued execution on Kratos' five-year $93 million contract for target drones with the U.S. Army that we received last year. Our most recent information from the customer indicates this program will begin ramping in late 2019 and into 2020 and also into '21. This program is sole-sourced to Kratos.

We are also in production with a confidential customer with execution expected to continue increasing in the second half of this year and into 2020 as we head into future full-rate production. This program is also sole-sourced to Kratos. In July of 2018, the U.S. Navy announced the expected sole-source award to Kratos of SSAT program Low-Rate Initial Production Year 3 or LRIP 3 for up to 60 BQM177 target drones.

This award was originally expected in late 2018. We are currently negotiating LRIP 3 with the customer, which now has an expected Q2 2019 award date with forecast LRIP 3 quantities now at approximately 50 drones. We have reflected this new anticipated schedule and revised quantity in our 2019 guidance. Our SSAT customer has also recently indicated the award of a multiyear sole-source full-rate production contract to Kratos at increased quantities, and this is expected to be pulled to the left and accelerated with an expected award date either late this year or early in 2020.

And if this happens, this will favorably impact Kratos in 2021 and 2022. And directly related to the SSAT program and our financial forecast, just yesterday NAVAIR publicly announced that Kratos' BQM177A has achieved initial operating capability or IOC, which is an extremely important milestone and further solidifies our expectation for SSAT to ultimately be a $1 billion-plus program to Kratos. As I mentioned, in late 2018, we announced a large new sole-source multiyear international target drone contract award with the potential value of up to approximately $100 million, which we expect to begin contributing to us in 2019. However, on this and other Kratos international target drone programs, the temporary U.S.

federal government shutdown caused delays in certain export license-related approvals which are required for Kratos to ship drones out of the United States, which situation was also recently reported as having an impact on the industry by the Wall Street Journal. This delay in export licenses is also impacting Kratos' satellite business. Accordingly, in our 2019 financial guidance we have taken a cautious approach and we have moved to late '19 certain international program-related execution or deliveries we had previously expected for the first quarter and the first half of 2019 as the government works through its backlog of export license approvals. Kratos' Satellite Communications, Cyber and Training division, our company's largest and most profitable, had a very solid 2018 and a particularly strong second half of the year, including Q4, which trajectory is historically typical for this business and which we are forecasting for 2019.

This business also had very strong 2018 bookings, including bookings in the second half of the year of nearly $250 million or 1.5 to 1 book-to-bill ratio. Additionally, our satellite business has had a number of positive developments since we last reported to you, including that we now expect to be successfully designed in or selected for a number of new space opportunities, many of which are classified, which when the related Kratos products and solutions reach production and delivery, beginning approximately 18 months from now, we expect a significant new growth curve to begin for this business. National security-related spending in the space and satellite area are seeing some of the largest DoD funding increases. These are driven primarily by the perceived Russian and Chinese threat to our country's space assets, which is providing Kratos a number of large new opportunities.

Also, there are thousands of new LEO, GEO, and MEO satellites planned for over the next several years, with it recently being reported that an estimated 3,300 new satellites are expected to be launched through 2027, representing a potential market opportunity of $284 billion. Of this market opportunity, we believe that approximately 70% of a space system's life cycle costs are associated with the ground solutions, and ground solutions is where Kratos is a clear industry leader as represented by our ground equipment, services, and solutions, which support approximately 85% of U.S. space missions and which are used by approximately 75% of all global satellite operators. Related to this forecast market growth, recent publicly announced developments on the ground, which are clearly aligned with Kratos' satellite and space business, include the introduction of Cloud-based technology architectures from companies including Amazon, which will be offering ground stations-as-a-service under the name of AWS Ground Station.

Additionally, Google parent, Alphabet, Inc., has an initiative called Loon, which is offering cell tower connectivity using balloons that fly on the edge of space. And there are a number of HAPS, or high-altitude pseudo satellite drone initiatives under way. Each of these represents new opportunities for Kratos' industry-leading ground-based satellite and space business. Also, as you know, Kratos owns and operates what we believe is the largest commercial network of space-focused radio frequency sensors, which is used to identify, locate, and mitigate interference or other unwanted issues with space signals.

Kratos' ground network consists of several hundred sensors at approximately 20 locations around the globe and is one of our company's fastest growing and most valuable businesses and assets. Kratos' spectrum monitoring business is expected to continue to organically grow for the foreseeable future, driven primarily by the thousands of additional satellites expected to be launched in the next few years and our government customer demand. Kratos' training systems business also had a very solid 2018 and we are forecasting an even stronger 2019, driven by the major long-term programs we have successfully received, including KC-46, Marine Corp Common Aircrew Trainer, CH-53, AVET, NATS, and RSN. Kratos' training systems business has one of the largest bid and proposal pipelines in our company, which includes several large multiyear programs we are pursuing, which is directly related to the significant funding increases in the DoD budget for weapon systems, upgrades, and operational readiness.

Kratos' rocket support services, or our RSS, business, continues to be an industry leader in the rapid development, demonstration and fielding of high-performance, technology-leading ballistic missile target and hypersonic systems, areas which are also seeing significantly increased DoD funding and growth. Emphasizing this growth opportunity, since we last reported to you, the president has announced a new missile defense policy aimed to address the proliferation by peer, near peer, and rogue adversary advances in ballistic and hypersonic missile systems. Representative of the mission-critical U.S. national security priorities that Kratos' RSS business supports, the U.S.

Navy recently publicly stated that the next-generation air missile defense radar, or AMDR system, had successfully performed in 14 ballistic missile tests with additional tests planned. Though I cannot get into specifics for security reasons, Kratos' RSS BMD target systems are an important element of this test regimen and we recently announced that a Kratos RSS target system successfully exercised the AMDR system. 2019 is currently forecast to be very strong for RSS with Q3 and Q4 expected to be particularly strong based on current expected mission and execution requirements in new contract awards. Additionally, our ballistic missile targets and hypersonic systems business is currently pursuing a number of new, large program opportunities, which if we are successful in 2019 award schedules hold could provide significant upside to our 2019 financial forecast and position this business for further substantial growth in 2020.

