Comparing: T110E5 vs. FV215b

Developed from 1952 as a heavy tank with more powerful armament, compared to the T-43 (M103). Restrictions were placed on the vehicle sizing as the tank was supposed to pass through the narrow tunnels of the Bernese Alps. Several designs were considered, but the project was canceled. No vehicles were ever manufactured.

Proposed plan for a heavy tank on the basis of the Conqueror Mk. II. Unlike the production model, this modification featured rear placement of the fighting compartment. No prototypes were manufactured.
