Sikorsky H-34

what is it?

The Sikorsky H-34 (company designation S-58) is an American piston-engined military utility helicopter originally designed by Sikorsky as an anti-submarine warfare (ASW) aircraft for the United States Navy. A development of the smaller Sikorsky H-19 Chickasaw (S-55), the H-34 was originally powered by a radial engine, but was later adapted to turbine power by the British licensee as the Westland Wessex and by Sikorsky as the S-58T. The H-34 was also produced under license in France by Sud Aviation. The H-34 was one of the first successful military utility helicopters, serving on every continent with the armed forces of 25 countries.