Our C5ISR modular systems business had a strong second half of 2018, including the fourth quarter, and we are executing on a number of Unmanned Aerial System, missile defense, radar and other C5ISR and CBRNE system opportunities. This business has firmed up over the past several quarters, primarily the result of the recapitalization of strategic weapon systems by the U.S. and our allies, and the related procurement of missile, missile defense, radar, unmanned drone, and other systems which Kratos supports. Based on our C5ISR business' current backlog and the opportunity pipeline, in 2019, we're anticipating moderate organic growth, with quarterly performance -- quarterly financial performance expected to be driven primarily by our respective customers' production and execution and delivery schedules.

Major representative programs our C5ISR business supports include Patriot, FAAD, LCS, CPP, SHORAD, and certain Unmanned Aerial System programs. Our microelectronics business performed as expected in 2018, with the second half of the year being the strongest and with this business full year book-to-bill ratio being approximately 1.1 to 1. We are forecasting moderate organic growth for this business in 2019, including an anticipated strong second half of 2019 based on delivery and execution schedules from our current near-record backlog. Q1 is being forecast as, by far, the lowest for this business, with the business ramping from there.

Representative programs our microwave business support include F-15, F-16, Iron Dome, Sling of David, BARAK, SPYDER, ARROW, and Gripen. For Kratos' traditional Government Services business, the good news is that in the second half of 2018 we were awarded two new large contracts supporting a directed-energy laser program and a radar program. However, each of these new programs is currently ramping far slower than we anticipated. This delay in ramp is also a primary driver that caused Q4 revenues to come in below our forecast.

We are working with the respective customers to address the delays and we expect these to be back on track by the second half of 2019. In the full year and Q1 2019 financial guidance, Deanna will be going through with you. In addition to the business considerations that I previously mentioned, we are including no initial tactical UAS production in our 2019 forecast and we are not including certain very large new program opportunities we are pursuing, including in the missile defense and hypersonic areas as the outcome of these are very binary, and if we are successful, these could meaningfully positively impact our 2019 forecast. Additionally, as a result of the change in control of the House of Representatives and the resulting immediate partial U.S.

federal government shutdown, in our initial 2019 financial forecast, we are providing a cautious outlook and we are assuming a federal Fiscal Budget 2020 Continuing Resolution will begin on October 1st of this year and it will last throughout the rest of the year to 12/31/19. This assumption means planned customer production increases on certain Kratos under-contract target drone programs will not be realized in Calendar '19 but we are forecasting them for Calendar 2020 once the federal Fiscal 2020 budget is assumed authorized. Deanna?

Deanna Lund -- Executive Vice President and Chief Financial Officer

Thank you, Eric. Good afternoon. Kratos' fourth-quarter 2018 revenues of $164.4 million, which were up sequentially from third quarter '18 revenues of $159.4 million, came in below our expectations of $182 million to $192 million. Our revenue coming in below our expectations was primarily related to five programs, four of which Kratos has now successfully received, which were awarded either later in the fourth quarter than we forecast or which have not ramped as quickly as we forecast, and our DIU program, which Eric mentioned earlier, with the new contract award now expected in Q2 of '19 due to the recent changes in DIU organizational leadership.

The good news is that four of these are now under contract with Kratos. We are working closely with our customers to ramp them up, including the hiring of highly cleared personnel on two new UAS programs, and we are forecasting that each of these contracts will back on the planned run rate by the middle of 2019, which is reflected in our 2019 guidance. Compared to the fourth quarter of '17, revenues decreased slightly, by $1.9 million, from $166.3 million, primarily due to the continued reduction in our legacy Government Services revenues as well as the timing of production and shipment ramps in the fourth quarter of '17 compared to '18, primarily on our AFSAT program in the Unmanned Systems division. Our adjusted EBITDA came in at $18 million above our expectation of $13 million to $17 million, primarily driven by a favorable mix of revenues and the positive benefit of cost reduction actions we have taken throughout 2018 as well as our initiative of enhancing operating margins by foregoing low-margin opportunities or more aggressively negotiating more favorable margin with the potential result of reduced revenues.

Additionally, Kratos' adjusted EPS of $0.09 per share also exceeded our forecast of $0.03 to $0.07 per share for the quarter. In the fourth quarter, KGS generated revenues of $128.2 million, adjusted EBITDA of $15.1 million or 11.8% of revenues, and operating income of $11.6 million, all of which were up from the prior year comparable revenues of $124 million, adjusted EBITDA of $12 million, and an operating loss of $15.8 million or operating income of $8.4 million, excluding the impairment of goodwill, respectively, reflecting the growth primarily in the satellite communications and training systems businesses, a favorable mix of revenue as well as margin improvement in our modular systems business. From an accounting standpoint, Kratos was required to adopt a new revenue recognition practice beginning January 1st of this year of 2018, which can affect the timing of revenue recognition for certain contracts. The impact of this new accounting standard was approximately $9.4 million and $29.9 million on Kratos' fourth and full year -- fourth-quarter and full-year 2018 revenues, respectively.

Our Q4 operating income was $10.8 million or 6.6%, up from the fourth quarter of '17, with an operating loss of $15 million, which included the impairment of goodwill in our DRSS or legacy Government Services business of $24.2 million. Excluding the impairment of goodwill in 2017, operating income was $9.2 million, or 5.5% of revenues. The increase was driven by a reduction of SG&A expenses, reflecting the impact of the cost reduction actions we have taken as well as the reduction of discretionary R&D expenses. Our adjusted EBITDA for the fourth quarter is from continuing operations and excludes noncash stock compensation costs of $2.1 million and severance-related cost of $400,000.

