Lockheed Martin has unveiled a small UAV that was used by the Skunk Works to investigate the stability and control of a stealthy, arrow-shaped design. The X-44A first flew in 2001 and was followed by two larger UAV developments, one of which was revealed 12 years ago, and another which remains classified. The company is preparing to reveal details of its entry for the U.S. Navy’s MQ-25 unmanned carrier-borne aircraft, which have been closely held until now.
