1952 the Navy ordered a new ASW helicopter from Sikorsky. It was given the designation S-58 by Sikorsky and HSS Seabat by the Navy. The Marines knew it as the HUS Seahorse and the Army call it the H-34 Choctaw. After all this confusion it was settled, the civilian version would be S-58 and military would be the H-34 and SH-34. There were over 2,250 produced in various models.

The Sikorsky S-58 was a very successful general-duty helicopter. The radial engine was fitted in the nose as in the H-19, but the fuselage was more streamlined: the box-and-boom design of the H-19 was replaced by a simply tapering structure, the aft end of which could be folded. The type was known as HSS or HUS in USN and USMC service, and was license-built by Westland as the Wessex (with a turbine engine). The S-58 also pioneered airline helicopter operations. Some are still flying, often converted with turbine engines. 2261 were built.