On a GAAP basis, net income for the fourth quarter was $4.7 million, which includes the loss from discontinued operations of $500,000 and includes a tax provision of $200,000, primarily reflecting tax expense for foreign jurisdictions and for states for which we cannot utilize our NOLs. Moving on to the balance sheet and liquidity, our cash balance was $182.7 million plus $300,000 of restricted cash at December 30th. At quarter end, we had zero amounts outstanding on our bank line of credit and $9.7 million of letters of credit outstanding. Debt outstanding was $294.2 million at quarter end and net debt was $111.5 million.

Out LTM adjusted EBITDA was $60.5 million with a net leverage ratio of 1.84 to 1. On a pro forma basis for the FTT acquisition, which was announced earlier today, net leverage is approximately $2 million -- 2.0. The cash consideration portion of $33 million, which is subject to working capital-related adjustments, consists of approximately $19 million paid at close, with the balance payable over three years. Cash flow generated from continuing operations for the fourth quarter was $2.7 million, which includes the use of approximately $400,000 of internal and noncapital expense related to development costs related to the LCASD program.

Capital expenditures were $4.7 million, including approximately $2.3 million related to the Unmanned Systems division, primarily reflecting the two LCASD Kratos-owned aircraft and related equipment that we were building, and we currently expect this capital effort to be complete in the first quarter of '19. Our free cash flow from operations for the quarter was a use of $2 million, reflecting the $2.7 million of cash generated from operations, less the capital expenditures of $4.7 million. Milestone collections primarily on two large training systems and two international target drone programs that were expected in the fourth quarter of '18 are now expected in the first and second quarters of '19 based on our most recent operating plans. This shift in the achievement of these milestone deliverables resulted in an increase of our DSOs from 129 days at the end of the third quarter to 131 days at the end of the fourth quarter.

Our DSOs include long-term delivery projects, where we invoice amounts at the completion of certain milestones and/or final delivery of products. Our contract mix for the quarter was 86% of revenues from firm, fixed-price contracts, 10% on cost-plus contracts, and 4% on time-and-material contracts. Revenues generated from contracts with the U.S. federal government during the quarter were approximately 72%, including revenues generated with the DoD, non-DoD federal government agencies, and FMS contracts, which were approximately 9% in the quarter.

We generated 7% from commercial customers and 21% from foreign customers. Today we are providing first-quarter revenue guidance of $147 million to $157 million, adjusted EBITDA guidance of $9 million to $11 million, and adjusted EPS guidance of zero to $0.02 per share, and full-year revenue guidance of $720 million to $760 million and adjusted EBITDA of $71 million to $77 million. As Eric mentioned earlier, full-year and first-quarter 2019 financial guidance reflects the estimated impact of the recent partial government shutdown that has delayed certain domestic and foreign military sales contract awards and export license approvals required for international sales. The company is providing full-year 2019 cash flow from operations guidance of $40 million to $50 million, capital expenditures of $28 million to $30 million, and free cash flow guidance of $10 million to $20 million plus the expected final cash receipt of the retained working capital of the company's divested PSS business of approximately $4 million to $6 million.

We expect CAPEX to be at elevated levels for 2019 as we make the necessary investments for manufacturing and test equipment for a new Oklahoma and new secured facility that Eric mentioned earlier of approximately $6 million to $8 million, and approximately $4 million to $6 million related to aerial target drones the company plans to build in preparation of fulfilling expected customer requirements. We expect our estimated cash taxes to be approximately $2.5 million to $3.5 million for FY '19 and expect the impact of tax reform to be fairly insignificant to our estimated cash taxes due to our over $300 million of net operating loss provision. Our guidance also reflects the anticipated impact of the FTT acquisition that we announced earlier today. Eric?

Eric DeMarco -- President and Chief Executive Officer

Thank you, Deanna. As Deanna mentioned, today we announced Kratos' acquisition of Florida Turbine Technologies or FTT. This was the first acquisition Kratos has made since 2012. FTT is a technology and products company strategically positioned for the small- to medium-sized affordable turbo fan and turbo jet market, including for high-performance unmanned aerial drones, missiles and weapon systems.

The affordable leading-edge technology that FTT brings to Kratos and to our Unmanned Systems business is truly incredible, with the recently developed FTT engine systems offering thrust and SFC performance improvements that have previously been unobtainable in the low-cost jet engine arena. As you know, the No. 1 cost in most Kratos drone and weapon systems bill of materials is the engine, and affordability is a key differentiator for Kratos' platforms and systems. Accordingly, we are looking for FTT to further Kratos' vertical integration of our drone and weapon systems, increase Kratos' technology, and our performance lead in these systems and also reduce system costs.

Additionally, the projected market for advanced turbo jet and turbo fan engines in this class alone is easily in the many thousands over the next five years, given the projected number of extended-range and low-cost cruise missile systems, and next-generation unmanned weapon systems to be acquired. In Kratos and FTT, we intend to be the leader in this extremely large and growing market space. FTT today is currently under contract on or pursuing 12 specific programs at this time. Finally, beyond traditional turbo jet and turbo fan engines, FTT is also working to develop advanced affordable engines for hypersonic systems in their special programs area [Inaudible] works, that we believe will demonstrate a new class of affordable hypersonic propulsion system.

Importantly, FTT's next-generation engine technology and programs were previously funded by FTT, meaning intellectual property ownership for Kratos. These FTT engine programs and initiatives are now substantially U.S. government agency and customer funded, meaning no significant internally funded Kratos investments should be required. Similar to CEI, which Kratos acquired in 2012 and which has been the core of Kratos' unmanned aerial drone system strategy, and the UAS business we have today, we believe that FTT over the next few years will also be a disruptive and market-transforming business, with incredible growth and value generation expected to be realized for Kratos' shareholders.

