Military Aircraft H-34A CHOCTAW Photo By S. H. A. A. |
| The S-58 was one of the first true helicopter work-horses, and first flew in March 1954 as the XHSS-1 prototype in response to a naval requirement for a ship borne anti-submarine helicopter. The type featured a modern looking fuselage with tail wheel landing gear, and an innovatory feature was the location of the engine low in the nose with a long shaft running obliquely through the forward fuselage. The type was built up to 1970, production amounting to 2,261 for civil, military, and naval use. The Choctaw interred service in September 1955 as a utility type generally used for the carriage of troops, and played an important part in France's North African war of the early 1960s Some S-58s have been revitalized by the retrofit of a Pratt & Whitney Canada PT6A-3/6 coupled turbo shaft. |
