Sikorsky S-70B-2 Seahawk

The S-70B-2 Seahawk is a twin-engine anti-submarine helicopter designed for ship-borne operations. The Sikorsky Aircraft Division of United Technologies Corporation in Florida, USA, manufactured the first batch of eight aircraft. Aerospace Technologies Australia (ASTA) at Avalon in Victoria assembled a second batch of eight aircraft. The final aircraft was delivered to the RAN in 1992. In addition to its primary warfare role, the S-70B-2, with its built-in winch and cargo hook, is also used extensively at sea to transfer personnel and for the vertical replenishment of stores to ships while they remain under way. With minor modification, the aircraft is capable of being converted to a troop-carrying role, lifting up to 10 troops at a time.
