1:72 Scale Diecast metal and plastic parts ? Sikorsky S-61A SH-3 SH-3D Sea King Anti-submarine Helicopter - Spanish Navy - Length: 9.5" (fuselage) Rotor span: 11? A display stand is included. The model is already assembled and painted, however, the blades, and rotors need to be assembled. No glue is needed. The assembly for the rotor and the blades are very fragile, so one needs to be very careful when attaching the blades since it is very easy to bend or break things out of shape. The landing gear is fixed in the extended position. These helicopter models are really not toys, they are not made to be played with. They will not last long if played with. Moreover, these models are made to look realistic and faithful to the real thing, so little parts like landing gears, skies, weapons, pods and antennas are made from small parts and are very fragile. The Sikorsky SH-3 Sea King (company designation S-61) is an American twin-engined anti-submarine warfare (ASW) helicopter designed and built by Sikorsky Aircraft. A landmark design, it was one of the first ASW rotorcraft to use turboshaft engines. The Sea King has its origins in efforts by the United States Navy to counter the growing threat of Soviet submarines during the 1950s. Accordingly, the helicopter was specifically developed to deliver a capable ASW platform; in particular, it combined the roles of hunter and killer, which had previously been carried out by two separate helicopters. The Sea King was initially designated HSS-2, which was intended to imply a level of commonality to the earlier HSS-1; it was subsequently redesignated as the SH-3A during the early 1960s.
