The Sikorsky S-62 is a single turbine engine, single rotor amphibious helicopter originally developed as a commercial venture by the Sikorsky Aircraft Corporation of Stratford, Connecticut.


A number of aircraft were bought by the US Navy Bureau of Aeronautics for the US Coast Guard for use as a search and rescue helicopter and designated the HU2S-1G Seaguard. The HU2S-1G was re-designated the HH-52A Seaguard in 1962.

The HH-52A used a boat hulled shaped fuselage, smaller but similar to the US Navy's SH-3 (Sikorsky S-61), and was employed aboard the larger Coast Guard cutters and icebreakers. The S-62 used a single 1250 hp General Electric T58-GE-8 turboshaft engine, the same powerplant used on the larger twin-engined SH-3.