FTT will now become Kratos Turbine Technologies, or KTT, a new Kratos division with Stacey Rock, senior Kratos executive and technologist for over 12 years, becoming the KTT president. It is important to note that the FTT founders and all of their employees will be staying with the company. KTT and Kratos' Unmanned Systems division will be organized so that they will work extremely closely together with Stacey and Steve Fendley, our Unmanned Systems division president, both being Auburn engineering graduates. The acquisition of FTT furthers Kratos' position as a unique technology asset or company.

We're disrupting the national security market with affordable leading-technology systems and products. We're in a growth trajectory that looks pretty substantial for the next several years. With that, we'll open the line up for questions. 

Questions and Answers:

Operator

Thank you. [Operator instructions] Our first question comes from the line of Peter Arment of Baird. Your line is now open.

Peter Arment -- Baird -- Analyst

Yes, thanks. Good afternoon, Eric, Deanna.

Eric DeMarco -- President and Chief Executive Officer

Good afternoon.

Peter Arment -- Baird -- Analyst

Eric, just, I guess, to focus on your initial comment about the, well, I guess, the target business growing to $250 million in revenues, I guess, is there a path you see? How many years does that take? I know you said over the next few years, but is it -- are we seeing this all by missile defense testing on existing programs? Or do you see new programs? Maybe just some color there.

Eric DeMarco -- President and Chief Executive Officer

The vast majority, vast majority in these existing programs, and we see ourselves getting there in three or four years at the most.

Peter Arment -- Baird -- Analyst

OK. And just as a follow-up, just if I could just on FTT, you mentioned the 12 programs they're on. Is there programs of record that you can disclose? Or is there any more color on that? Thanks.

Eric DeMarco -- President and Chief Executive Officer

Let me say it this way, and I'm going to say it this way for competitive reasons. If you take a look at weapon systems, a number of them are going to ER or extended range weapon systems. So if you look at existing weapon systems, these are air-to-surface weapon systems, shipborne-to-surface weapon systems, and you'll see the name of the weapon system with a -ER for extended range. That is a good representative example of the existing programs that are being modified for the threat.

Peter Arment -- Baird -- Analyst

Got it. I'll jump back in the queue. Thanks, Eric.

Eric DeMarco -- President and Chief Executive Officer

OK.

Operator

And our next question comes from the line of Ken Herbert of Canaccord. Your line is now open.

Ken Herbert -- Canaccord Genuity -- Analyst

Hi, Eric and Deanna. Good afternoon.

Eric DeMarco -- President and Chief Executive Officer

Good afternoon.

Deanna Lund -- Executive Vice President and Chief Financial Officer

Hi, good afternoon.

Ken Herbert -- Canaccord Genuity -- Analyst

I just wanted to first start out just again on the FTT acquisition, it sounds like if they're successful on some of these that it could potentially require a fairly significant investment to support the production ramp. Can you at all talk about sort of how the CAPEX associated with this business looks? And I know, obviously, that's been a major issue for you over the last few years to capitalize -- to support the ramp. What's the outlook for this business assuming they're successful? And what could the cash implications be around the investments?

Eric DeMarco -- President and Chief Executive Officer

So the outlook for the business is extremely bright. There was a very large and strong demand from government agencies for alternatives and for next-generation turbo jets and turbo fans for their weapon systems. The initial investment that's included in the business plan and our financial forecast is $3 million to $5 million per year. OK? That goes out for a number of years.

If we are successful on some of these programs that we're getting designed in on and they go into production, those numbers will increase, but so will the revenue of the business, the profit of the business and the cash flow. I'm not going to get into details on what that looks like two or three years from now if we get there. Let's take it like we did with our Unmanned Systems division. Let's get designed in, let's win the programs, then I'll walk you through the investment required for the growth.

Ken Herbert -- Canaccord Genuity -- Analyst

OK. That's great, but it sounds like on sort of relative to your tactical business, it's likely a much lower investment profile, it sounds like.

Eric DeMarco -- President and Chief Executive Officer

Far lower, far -- it is nothing like we have done for the past several years on the VALKYRIE and what we did previously on the MAKO. No, sir.

Ken Herbert -- Canaccord Genuity -- Analyst

OK. Great. And if I could, I just wanted to follow up. Obviously, a lot of press this week on the Boeing announcement of their loyal wing man market entrant into international markets.

Can you comment, Eric, on -- I know, obviously, you would always expect and you've had competition in the market, but sort of how you view that relative to your portfolio? And is it something you expect near or midterm to be a potential sort of threat to your United States business? I know obviously that particular aircraft seems to be targeted internationally, but how would you characterize or frame up that?

Eric DeMarco -- President and Chief Executive Officer

Well, as you alluded to, Ken, we always knew competition would come because the market opportunity for jet drones that can perform in anti-access/area denied airspace, it's in the billions. It's coming. We are following the Unmanned Systems strategic roadmap that was initially put out in 2010, and the last 9 years have pretty much tracked to that roadmap. Very candidly, this competitor and it coming from Australia with a significant Australian investment, we don't think it could have worked out better for our company, and let me tell you why.

First of all, our price point. As you know, the price point on our VALKYRIE depending on quantities is $2 million to $3 million, and we have basically proven that out, because as you know we've built three aircraft. All right? Our aircraft has at least published 50% greater range. Our aircraft has internal weapons space, right? We're runway-independent, which is critically important to the U.S.

customers. We're launched off of rail and recovered by a parachute, including in water where we soft seal, and the turnaround time for our drones is incredible, right? Very importantly, our drones exist today and they're flying today. The competitors, they have a model today. They say they'll be flying late next year.

So again as you said, we knew the competition would come but we are very comfortable with our position, and the affordability for the performance is -- we believe it's unmatched and that's from our customers.

Ken Herbert -- Canaccord Genuity -- Analyst

Great. Thank you very much. I'll pass it back there.

