Naval Aircraft Factory N3n

Single Piston

The Naval Aircraft Factory N3N is a biplane primary trainer that earned the affectionate nickname 'Yellow Peril' for its bright chrome-yellow paint scheme and its role introducing thousands of U.S. Navy and Marine Corps aviators to flight during the 1930s and 1940s. Built at the Philadelphia Naval Aircraft Factory between 1935 and 1941, the N3N became the last biplane trainer used by American military forces and the most-produced aircraft ever manufactured by a U.S. government facility, with approximately 997 examples completed. Its tandem open cockpits, rugged welded steel-tube fuselage, and fabric-covered wings made it forgiving for student pilots while remaining robust enough for carrier deck operations and seaplane training—the amphibious N3N-3 variant could operate on wheels or twin floats. Powered by a 235-horsepower Wright R-760 radial engine, the N3N offered docile handling characteristics with a stall speed around 42 knots and a never-exceed speed of 135 knots, making it ideal for teaching basic aerobatics, formation flying, and carrier approaches. Its wide-track landing gear and low wing loading provided excellent stability during takeoff and landing, critical qualities for novice naval aviators learning to operate from pitching carrier decks. The type remained in active Navy service until 1961, an extraordinary 26-year operational lifespan that speaks to its reliability and effectiveness as a training platform. Today the N3N is a prized warbird among collectors and vintage aircraft enthusiasts, valued for its historical significance and gentle flying qualities. Most surviving examples are privately owned and flown at airshows and fly-ins, where their distinctive yellow livery and radial engine rumble evoke the golden age of naval aviation training. SkyMeter has tracked 16 flights across 6 airframes and 6 operators, with CLEALL WAYNE J the largest observed operator.
