Historical reference
A major modernization variant of the standard design for the Charlemagne heavy tank. It was developed in the early 1960s as part of the British GSOR program. The vehicle was equipped with the oscillating turret of the planned GSOR 1008 tank destroyer. The project went no further than blueprints.
