The Grumman F3F was based on the Grumman FF and F2F and was the last fighter aircraft delivered to the United States Navy that was designed as a biplane . It was introduced to the US Navy and Marine Corps from 1936 .
history
The F3F was created through an invitation to tender from 1934, which resulted in the order for a prototype on October 15, 1934. The first prototype , the XF3F-1, flew on March 20, 1935 , but pilot Jimmy Colins was killed as early as March 22, 1935 while demonstrating the aircraft to the US military. Despite further difficulties in testing the newly built prototype, an order for 54 F3F-1 machines was placed on August 24, 1935, the first of which were delivered in January 1936. The improved version F3F-2 followed in 1937, and the F3F-3 version in 1938. Due to the shape of the hull, the F3F - and the similar F2F - were referred to as “Flying Barrels”.
The machines were used on the aircraft carriers USS Saratoga , USS Ranger , USS Yorktown , USS Enterprise and USS Wasp , among others .
The F3F were no longer used in the Pacific War, as the last fighter squadron (VF-5) was withdrawn from active service on June 20, 1941. They then served as training aircraft and were taken out of service in November 1943.
For the oil company Gulf Oil , several civilian variants (G-22, G-32 and G-32A) were built from 1938. The two G-32 aircraft were used as UC-103 by the USAAF from November 1942 .
