FV433 Field Artillery, Self-Propelled "Abbot" is the self-propelled artillery variant of the British Army FV430 series of armoured fighting vehicles, using much of the chassis of the FV430 but with a fully rotating turret at the rear housing the 105 mm gun and given the vehicle designation of FV433. Its correct designation was "Gun Equipment 105mm L109 (Abbot)"; L109 was little used, probably to avoid confusion with 155 mm M109 that entered UK service at about the same time.
