The 22nd Crash Rescue Boat Squadron (22nd CRBS) was a U.S. Air Force combat search and rescue unit formed during the Korean War. While its original task was ocean rescue of downed pilots, its speedy and well-armed boats soon became prime vehicles for inserting spies, espionage agents, and sabotage parties into enemy territory for the 6004th Air Intelligence Service Squadron. Despite the hazards of both their overt and covert missions, the airmen of the 22nd CRBS never lost a boat during their clandestine operations in the war.
