Sikorsky H-34 Choctaw

The Sikorsky H-34 (company designation S-58) is a piston-engined military helicopter originally designed by American aircraft manufacturer Sikorsky as an anti-submarine warfare (ASW) aircraft for the United States Navy. It has seen extended use when adapted to turbine power by the British licensee as the Westland Wessex and Sikorsky as the later S-58T.

H-34s served, mostly as medium transports, on every continent with the armed forces of twenty-five countries. It saw combat in Algeria, the Dominican Republic, Nicaragua, and throughout Southeast Asia; other uses included saving flood victims, recovering astronauts, fighting fires, and carrying presidents. It was the last piston-engined helicopter to be operated by the United States Marine Corps, having been replaced by turbine-powered types such as the UH-1 Huey and CH-46 Sea Knight. A total of 2,108 H-34s were manufactured between 1953 and 1970.


Roles included utility transport, anti-submarine warfare, search and rescue, and VIP transport. In its standard configuration, transport versions could carry 12 to 16 troops, or eight stretcher cases if utilized in the MedEvac role, while VIP transports carried significantly fewer people in much greater comfort. A small fleet of H-34 helicopters served US Presidents Dwight D. Eisenhower and John F. Kennedy from 1958 to 1961 using the call sign Army One.
