|Role||High-altitude endurance unmanned aerial vehicle (UAV) technology demonstrator|
The Lockheed Martin X-44A is an unmanned aerial vehicle (UAV) technology demonstrator built by the Lockheed Martin Skunk Works.
After the 1999 cancellation of the RQ-3 Darkstar, Lockheed Martin decided to build a technology demonstrator for a potential family of flying wing UAVs that could be used for combat and non-combat roles. The resulting X-44A (although apparently unrelated to the previously developed X-44 MANTA) was built in 1999 and first flew in 2001, representing an interim design between the Darkstar and P-175. However, Lockheed Martin kept the X-44A under wraps until February 2018.
The X-44A is reportedly made from nano-carbon fiber and is powered by a Williams F122 turbofan engine. The wingspan of the X-44A is 30 feet (9.1 m), half of that of the RQ-170 Sentinel.
The X-44A is currently on display at the National Museum of the US Air Force, near Dayton, Ohio, in the Research and Development gallery housed in Building 4.
