Sikorsky R-6A Hoverfly II (S-49)

The R-6 was developed off of the proven successful R-4 to improve on certain characteristics and performance. In order to enhance performance, a completely new streamlined fuselage was designed and the boom carrying the tail rotor was lengthened and straightened. The main rotor and transmission system of the R-4 were retained. Initial production was by Sikorsky, but most examples were built by Nash-Kelvinator. Some of the later aircraft were fitted with more powerful engines. The R-6's First Flight was on the 15th of October, 1943 and was introduced into the USAAF (United States Army Air Forces) in 1945. The Primary Users were the USN (United States Navy), and the RAF (Royal Air Force).