And our next question comes from the line of Noah Poponak of Goldman Sachs. Your line is now open.

Noah Poponak -- Goldman Sachs -- Analyst

Is FTT included or excluded from the 2019 guidance?

Deanna Lund -- Executive Vice President and Chief Financial Officer

It is included for the period of the -- from the period of acquisition through the end of the year. So roughly 10 months.

Noah Poponak -- Goldman Sachs -- Analyst

So can you quantify how much revenue is in the $720 million to $760 million from it?

Deanna Lund -- Executive Vice President and Chief Financial Officer

Yes. So it's approximately $45 million.

Noah Poponak -- Goldman Sachs -- Analyst

OK. OK. So that's the number from the release. Got it.

So then the -- that implies, I guess, sort of 12% organic revenue growth in the business. Eric, you made some comments here about changing the growth curve, going forward. Are you saying you expect the growth rate in 2020, 2021 to be higher than 12%?

Eric DeMarco -- President and Chief Executive Officer

Yes.

Noah Poponak -- Goldman Sachs -- Analyst

OK. And then on the margins, the EBITDA guidance implies a relatively flat adjusted EBITDA margin, but you have pretty good growth which should have some drop-through. You're layering in a business with a higher margin than the legacy business. And you're vertically integrating what you just described was a pretty significant cost component.

I would think that would all add up to a decent amount of margin lift.

Eric DeMarco -- President and Chief Executive Officer

Yes. So as we've demonstrated over the last few years and including Q4, we've typically ended up being conservative on our margin guidance. We have routinely achieved it or exceeded it, and we're hopeful to do that again going forward.

Noah Poponak -- Goldman Sachs -- Analyst

OK. Is it possible to quantify how much of your cost of goods sold is the engine? Just wanted to get a little bit -- any kind of way to frame a more precise degree of uplift from that vertical integration. It would be really helpful.

Eric DeMarco -- President and Chief Executive Officer

Yes. It's approximately 30% to 40% of the bill and material costs depending on the drone.

Noah Poponak -- Goldman Sachs -- Analyst

Got it. That's really helpful. Yes. On cash flow, at one point you were pointing to getting to 70% of adjusted EBITDA translating to cash from ops.

For 2019, that would be over $50 million. The guidance is $40 million to $50 million. And you've got what seems like a not insignificant amount of slippage out of 2018. When should we expect the cash flows to convert more to what we're seeing on the P&L?

Deanna Lund -- Executive Vice President and Chief Financial Officer

As I had mentioned earlier on the call, Noah, there's a number of large training programs, which have milestones attached to final delivery. So we don't get to see those final milestones and the retentions until the final delivery, which is some of the slip into '19. However, as we have continued to grow that business at a faster pace than the rest of the business, those milestones will continue to -- as old milestones are achieved, there's new milestones that we need to achieve for final collection so we will collect those amounts that we expected from '18. But new milestones will then need to be achieved in '19 and '20 for those new training systems that we are building and then ultimately delivering in 2020 and 2021 because some of these programs span a period of performance over two years.

Noah Poponak -- Goldman Sachs -- Analyst

I see. I guess I would have thought you kind of knew that when you were targeting 70% of adjusted EBITDA. Does that fundamentally change that target for the time being?

Deanna Lund -- Executive Vice President and Chief Financial Officer

Yes, due to the mix of the business that we're seeing in that -- especially on that training side. And then also in our drone business as well because the milestones are similarly weighted in the drone business.

Ken Herbert -- Canaccord Genuity -- Analyst

I see. OK. Thanks so much.

And our next question comes from the line of Josh Sullivan of Seaport Global. Your line is now open.

Josh Sullivan -- Seaport Global -- Analyst

Hey, good evening.

Eric DeMarco -- President and Chief Executive Officer

Hi, Josh.

Josh Sullivan -- Seaport Global -- Analyst

Just for FTT, it looks like they won a $50 million, what, ATA contract in December. Can you just expand on that? Is that something you're going to own the IP through or what's the vehicle there?

Eric DeMarco -- President and Chief Executive Officer

The primary IP related to that program the company had already developed and they own. The company has several hundred patents or patents pending that -- these are next-generation engine programs with specific platforms in mind. So that is -- you found one. That is one of many that they have received in the past couple of years, which are pointing, Josh, to those 12 opportunities, which are sitting right here in front of me as I'm talking to you, which we're getting designed into and which we expect to be the engine for, going forward, once they get into production.

Josh Sullivan -- Seaport Global -- Analyst

Got it. And then just on the current drones, you're using third-party jet engines for propulsion. Is there going to be an opportunity to use FTT engines at some point in the target drone business at some point?

Eric DeMarco -- President and Chief Executive Officer

Probably, pn the existing target drones, probably not because once they're designed in, they're qualified and they're approved by the customer, you don't want to change it out in the middle of a production run, a multiyear production run. However, on our tactical drones, going forward, virtually all of them. And on new target drones, the answer is, yes. KTT/FTT, who will be the vertically integrated engine.

That's the objective.

Josh Sullivan -- Seaport Global -- Analyst

And then is there any way to update the anticipated size of the orders that we should be looking for following the -- a successful VALKYRIE test?

Eric DeMarco -- President and Chief Executive Officer

I am not -- as I said on my prepared remarks, Josh, we -- in the past month, we've recently met with a number of customers, including at the Pentagon. And which is why I said this is going to happen. This is happening. It's no longer a question of if, it's when, and the when is coming in.

So I don't want to get ahead of the customer and -- I'm not going to do that. So not yet, not yet. Josh, importantly, on the question I think that Ken asked, the fact that Boeing is making the investment that they're making and them coming after this, that validates this market that we've been going after and we've got the lead in. That's how we see it.

That's probably the best validation external data point there is.

Josh Sullivan -- Seaport Global -- Analyst

Got it. And then just one last one. On the new Oklahoma facility, I think you made some comments there, but can you just provide any color how that's coming along? Any progress there?

