Comparing: Matilda Black Prince vs. M7

This vehicle features a 6-pounder gun fitted in the A27 turret. Only one prototype was produced, after which development was discontinued due to complications with the turret mounting. The vehicle never entered service.

Development started in 1941. Initially, the vehicle was developed as a light tank; however, as the model gradually received extra armor and armaments, it was reclassified as a medium tank. Production of the M7 started by the fall of 1942. However, since the M7 was inferior to the mass-produced M4 Sherman in all parameters except speed and dimensions, the production was stopped. A total of 7 vehicles were produced.
