|Primary user||United States Coast Guard|
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.
