The Grumman FF-1 was an American naval fighter, which was in service with the US Navy in the 1930s. Its prototype, the XFF-1, took to the air for the first time on December 29, 1931. After satisfactory completion of several tests in Anacostia, deliveries of the first 27 production aircraft began in April 1933. They were assigned to the USS Lexington's VF-5B Squadron of the US Navy. They would be withdrawn from front line service in 1936, to be replaced by the F3F-1.
