The United States Air Force examines how it would rescue downed pilots and other troops during a future battle. The Air Force wants to reduce its planned acquisition of combat rescue helicopters by one-third. The House version of the National Defense Authorization Act would require the Air Force to submit a report detailing its vision for the future of CSAR. CSAR pilots were more successful in the past against an opponent without aircraft or robust surface-to-air defenses. Finding solutions will be difficult for several reasons, including that any opponent capable of shooting down an F-35 would be an even greater danger. Autonomous drones might be used to rescue or replenish personnel in peril. Under consideration is the Agility Prime electric vertical-takeoff-and-landing vehicle as an independent, pilotless alternative. This initiative would undoubtedly need a substantial investment in artificial intelligence.
