The Sikorsky H-5 (R-5 until 1948) is a helicopter built by the Sikorsky Aircraft Corporation, formerly used by the United States Air Force, and its predecessor, the United States Army Air Forces, as well as the United States Navy and United States Coast Guard (with the designations HO2S and HO3S).
During its service life, the H-5 was used for rescue and mercy missions throughout the world. It gained its greatest fame, however, during the Korean War when it was called upon repeatedly to rescue United Nations' pilots shot down behind enemy lines and to evacuate wounded personnel from frontline areas.