Eric DeMarco -- President and Chief Executive Officer

Yes, on track. The first drone came off the line last month. We're going to have a significant function there with Senator Inhofe and his staff. And I think Senator Lankford is going to be there also.

This is a big deal. These are -- we understand this facility. We are going to be the only provider of a entire aircraft, ready to fly in Oklahoma. So they are big supporters of ours.

We're going to ramp up throughout the year, and then next year's quantities are very, very significant once we're 100% set up there.

Josh Sullivan -- Seaport Global -- Analyst

OK. Thank you.

Eric DeMarco -- President and Chief Executive Officer

Sure.

And our next question comes from the line of Michael Ciarmoli of SunTrust. Your line is now open.

Unidentified speaker

Good afternoon. This is George Sica on the line for Mike. First, congratulations on the margin performance. Multiyear high.

That's awesome.

Eric DeMarco -- President and Chief Executive Officer

Yes. Thank you. As we've been talking, we've been receiving inbounds on that. Thank you.

And we're looking forward to continuing to ramp going forward.

Unidentified speaker

Yes, I come from industry. I know how hard it is to get it up. So great job.

Eric DeMarco -- President and Chief Executive Officer

Thank you very much.

Unidentified speaker

What changed that made you pull the trigger on the acquisition now? What was different now versus previous times?

Eric DeMarco -- President and Chief Executive Officer

So if you could see me, I'm smiling. And the reason I'm smiling is we have been working with the owners, the founders, Shirley and Joe, for 1.5 years. So we have been tracking this. We have been working with them, understanding the technology, understanding what they want to do and their ambitions which are very big, very large, understanding the programs they were going after.

And additionally, over the past 1.5 years and, most recently, the past three and six months, we know this next generation of drones is about to happen. We know these next generation of extended-range weapon systems is happening. You can see that out there. Just take a look at JASSM-ER, Harpoon-ER.

You can see the extended-range weapons that are coming. And this market, these small engines, this technology is not current, and this company is disruptive. They are favored by the government customer, favored by them. And we've been working with the customer, we've been working with this company and this has all come together, and so that's the picture of why we did it now.

Unidentified speaker

You mentioned something very interesting in your comment about 2019 about the drone mix. You mentioned that for 2019 most of it's going to be driven by target drones. When does the mix shift and become more equal, where tactical is an equivalent portion of the revenue mix versus target? Is that something that you can expect in 2021?

Eric DeMarco -- President and Chief Executive Officer

That's a very fair question. So, the mix in 2019 does not include any, what I'll call, production units for tactical drones. OK? The VALKYRIE is going to fly very soon as the Air Force announced in December. We could get -- if we were to receive an order for 25 or 30 VALKYRIEs before the end of the year at $3 million each, 15-month -- 15-, 18-month production period, that mix could substantially change in 2020.

Unidentified speaker

Yes. go ahead. I'm sorry.

Eric DeMarco -- President and Chief Executive Officer

No, another one I want to mention is Program F. That system is flying today and it's being pulled to the left. And we're going to be doing a number of demonstrations, including some expected very interesting demonstrations in the middle of the year. If those are successful and that program goes, end of this year and next year we could get an order for a couple hundred of those at $300,000, $400,000 each.

Unidentified speaker

OK. And that seems like those are your two top opportunities in the near term, VALKYRIE and Program F.

Eric DeMarco -- President and Chief Executive Officer

Gremlins, with our partner Dynetics. The Gremlins are going to -- the demonstration is scheduled in the second quarter. I am not going to get ahead of our partner Dynetics, but there is significant customer interest in this system. So we've got -- Thanatos is going to be significant next year.

Unidentified speaker

And I just -- my last question, could you just familiarize us all again just once more on how many programs do you have in your -- in the hypersonic domain? And does FTT have any ongoing work in that domain? And that's my last question. Thank you.

Eric DeMarco -- President and Chief Executive Officer

Yes. So, So FTT, I'm going to go in reverse order, FTT absolutely has work in the hypersonic domain. All right? There are two programs that I can tell you about that we have been or are involved in on the hypersonic side: High Fire and High Cause. I cannot talk to you about any of the other ones.

I'm just not going to do that.

Unidentified speaker

Thank you very much.

Eric DeMarco -- President and Chief Executive Officer

Sure.

Operator

And our next question comes from the line of Mike Crawford of B. Riley FBR. Your line is now open.

Mike Crawford -- B. Riley FBR -- Analyst

Thanks. Can you remind us the margin you're getting now on full-rate asset production and the steps it might take to increase margin on targets like asset toward those levels as you get more experienced in producing those drones?

Eric DeMarco -- President and Chief Executive Officer

Including the drone, ancillaries, payloads, etc. etc., it's mid-teens.

Mike Crawford -- B. Riley FBR -- Analyst

On the asset now, but the -- you say assets I would imagine would be mid-single digits at best this year?

Eric DeMarco -- President and Chief Executive Officer

Yes, yes. And we're looking for that when we -- as we get the full-rate production. Again, assuming the aircraft, payloads, spares, ancillaries, similar margin profile.

Mike Crawford -- B. Riley FBR -- Analyst

And what about for tactical drones?

Eric DeMarco -- President and Chief Executive Officer

Similar margin profile.

Mike Crawford -- B. Riley FBR -- Analyst

OK. And then your RSS business has been using these Terrier, Malamute, Oriole sounding rockets. What is the status of your, I guess, ability or exclusive -- exclusivity -- exclusive ability to use these rockets for ballistic missile purposes?

Eric DeMarco -- President and Chief Executive Officer

The primary ballistic missile target system includes a rocket called the Oriole. We have exclusive perpetual rights, including a capped pricing grid, for these for three purposes: ballistic missile targets, sounding rockets, and suborbital systems. And if you look up suborbital systems, that's a hypersonic system. So we have a very important and valuable asset here,which is we believe one of the reasons why there are 3 large opportunities that are expected to be awarded this year, one of them imminently.

