Grumman F3F-2 USN 1942 (1:48)

By the mid 1930s the USN realized that the modern fighter would have to be a mono-wing but development hadn��_t even begun. As a stop-gap measure they ordered the Grumman F3F-2 that was a much improved version of the F2F and could be in production in a relatively short time. The new aircraft had a larger engine that increased speed by 33 mph and the rate of climb form 205 to 2750 ft/min. Along with a larger engine came a larger three-bladed constant-pitch propeller and a larger rudder to compensate the first two improvements. The improvements also meant the service ceiling was increased from 27,200 ft to 33,200 ft.

A long relationship between the USN and Grumman Aircraft began in 1931 with the production of the Grumman FF-1 and 1933 continued with the F3F. The USN received the first F3F-2 on December 1, 1937 and the last of the sixty-four F3F-2 aircraft on May 11, 1938. The last F3F flew in front-line service at the end of 1941 when it was replaced by the Brewster Buffalo and the F4F Hellcat. The USN took 117 F3F-2s and F3F-3s and sent them to various bases around the USA for training and transport duties. The last F3F-2 was retired from military service in November 1943.
