Comparing: AT 8 vs. Churchill Gun Carrier

The vehicle was conceived as a breakthrough tank. The design project evolved from the AT-7 project, and both projects were submitted at the same time. No prototypes were built because the A39 Tortoise was preferred.

The vehicle was developed on the basis of the Churchill tank. The cabin with the 3-inch gun was placed in the front. Initially, 100 vehicles were ordered. Later, the order was reduced to 24 vehicles. Eventually, a total of 50 vehicles were manufactured from 1941 through 1942. However, they never saw action.
