Royal Thai Police The Fletcher FD-25 Defender was a light ground-attack aircraft developed in the United States in the early 1950s.

Designed by John Thorp, the Defender was a conventional low-wing cantilever monoplane with fixed tailwheel undercarriage.

Provision was made for two machine guns in the wings, plus disposable stores carried on underwing pylons.

In Japan, however, Toyo acquired the rights to the design, and built around a dozen aircraft, selling seven (five single-seater attack versions and two two-seat trainers) to Cambodia,[1] and four to Vietnam.

Two (a single-seater[3] and a two-seater[4]) are on museum display at the Tokyo Metropolitan College of Industrial Technology in Japan.
