Dubbed the Polecat, the unmanned aerial vehicle (UAV) is essentially a 90-foot flying wing that is capable of high-altitude flight. Although the Polecat is not ready for prime time, it might prove a worthy successor to other "Skunk Works" alumni, such as the U-2 and SR-71 spy planes and the radar-invisible F-117 stealth fighter.
But what really separates the Polecat from those past projects, and makes it so interesting from an investor's perspective, is that the vehicle was manufactured from "printed" parts rather than traditional machine-tooled components.
The parts are created through a technique more commonly known as 3-D rapid prototyping. Designs for individual parts are fed into a computer-aided design (CAD) system, then sent to an oven-sized box that serves as the "printer." Inside, a laser fuses together polymers or metal powder layer by layer until the part takes shape.
Various industries have used such processes for years to make prototype parts. But Lockheed has successfully constructed almost an entire airframe using the same process. This cuts manufacturing costs by reducing the numbers of tools needed to make a part, while dramatically reducing fabrication and assembly time.
It's too soon to know whether the process can be applied to other military or commercial aircraft. Obviously, Lockheed will need to manufacture those products to a much higher standard in order to safeguard their pilots and passengers. (Remember, the Polecat is unmanned.) But the 3-D manufacturing processes will only continue to improve with time.
As it does, Lockheed will likely use the process to gain a leg up on competitors such as Boeing
