The following is a partial listing of FV ("fighting vehicle") numbers as used by the British Army.
Some vehicles do not have FV numbers (e.g. the AS-90).
FV215, Cancelled project for a heavy SPG based on the Conqueror Mk II tank with a 183 mm gun and rear placement of the traversable turret and fighting compartment. The British Army wanted a tank built around the 183 mm gun, one FV 4005 was built as a stopgap before the FV 215 could go into production, but eventually the project was cancelled altogether.
