The Sikorsky S-61A, a versatile twin-engine turbine helicopter, revolutionized both military anti-submarine warfare and commercial offshore operations. First flown in 1959 as the XHSS-2 Sea King prototype, it was a large amphibious helicopter powered by two General Electric turboshaft engines and capable of carrying up to 28 passengers or substantial cargo loads. With a main rotor diameter of 62 feet and maximum takeoff weight of 19,000 pounds, the S-61A became one of the most widely used helicopters of its era. The aircraft was manufactured by Sikorsky Aircraft Corporation from 1961 through 1980.
