Mitsubishi Ki-51 (Sonia)
Technical Information

Background
Single engine ground attack aircraft with a crew of two that carried a mere 441 lbs of bombs and was armed with only three 7.7 machine guns (two in wings, one flexible gun for rear gunner). Despite its apparent obsolescence it was never replaced. Pilots and ground crews liked the plane because it was easy to fly, maintain, and operate from small airfields at the front lines.

Reconnaissance Version (Guntei)
Army recon version

Assault Version
The assault version had armor plating protecting the pilot and oil tanks, and bomb racks.

Production
A total of 2,388 were built.
