J2F-5 Duck

The Grumman J2F‑5 Duck was a versatile amphibious biplane developed in the late 1930s for the United States Navy. Evolving from the earlier J2F‑1 and J2F‑2 models, the Duck incorporated a more powerful Wright R‑1820‑94 radial engine, enlarged fuel capacity, and refined hull shaping that improved seaworthy handling and payload capability. First delivered in 1939, the aircraft served as a utility transport, reconnaissance scout, and rescue platform throughout World II, operating from aircraft carriers, naval bases, and remote forward areas where conventional runways were unavailable. Its distinctive “boat‑like” fuselage allowed water take‑offs and landings, while the robust fixed‑gear undercarriage enabled conventional runway operations, giving commanders flexible deployment options. The J2F‑5 could carry up to 2,500 lb of cargo or 12 passengers, and its internal bomb bay accommodated a modest anti‑submarine loadout when required. Though production ended in 1945, the Duck’s combination of amphibious capability, reliability, and multi‑role adaptability influenced later designs such as the Grumman G‑21 Goose and contributed to the development of modern seaplane and tilt‑rotor concepts. Its legacy endures in museums and in the continued appreciation of amphibious aircraft in naval aviation history.