None of which we've included in our forecast. And that IP and that system we think is a big differentiator for us.

Mike Crawford -- B. Riley FBR -- Analyst

OK. All right. Thank you.

Eric DeMarco -- President and Chief Executive Officer

Thank you.

And our next question comes from the line of Joe Gomes of Nobel Capital. Your line is now open.

Joe Gomes -- Nobel Capital -- Analyst

Good afternoon.

Eric DeMarco -- President and Chief Executive Officer

Good afternoon.

Joe Gomes -- Nobel Capital -- Analyst

Just wanted to go back to FTT for a second here. You said you've been working with them for, like, 18 months. Were you the only bidder here? Why did the owners decide to sell? I mean, it's great that they're staying but just trying to understand why -- what their thought process was as to why they decided to sell to you guys. First part of it --

Eric DeMarco -- President and Chief Executive Officer

They see a very -- that one is easy. They see a very large production ramp coming, and they felt more comfortable doing it with a similar partner that focuses on affordability, that is highly technical. We are a highly technical company, as you know. They are very good at rapidly developing, demonstrating, and fielding something; so are we.

OK. Obviously, they see our drones. They know where our drones are going to be over the next several years. They can integrate their engines into our drones.

This is why they agreed to structure it this way, with selling 80.1% and keeping 19.9%, because they -- where they can put that 19.9% to us or we can call it in the future because their business plan in phenomenal and they believe that they are going to hit a grand slam and they are going to participate in that grand slam with us with that 19.9%.

Joe Gomes -- Nobel Capital -- Analyst

OK. And you said, I think, they're working on or bidding on 12 different type programs. Is there any potential for conflicts of interest, so to speak, once you start putting these engines in your drones or some of these programs that they're working on where some other outside customers would feel uncomfortable using their engines?

Eric DeMarco -- President and Chief Executive Officer

We see no risk of that at all. None.

Joe Gomes -- Nobel Capital -- Analyst

OK. And then one last one, I think you mentioned that the VALKYRIE is expected to fly soon. And I happened to see an article today that said it's to take flight next week. Is that accurate?

Eric DeMarco -- President and Chief Executive Officer

We are coordinating closely with the United States Air Force on any official information related to this, and that's all I'm going to say.

Joe Gomes -- Nobel Capital -- Analyst

OK. Thank you very much.

Eric DeMarco -- President and Chief Executive Officer

And our next question comes from the line of Sheila Kahyaoglu of Jefferies. Your line is now open.

Sheila Kahyaoglu -- Jefferies -- Analyst

Good evening, Eric. And thank you for the time. Can we talk about your $6.8 billion bid pipeline? Kind of maybe can you talk about what's in there or how it's changed, and how much of it is Unmanned?

Deanna Lund -- Executive Vice President and Chief Financial Officer

Sure, Sheila. This is Deanna. So in total we've got about $1.8 billion that's been submitted already of that $6.8 billion, and the Unmanned piece is roughly $1.6 billion. So there are number of opportunities that actually could be entered at a weighted value of much less than what is expected.

So for instance, there are some large opportunities that for purposes of tracking our guys only put in as dollar of value. So it actually is higher than the number that we actually report. But it is, as I said, about $1.6 billion of Unmanned, and $1.8 billion of the total has been submitted already.

Sheila Kahyaoglu -- Jefferies -- Analyst

OK. Understood. And then in terms of the Unmanned revenue profile of $250 million potentially, how could we think about the contributors of that? I'm guessing AFSAT, obviously, is a good base. And how do we think about the timeline of when contracts come in? Eric, you went through that on the call.

It seems like MAKO is in Q2 now. You'll have Gremlin coming in. You mentioned APOLLO is the new one. I was wondering if you could elaborate on that a bit.

Eric DeMarco -- President and Chief Executive Officer

Yes. So the $250 million number you mentioned, that is substantially all target drone related. OK? Substantially all of that, we have the programs. They're ramping.

So we have the Air Force program, which was our 167 target drone. That is its full-rate production, but quantities increasing as off-tempos increase for a peer/near peer threat fight. The SSAT program I mentioned today with the U.S. Navy.

We are in LRIP 2. LRIP 3 is coming. Full-rate production is going to be next year. We're going to get that award.

That's why initial operating capability today was important. So that U.S. Navy contract, SSAT, that is going to be one of the big drivers of getting to the $250 million as that goes from LRIP 2 this year, LRIP 3 next year, to full-rate production. We have two programs with the U.S.

Army. They're both new. 2 different drones. They are both ramping.

We have a program with a customer. It is ramping to full-rate production in two years from now. The international program we announced with Sweden where they are doing target drone threat representations for other militaries. That is going to begin in the middle of this year, and that one is going to ramp.

That's a $100 million base. We have a program with Kinetic. They're our teammate. They run the weapons ranges for the U.K.

It's called the CAPS program. They have a 20-year contract. They're 10 years into it. They signed a 10-year contract with us.

We're going to -- we're providing them target drones. That is ramping. So those are all the target drone programs we have under contract, sole- source, that are going to drive us toward that $250 million. And then in addition to that we provide drones to multiple international customers.

International customers that buy U.S. weapon system, they want to exercise them against best and state-of-the-art drones in the world. Those are ours. So, we have programs with Taiwan -- I can only mention some of these, South Korea, France.

I'm not going to mention the other ones because I'm not sure I can.

Sheila Kahyaoglu -- Jefferies -- Analyst

OK. OK. Appreciate the color. Thank you.

Eric DeMarco -- President and Chief Executive Officer

Yes.

Operator

Our next question comes the line of Seth Seifman of JP Morgan. Your line is now open.

