Boeing's Drone Fighter Jet Sidekick Just Took Its First Flight Test flight of the Boeing-built drone-jet hybrid prototype developed for the Royal Australian Air Force as part of its Loyal Wingman program. (Courtesy of Boeing) 2 Mar 2021 The Royal Australian Air Force's first Boeing-built, drone-jet hybrid prototype -- part of its "Loyal Wingman" program -- made its first test flight last week. The company said Monday that it had held a series of taxi, takeoff and flight tests for the drone, which could someday play sidekick to fourth- and fifth-generation fighter jets, according to a news release. "The Loyal Wingman's first flight is a major step in this long-term, significant project for the Air Force and Boeing Australia, and we're thrilled to be a part of the successful test," said Air Vice-Marshal Cath Roberts, head of Air Force capability for the RAAF.
