Chieftan and Merkava:
Development
In December 1974, Iran ordered 125 Shir 1 (FV4030/2) and 1,225 Shir 2 (FV4030/3) MBTs but the order was cancelled by the new Iranian government in July 1979. The first three FV4030/2 prototypes were completed by January 1977.By this time, production of the FV4030/2 was under way at the Royal Ordnance Factory Leeds (which was subsequently taken over by Vickers Defence Systems and now closed down as an AFV production facility) with first production tanks scheduled for delivery in 1980.In November 1979, Jordan placed an order with the UK for 274 Khalid MBTs worth GBP266 million for delivery from 1981.Further development of the Shir 2 (FV4030/3) resulted in the Challenger 1 MBT which entered service with the British Army in 1983 and for which there is a separate entry in Jane's Armoured Fighting Vehicles. The Challenger 1 MBT was withdrawn from service with the British Army late in 2000 and by 2004 just over 400 of these were transferred to Jordan, where they are known as the Al Hussein.Modifications carried out since the Khalid MBT entered service with the Jordanian Army have included modifications of sights and stowage to allow for the carrying and firing of the then RO Defence 120 mm APFSDS-T ammunition and the upgrading of the David Brown Gear Systems TN37 Mk 2 transmission to TN37 Mk 2A standard.Late in 2002, Vickers Defence Systems was taken over by Alvis plc and the company was renamed Alvis Vickers Limited. In late 2004 Alvis plc was taken over
Description
The Khalid is essentially the FV4030/2 MBT with minor modifications to suit Jordanian requirements; it is based on a late production Chieftain with major changes in the fire-control system and new power pack.The power pack consists of the Perkins Engines Company Condor V-12 1200 diesel, the David Brown Gear Systems TN37 transmission and a cooling system by the now AMETEK Aircontrol Technologies.The power packs for the Khalid (FV4030/2) and Challenger 1 are almost identical and both have twin electric starters.The cooling group essentially consists of two air-to-water radiators, two air-cooled charge air coolers and three 380 mm mixed flow fans, mounted on top of the vehicle drive transmission. The Khalid has a bogie-type suspension, which is a further development of that fitted to Chieftain with nearly twice the suspension travel.The fire-control system of the Khalid is the Computer Sighting System, which is similar to the Chieftain Improved Fire-Control System described in the entry for the Chieftain MBT in Jane's Armoured Fighting Vehicles. The Thales (previously Pilkington Optronics) Tank Laser Sight is also fitted to the Khalid.The commander's cupola is a No 15 which was modified to accept the No 84 sight. The No 84 sight was developed by the now Thales and is a combined day/passive night sight plus projector reticle image unit, and provides the commander with a 24 hour vision and firing capability. The No 84 sight incorporates two independent channels for day and night use and interfaces with the then RO Defence 120 mm L11A5 main.
