Lockheed Martin X-44A

The X-44A was a low-cost technology demonstrator that led to more sophisticated stealthy unmanned aircraft.  

Built by the famed Skunk Works, the X-44A successfully tested multiple technologies.  Its composite structure airframe was quickly built using advanced manufacturing techniques.  The X-44A design refined tailless aircraft aerodynamics and flight controls.  The test program also improved Lockheed Martin’s unmanned command and control system.

The X-44A first flew in 2001, before other contemporary stealthy, flying wing unmanned aircraft.  It also supported other test programs, including a deck-handling demonstration for US Navy carriers.  The X-44A was not publicly revealed, however, until 2018. 

The X-44A came to the Museum and was put on display in October of 2020.
