The Grumman F3F is a biplane fighter aircraft manufactured by Grumman for the United States Navy in the mid-1930s.
It was designed as an enhancement of the F2F and commenced service in 1936, marking the last biplane to be supplied to any American military aviation unit.
The aircraft was withdrawn from active squadrons by the end of 1941, prior to its potential involvement in World War II, and was succeeded by the Brewster F2A Buffalo.
The F3F, which featured the retractable main landing gear configuration designed by Leroy Grumman and first implemented on the Grumman FF, served as the foundation for a biplane design that eventually evolved into the significantly more successful F4F Wildcat, which replaced the inadequate Buffalo.
