The Nakajima A1N, or Navy Type 3 Carrier Fighter, was a Japanese carrier-based fighter of the late-1920s and early-1930s. It was a licensed copy of the British Gloster Gambet fighter, built by the Nakajima Aircraft Company for the Imperial Japanese Navy. Approximately 150 were built in two versions, the A1N1 and A1N2. This machine served on aircraft carrier Akagi in 1927.
