Kit #AA2022. 1/72 scale. Highly-detailed resin kit with decals. In 1964, the U.S. Army launched the AAFSS specification, calling for an helicopter with a high cruising speed and long-time hovering capability. Sikorsky submitted the S-66 pusher tail rotor project that competed with Lockheed AH-56 Cheyenne. The AH-56 won the contest but failed to meet the expectations. Intending to replace the AH-56, Sikorsky developed a simplified AAFSS design that used a number of existing components to complete the S-67 Blackhawk. It was not only designed as a attack helicopter, but also served for other missions as troop transport, armed rescue and anti-submarine warfare. Sikorsky proposed the S-67 to U.S. Army as the AH-3 and later for the new AAH competition but it was never chosen for the fly-off. Flight tests were started by Sikorsky test pilots in 1970,and it established helicopter world speed record of 220.89 mph in the same year. In 1971, the U.S. Army joined the evaluation program but it was judged unsatisfactory to meet the new competition. The S-67 was finally destroyed in crash at 1974 Farnborough air show.
