Operational Context

Sikorsky HH-3F Pelican — long-range search and rescue helicopter

The HH-3F entered service in 1969 with enhanced avionics and rescue equipment. A boat-shaped hull allowed amphibious capability. The helicopter was designed for extended offshore missions.

Two turboshaft engines producing approximately 1,500 shaft horsepower each powered the aircraft. Cruise speed approached 120 knots (222 km/h). Maximum takeoff weight exceeded 22,000 pounds (9,979 kg).

The Pelican conducted thousands of rescues during its service life. It was gradually replaced by newer helicopters in the 1990s. The aircraft remains an important chapter in Coast Guard aviation history.
