J2F-2 Duck

The Grumman J2F‑2 Duck was a versatile amphibious biplane built for the United States Navy during the early 1940s. Developed from the earlier J2F‑1 prototype, the Duck first flew in 1940 and entered service in 1942, where it performed utility, rescue, and transport missions throughout World War II. Its standout feature was the innovative retractable landing gear that folded into the fuselage, allowing smooth transitions between water and land operations without compromising the hull’s watertight integrity. Powered by a 1,200‑horsepower Pratt & Whitney R‑1830 Twin Wasp radial engine, the aircraft could carry up to 1,500 pounds of cargo, two crew members, and up to five passengers, while maintaining a range of roughly 1,300 miles and a top speed of 210 mph. The high‑wing, equal‑span biplane configuration provided excellent lift at low speeds, facilitating short takeoffs from rough seas. Over 1,000 Ducks were produced, serving not only the Navy but also the Coast Guard and Marine Corps. Their reliability and ability to operate in remote Pacific islands made the J2F‑2 a critical asset in rescue missions, logistical support, and aerial observation, cementing its place as a notable example of amphibious aircraft engineering in aviation history.
