Vehicle description

Wargaming Tankopedia

A late 1950s project that was developed as an alternative to gun launcher-armed vehicles. Its main feature was placement of the whole crew in the tank's turret, which would grant the most protection and reduce the frontal projection area. However, the project was never developed further.
