Grumman F2F
The Grumman F2F was a single-engine, biplane fighter aircraft with retractable undercarriage, serving as the standard fighter for the United States Navy between 1936 and 1940. It was designed for both carrier- and land-based operations. ==Design and development== Grumman's success with the two-seat FF-1, which was significantly faster than even the single-seat fighters of its time, resulted in a contract for the single-seat XF2F-1.〔Jordan, Corey C. ("Grumman's Ascendency: Chapter Two." ) ''Planes and Pilots Of World War Two,'' 2000. Retrieved: 22 July 2011.〕 Armed with two .30 caliber (7.62 mm) machine guns above the cowl, the new design also incorporated watertight compartments to reduce weight and improve survivability in the event of a water landing.〔 The prototype first flew on 18 October 1933, equipped with the experimental XR-1534-44 Twin Wasp Junior radial engine, and reached a top speed of at - faster than the FF-1 at the same altitude.〔 Maneuverability also proved superior to the earlier two-seat aircraft.〔
