Sikorsky S-62

The Sikorska S‑62, developed by the Sikorsky Aircraft Corporation in the late 1950s, was a twin‑engine amphibious transport that bridged the gap between the earlier S‑55 helicopter and the more modern SH‑60 series. First flown on 27 May 1958, the S‑62 entered service with the United States Coast Guard as the HH‑52 Seaguard, where it quickly proved its value in search‑and‑rescue, maritime patrol and air‑lift missions. Its hull, derived from the successful S‑55, was reinforced for water operations, while a high‑mounted three‑blade main rotor provided ample lift and stability. Powered by two General Electric T58 turboshaft engines, the aircraft could cruise at 110 knots, reach a service ceiling of 16,000 feet and carry up to 12 passengers or 2,000 lb of cargo. The S‑62’s ability to land on both sea and land made it a versatile platform for civilian operators, including airline and oil‑rig transport services. Although production ended in 1970 after 250 units, the S‑62’s design influenced later amphibious helicopters and cemented Sikorsky’s reputation for innovative vertical‑flight solutions, particularly in maritime environments.
