This kit is in 1/700 scale. It includes 12x Westland Sea King Mk.50 as used by the Royal Australian Navy. They can also be used to represent Sikorsky SH-3, Westland HAS.5 and so on. The aircraft are unarmed. They are connected as a single sprue by a wire under the main body of the aircraft. Once the wire is cut the aircraft do not require any finishing.
According to Wikipedia: "The Westland WS-61 Sea King is a British licence-built version of the American Sikorsky S-61 helicopter of the same name, built by Westland Helicopters. The aircraft differs considerably from the American version, with Rolls-Royce Gnome engines (derived from the US General Electric T58), British-made anti-submarine warfare systems and a fully computerised flight control system. The Sea King was primarily designed for performing anti-submarine warfare (ASW) missions. A Sea King variant was adapted by Westland as troop transport known as the Commando."
