The Sikorsky H-34 "Choctaw" (company designation S-58) is an American piston-engined military helicopter originally designed by 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. Mission Systems SH-34G (HSS-1) Seabat The Navy SH-34J had dipping Doppler navigator, an AN/AQS-4/-5 dipping SONAR, and Automatic Stabilization Equipment (ASE), a helicopter autopilot system, which allowed the helicopter to achieve a hover and maintain position over the SONAR transducer without pilot assistance.

Model C/N Operators Sikorsky began work on the S-58 in 1951 as a general purpose utility machine and as a more capable anti-submarine platform for the US Navy, to follow the S-55. The Sikorsky S58 was one of the most successful piston powered mid size helicopters built. Sikorsky developed the S58 in response to a US Navy requirement for an anti submarine warfare helicopter. The Sikorsky S-58 was an all-purpose transport flown by the U.S. Navy, Marines, Army, and Coast Guard as well as foreign and domestic commercial operators.

The Sikorsky S-58, also known as the H-34 Choctaw in the United States, is a historic helicopter that has left an indelible mark on the aviation industry. Developed by Sikorsky Aircraft in the late 1950s, the S-58 quickly became a workhorse for various military and civilian applications. Its versatility, reliability, and robust design made it a. Sikorsky Aircraft which stopped the production in series of the S-58 in 1969 (the last one left the assembly line in January that year), launched a series of test and studies that showed that the idea was both economically and operationally interesting. 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. The Sikorsky S-58 was first flown on March 8th 1954 and entered service as the HSS-1 for the U.S. Navy and Marines and as the H-34 for the U.S. Army and Air Force.. The poor engine performance shown by the Sikorsky S-55 prompted the IAF to look for a replacement and an Israeli delegation journeyed to France to study helicoter use by the French.

1958 Sikorsky S-58 N887. The piston-powered S-58 was the civilian version of the H-34 military helicopter, and was one of the first such machines widely used by industry, serving in roles as diverse as airline transport, early offshore support and as a 'flying crane', able to lift external loads up to 4,000 pounds.

The Sikorsky S-58 was a US-American piston-engine submarine hunting and transport helicopter. In the United States Air Force, the S-58 was uniformly designated H-34 from 1962 onwards. With a crew of two men, the transport version could carry up to 16 passengers or 1350 kg of cargo or, in ambulance service, eight wounded persons on stretchers.. Another winner for Sikorsky in the fifties was the Model S-58.The prototype was developed to meet a US Navy specification for a more advanced antisubmarine helicopter than the S-55.Designated XHSS-1, it first flew on 8 March 1954 and the first production aircraft, nicknamed "Seabat", was ready by September.The Marine Corps adopted it in 1957 as "Seahorse" and the Army in 1955 as "Choctaw".
