Comparing: Waffenträger auf E 100 vs. T110E4

A proposal to mount a large-caliber antiaircraft gun on the chassis of the E 100 tank. The vehicle was to feature either 128- or 150-mm guns with an automatic loading system. However, the design project was never developed.

In 1954, a conference on future heavy tanks was held in Detroit. Alongside other advanced projects, the Chrysler Corporation suggested a new tank on the basis of the TS-31 project. The main goal was to make the tank fit the Bern national tunnel. Several variants were considered, but the project was canceled.
