Sikorsky HH-52 Sea Guard Helicopter
The Coast Guard acquired 99 of the Sikorsky HH-52A Sea Guard helicopters, beginning in July 1962, and retired the last one in service 12 September 1989, replaced by the HH-65A Dolphin. During its long service, the HH-52A Sea Guard was the Coast Guard’s primary short-range, search and rescue helicopter.
The HH-52A was the military version of the Sikorsky Model S-62, the first turbine-powered helicopter to be certified by the U.S. Federal Aviation Agency. The HH-52A had a watertight boat-hull fuselage making it capable of water landings and takeoffs, a key factor for the Coast Guard in selecting the aircraft.
