Sikorsky HH-3A Sea King

The Sikorsky HH‑3A Sea King, developed by Sikorsky Aircraft Corporation in the early 1960s, served as the United States Air Force’s primary long‑range search‑and‑rescue helicopter. Based on the naval SH‑3 Sea King, the HH‑3A entered service in 1962 and quickly proved indispensable during the Vietnam conflict, where its ability to operate at night and in adverse weather saved countless downed airmen. The helicopter’s twin General Electric T58‑10 turboshaft engines deliver 1,350 shaft‑horsepower each, providing a maximum speed of 156 knots and a range exceeding 600 nautical miles. Its spacious fuselage accommodates up to 12 passengers or a full medical evacuation team, while built‑in D‑band radios, rescue hoist, and de‑icing equipment support all‑weather missions. The HH‑3A’s robust airframe, amphibious floats, and foldable rotors enable carrier‑deck compatibility and operations from remote bases. Beyond combat, the aircraft played a pivotal role in civilian SAR, disaster relief, and polar expeditions, cementing its reputation for reliability and versatility. The HH‑3A’s legacy paved the way for later Sikorsky models such as the HH‑60 Pave Hawk, marking a significant milestone in the evolution of modern rescue aviation.
