Yellow Biplane – Smithsonian National Air and Space Museum, Steven F. Udvar-Hazy Center, Chantilly, Virginia

In 1934 the Naval Aircraft Factory in Philadelphia was tasked to manufacture a new primary trainer for the U.S. Navy. Following successful tests, this little biplane trainer was built in both land and seaplane versions. The Navy initially ordered 179 N3N-1 models, and the factory began producing more than 800 N3N-3 models in 1938. U.S. Navy primary flight training schools used N3Ns extensively throughout World War II. A few of the seaplane version were retained for primary training at the U.S. Naval Academy. In 1961 they became the last biplanes retired from U.S. military service.
