The Sikorsky R-5 was the second helicopter type to go into full production for the U.S. Air Force.\u00a0 The R-5 prototype first flew in August 1943.\u00a0 When the U.S. Air Force became an independent service in 1948, the designation letter for helicopters was changed from \u201cR\u201d to \u201cH\u201d and the Dragonflies were redesignated H-4.\u00a0 The Dragonfly was also adopted by the U.S Navy and the Coast Guard under the designation HO3S.\u00a0 In 1946, the Dragonfly became the second helicopter to enter Coast Guard service under the Navy designation HO3S-1G.\u00a0 They were used to develop techniques and equipment for using helicopters in Air-Sea rescue operations.\u00a0 The success of the Dragonfly led to the expansion of the use of helicopters by the Coast Guard that continues today.\u00a0 A total of 9 Dragonflies served the Coast Guard from 1946 to 1959.<\/p>\n<\/div>\n\n\n\n\n\n\n\n\n\n\n\n
