A project for a tank destroyer based on the Conqueror chassis was developed in the late 1940s. Existed only in blueprints.
The FV 217 "Badger" as it appears in World of Tanks is a combination of the FV 205 and FV 217 proposals - specifically, its model is based on the wooden mock-up that was made of the FV 205, while the name is from the later FV 217. There is little known information on both projects - the FV 205 and FV 217 were intended to be case-mate tank destroyers, based on the chassis of the FV 201 tank. The FV 201 chassis was later used for the FV 221 Caernarvon and the FV 214 Conqueror.
The FV 205 was designed as a "Self-Propelled Medium Anti-Tank gun". A scale model was built in 1947, but the project itself was later cancelled in 1949. The intended armament, as well as the planned armour layout, is unknown. The FV 217 was a later proposal to mount a 120mm cannon into a modified FV 201 chassis, designed as a "Self-Propelled 120 Medium Anti-Tank" vehicle. Like the FV 205, almost nothing is known about the project. Its designation indicates that it was proposed later than the FV 214 Conqueror, possibly due to the complications and delays with the heavy tank. Nevertheless, the FV 217 was also cancelled.
