FV433 - ABBOT SPG
It’s History
FV433, 105mm, Field Artillery, Self-Propelled “Abbot” is the self-propelled artillery, or more specifically self-propelled gun (SPG), variant of the British Army FV430 series of armoured fighting vehicles (AFVs), 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.
Development
Designed as a Sexton replacement, its correct designation was “Gun Equipment 105mm L109 (Abbot)”; L109 was little used, probably to avoid confusion with the 155 mm M109 howitzer that entered UK service at about the same time. The name “Abbot” continued the Second World War style of naming self-propelled artillery after ecclesiastical titles. The FV433 used a different configuration of power pack from other vehicles in the FV430 series.
The restoration of Lily
A completely new ammunition family, comprising shells, fuses and cartridges, was designed for Abbot’s L13 gun, designated 105 mm Field (105 mm Fd). Compared to US 105 mm M1 type ammunition, it used electrical instead of percussion primers, and has longer shells. The widely used US M1 type round was called “105 mm How” in UK service.
The Abbot’s maximum speed is approximately 29mph, and has a 240bhp Rolls-Royce K60 multi-fuel opposed piston engine.).
