The Department of Defense announced 11 new defense contracts on Tuesday. That may not sound like much, but thanks to two multibillion-dollar contracts among them, the total value of contracts awarded on the day could surpass $14.18 billion.

The biggest winner of the day was the Bechtel Group. The privately held construction and engineering firm won a "modification" adding $7.1 billion to the value of its contract to perform naval nuclear propulsion work at the Bettis & Knolls Atomic Power Laboratories. Nine other companies were named winners of slots under the Air Force's $6.9 billion NETCENTS-2 IT equipment contract.

As for the other firms winning defense contracts, they include:

  • Raytheon (NYSE:RTN), which won a new sole-source, firm-fixed-price contract worth up to $42.8 million, to supply "various radio parts and equipment" to the U.S. Navy and to the government of Australia. This contract runs through March 2016.
  • URS Group (NYSE:URS), recipient of a $13 million firm-fixed-price, indefinite-delivery contract to perform architect-engineering services for the U.S. Army Corps of Engineers, Mobile District, supporting the "beddown" (establishing of infrastructure needed to support deployment) of U.S. Air Force KC-46C aerial refueling tankers.
  • Northrop Grumman (NYSE:NOC), which was awarded an $18.5 million option exercise to build, install, and test modifications to the Multi-Role Tactical Common Data Link Ku Line-of-Sight and Ka satellite communications systems, for incorporation into Navy E6-B airborne early warning aircraft. This contract will now continue through November 2015.
  • Boeing (NYSE:BA), which won a $13.7 million contract modification funding the procurement of aircraft armament equipment for F/A-18E/F fighter jets and EA-18G electronic warfare aircraft. Specifically, these funds will be used to acquire 270 station control units, 13 aerial refueling stores (ARS) air probes, 13 ARS fuel probes, 26 ARS suspension lugs, 168 chaff dispenser covers, 26 ALE-50 dispensers, 26 ALE-50 protectors, 26 ALE-50 chassis, 26 ALE-67 mounting bases, 26 mounting retainers, and 12 centerline feed-thru plates. Deliveries should be complete by August 2015.
  • And Lockheed Martin (NYSE:LMT). Actually, Lockheed won two contracts Tuesday: a $10.4 million delivery order to perform engineering work on MH-60R Sikorsky Seahawk VHF Omni-directional Range/Instrument Landing Systems and other equipment for the government of Australia, as well as an $8.3 million contract modification adding funds for the purchase, upgrade, and support of Trident II (D5) ballistic missiles for the U.S. Navy. The former contract is to be completed by February 2016; the latter, by December 2014.
