FV432

The FV432 was designed to be the armoured personnel carrier in the FV430 series. Production started in 1962 by GKN Sankey and ended in 1971, after constructing approximately 3,000 vehicles. The FV432 is of all-steel construction. The chassis is a conventional tracked design with the engine at the front and the driving position to the right. Directly behind the driver's position is the vehicle commander's hatch. There is a large round opening in the passenger compartment roof, which has a split/folding (concertina) hatch, and a (right hand) side-hinged door in the rear for loading and unloading. A 'Boiling Vessel' is mounted on the rear door to provide hot water and heating food. As in many designs of its era, there are no firing ports for the troops carried – British Army doctrine having been for troops to dismount from vehicles to fight, unlike Russian infantry fighting vehicles that largely incorporate ports. The passenger compartment has five seats on either side – these fold up to provide a flat cargo space. An NBC (nuclear, biological, and chemical weapons) system is fitted, normal ventilation provided by a fan mounted in the forward right hand side of the vehicle, air being drawn through a paper element filter (mounted externally on the right hand side of the hull), filtered air being distributed by a duct running around the perimeter of the interior at roof level, extending into the driver's compartment. Provision is made to add carbon filters in case of gas attack, and the system can accommodate heaters and/or air conditioning units. A roof-mounted relief valve allows a constant minimal pressure to be maintained and prevent ingress of foreign matter in the event of blast or alterations in external atmospheric pressure. Wading screens and a trim vane were fitted as standard and an extension provided to elevate the exhaust pipe. The basic vehicle, which could be readied for wading in approximately five minutes, has a water speed of about 6 km/h when converted for swimming and was propelled by its tracks. Most of these vehicles have had their amphibious capability removed. FV432s in service with infantry battalions are equipped with a pintle-mounted L7 GPMG if not fitted with the Peak Engineering turret. Vehicles with the Royal Artillery, Royal Engineers and Royal Signals were originally fitted with the L4A4 variant of the Bren light machine gun, but they now use the GPMG. When equipped with the GPMG, the vehicle carries 1,600 rounds of belted 7.62mm ammunition. When carrying the Bren LMG, the vehicle carried 1,400 rounds of 7.62mm ammunition in 50 magazines, each holding 28 rounds. There are two three-barrel smoke dischargers at the front. The Australian Army evaluated two pre-production FV432s during 1962 and 1963, but decided to purchase M113 armoured personnel carriers instead. The trials undertaken in Queensland demonstrated that the M113's performance was superior to that of the FV432. A number of surplus vehicles were sold to the Indian Army after being withdrawn from UK service. ==Variants==

The FV432 has been produced in three major variants, the Mark 1 (with a Mark 1/1 minor variant) with petrol engines, the Mark 2 with a Rolls-Royce K60 multi-fuel engine and the Mark 3 with a diesel engine. The Mark 2 minor variant, the 2/1, has its NBC pack flush with the hull side. An uparmoured variant, for use in Iraq and Afghanistan, of the Mark 3 was known as Bulldog. This name now appears to be extended to all Mark 3 versions of the FV432. The FV432 has proven to be flexible in use and can be converted from one role to another with reasonable ease using 'installation kits' (IK), or more permanently with minor modifications to the hull. Major or more significant modifications have usually led to a new FV43n number. In addition to the normal armoured personnel carrier role, it has been used as: • a command vehicle, with seven crew, two mapboards and extra communications equipment (with an additional canvas "penthouse") • an ambulance, with spots for up to four stretchers or two stretcher and five seated patients but would not carry any armament other than the smoke dischargers. • a cargo carrier, for up to 3,600 kg • a communications vehicle • a recovery vehicle. Designated as the FV434, it includes a rear cutout to a "pickup-truck" box to carry a spare engine/other stores with tool store below, an internally mounted winch, and a 2.5-tonne lift arm. One of these, of the Royal Hampshires, was driven by their honorary colonel, Diana, Princess of Wales, on her visit to Berlin in 1985 These were later bought by the tank driving and paint-balling company Armourgeddon (who also converted more). These have been modified with a compressed air cylinder on the rear of the turret for the paintball gun. • ZB 298 Elliott Automation Grounds Surveillance Radar • MILAN anti-tank missiles (two missile teams, deployed away from the vehicle) FV432s used by the Royal Artillery have been equipped with: ==Operators==
