The Sikorsky S-62 was a single turbine engine, single rotor amphibious helicopter originally developed as a commercial venture by the Sikorsky Aircraft Corporation of Stratford, Connecticut. It was used by the United States Coast Guard as the HH-52A Seaguard primarily for search and rescue, and now has been replaced by non-amphibious types such as the HH-65 Dolphin which rely on using a winch to retrieve passengers from a hover.

[edit] Design and development
A number of S-62s were bought by the US Navy Bureau of Aeronautics for the US Coast Guard for use as a search and rescue helicopter. Intitially designated HU2S-1G Seaguard, it was re-designated as 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.
The turbine powered S-62 could carry more weight and fly faster than the H-19 (S-55). The aircraft was first conceived and designed to be amphibious so that flotation gear would not be required for over water flights, and rescues could be made by landing on the water. The fuselage is watertight for landings on water or snow. Two outrigger floats resist pitching and rolling on the water. Although the HH-52A looks very different from the Sikorsky H-19, it used many of the same components.
