Sikorsky HH-52 Seaguard – Walk Around

V Sikorsky HH-52 Seaguard (company designation S-62) was a single turbine engine, three-blade 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 primarily for air-sea rescue. The HH-52 has been replaced by non-amphibious types such as the HH-65 Dolphin, which rely solely on the use of a winch from a low hover to conduct rescue operations.
