JF-2 Duck

The Grumman JF‑2 Duck was an evolution of the earlier J2F series, a rugged amphibious biplane designed in the late 1930s for the United States Navy and Marine Corps. First flown in 1939, the JF‑2 incorporated a more powerful Wright R-1820‑60 Cyclone radial engine delivering 1,200 hp, a strengthened all‑metal hull, and an enlarged fuel capacity that extended its range to over 1,400 miles. Its distinctive “metal‑skin” hull and retractable landing gear allowed seamless operation from both water and conventional runways, a capability that proved valuable for ship‑based reconnaissance, rescue missions, and utility transport during World II. The aircraft could carry up to three passengers or a modest cargo load, and its open cockpit provided excellent visibility for observation duties. Production numbers remained low—only a few dozen JF‑2s were built—but the type exemplified Grumman’s innovative approach to multi‑role amphibians. After the war, surviving Ducks were transferred to civilian operators, where they served as bush planes in remote regions. The JF‑2 Duck’s blend of durability, versatility, and straightforward handling left a lasting imprint on the development of later amphibious aircraft and on the doctrine of naval air utility.
