The General Atomics FQ-42 Vengeance is an unmanned fighter aircraft with loyal wingman capabilities, currently under development by General Atomics Aeronautical Systems. The aircraft is one of the winning designs for Increment I of the United States Air Force's Collaborative Combat Aircraft (CCA) program and is intended to augment crewed fighter aircraft such as the F-22 Raptor, F-35 Lightning, and the planned Boeing F-47 fighter for air-to-air missions through manned-unmanned teaming (MUM-T).