Seth Seifman -- J.P. Morgan -- Analyst

Thanks very much, and good afternoon. To start off, a quick question about the acquisition. What made you decide to structure it the way that you did in terms of the mix of cash and equity?

Eric DeMarco -- President and Chief Executive Officer

It was a sit-down with the owners. And as I think -- as I mentioned a minute ago, they are -- they believe that they are going to hit a grand slam home run. They believe with us they're going to hit a double grand slam home run and they wanted equity. As part of this work, since they took stock, they did due diligence.

They understand all of our drone programs. They want to get their engines in those drone programs. They see what that's going to do for the performance of the drones and the affordability. So they see a very significant upside in Kratos stock.

So they took some cash now and they got big uppers with Kratos stock and with the 19.9%.

Seth Seifman -- J.P. Morgan -- Analyst

Right. OK. And then I apologize if you mentioned this earlier, but in terms of the guidance for '19 can you break that down between the two segments on the sales and the adjusted EBITDA?

Deanna Lund -- Executive Vice President and Chief Financial Officer

Seth, are you talking about between KGS and Unmanned?

Seth Seifman -- J.P. Morgan -- Analyst

Exactly.

Deanna Lund -- Executive Vice President and Chief Financial Officer

OK. We actually don't provide that guidance. We only provide it on a consolidated basis.

Seth Seifman -- J.P. Morgan -- Analyst

OK. Any qualitative color maybe?

Eric DeMarco -- President and Chief Executive Officer

Qualitative color. OK. As I mentioned, on the drone side LRIP 2 is coming in a little -- LRIP 3 looks like it's going to come in a little lower than we initially -- than the Navy initially announced for SSAP. And the issue with the government shutdown, and we have a number of international drone customers that we've pushed out as the backlog on the export licenses gets cleaned up.

So our Unmanned business, the trajectory, it's significant, but I don't want to get into the details here, because I've got -- I don't want to get into the details.

Seth Seifman -- J.P. Morgan -- Analyst

Got it. OK. And then maybe just as the last one, you talk about the opportunity on the tactical side being greater than on the target side, which I think makes sense. And you've kind of talked about a time frame when you ramp up to that $250 million on the target side being kind of over the next three to four years.

To see your ramp pass that level on the tactical side is something that would be -- the time frame on that, is that a few years beyond when you'd reach that point on the target side?

Eric DeMarco -- President and Chief Executive Officer

Well it -- obviously, it depends. I gave an example few minutes ago. I'll give a separate example. Gremlins, with our partner Dynetics, if successfully demonstrates in Q2 of this year.

If by the end of this year or early next year an order was to come in for 200 Gremlins, at $700,000 each, that would significantly change the mix, as I mentioned before. And if we got some VALKYRIEs on top of that, at $2 million or $3 million each, a couple of three years out it could flip entirely where the tactical business revenue and profit is passing the target business, which is what we see. As I mentioned, we've got six customer-funded programs right now: VALKYRIE, MAKO, Program F, Thanatos, AETHON and Gremlins. We have three more that I think are going to be funded before this year is out: Spartan is going to be funded, APOLLO is going to funded and ATHENA.

They're all going to be funded. So this is happening and, as I said before, this is not if anymore. This is when, and the when is coming.

Seth Seifman -- J.P. Morgan -- Analyst

Great. OK. Excellent. Thanks very much.

Operator

And next we have a follow-up question from Noah Poponak of Goldman Sachs. Your line is now open.

Noah Poponak -- Goldman Sachs -- Analyst

Eric, given that you had the revenue slippage out of the fourth quarter, out of the end of 2018, certainly there are multiple large growth opportunities in the business but I think in the industry in general, not just specific to you. And when someone is growing quickly or ramping, it's easy to have things slide to the right or easy to have slippage. And you've got a little bit of a back end-loaded year. So question is, what are the two or three pieces of your 2019 revenue guidance or specific programs, where there's most concern or the most risk of slippage from '19 into '20?

Eric DeMarco -- President and Chief Executive Officer

OK. Our Unmanned Systems business is pretty substantially bolted in with the Navy, the Air Force and the Army programs. So Unmanned Systems is, I'm going through this in my head, pretty substantially bolted in. The one in the Unmanned area that moved on us, the DIU program.

As you know, Raj Shah, who we knew very well, he left. Michael Brown took over. I know him. I've met with him.

We're tracking for a Q2 award there. We're tracking. I think we're going to get it. That's the one maybe, but I'm highly confident we're going to get it based on recent discussion.

Our Modular System, our C5ISR business, is pretty bolted in on with primes on weapon systems like the ones I went through. You know what, the one I see, potentially, those two services contracts we won. We won the radar contract and we won the high-powered laser contract, and we've won them. They're each multiyears, but they're ramping slower that the customer's bid plan.

And so those two, which are lower margin, so I think we're going to be fine on margin, those are the two that if they don't ramp, if we're not ramped headcount where we think we should be by the middle of the year, that could be a flashing yellow light.

Noah Poponak -- Goldman Sachs -- Analyst

OK.

Eric DeMarco -- President and Chief Executive Officer

Unidentified speaker

Just one quick question. It seems -- going back to again what you had previously mentioned, the larger players are really qualifying this opportunity. It's real. It's coming.

You've got other multi-billion-dollar competitors entering the market, and you've kind of shown a little bit of your strategy. You're picking very critical technologies, bringing them in-house, giving yourself a long-term discriminator in terms of the product offering. It seems like this OKC facility, is this going to be some type of center of excellence for all of the target drones? And will it serve a dual-use manufacturing capacity, target, and tactical? And that's my question. Thank you.

Eric DeMarco -- President and Chief Executive Officer

It will ultimately be the tactical drone center of excellence.

Thank you very much.

Eric DeMarco -- President and Chief Executive Officer

Yes. You got it. OK. There are no further questions? We look forward to speaking to you when we report Q1 in a couple of months.
