Westland WS-61 Sea King is a British medium-range military transport helicopter, developed in 1969 by the Westland Helicopters aircraft manufacturer.

The Westland WS-61 Sea King military transport multipurpose helicopter was developed by British aircraft manufacturers in the second half of the 60s of the last century. To minimize the costs and time for designing an aircraft, the British aircraft manufacturer Westland Helicopters decided to use the model of the American Sikorsky S-61 as a base, however, the design of the aircraft underwent several adaptations, and, having decreased in size, became more maneuverable and effective in terms of its operational capabilities, although at the same time the volume of transported cargo or transported people has decreased.

The Westland WS-61 Sea King made its first flight in May 1969, and since the tests passed were quite satisfactory, the project was sent to production, where it became very popular, as evidenced by the fact that the release of this model It was waged until 1995, while 344 helicopters left the Westland Helicopters assembly line.

The Westland WS-61 Sea King model aircraft allows you to carry up to 12 military personnel onboard, however, as a rule, the current aircraft was not used to carry out the transfer of the armed forces, but was used either to transport large cargoes or to participate in search and rescue operations or was used as an anti-submarine.
