The FV4034 Challenger 2 is a British main battle tank (MBT) in service with the armies of the United Kingdom and Oman. It was designed and built by the British companyVickers Defence Systems (now known as BAE Systems Land and Armaments).[5]

The Challenger 2 is an extensive redesign of the Challenger 1. Although the hull and automotive components seem similar, they are of a newer design and build than those of the Challenger 1 and fewer than 5% of components are interchangeable.[6]

The Challenger 2 replaced the Challenger 1 in service with the British Army and is also used by the Royal Army of Oman. It has seen operational service in Bosnia, Kosovo and Iraq.

The Challenger 2 is the third vehicle of this name, the first being the A30 Challenger, a Second World War design using the Cromwell tank chassis with a 17-pounder gun. The second was the Persian Gulf War era Challenger 1, which was the British army's main battle tank (MBT) from the early 1980s to the mid-1990s.

Vickers Defence Systems began to develop a successor to Challenger 1 as a private venture in 1986. Following the issue of a Staff Requirement for a next-generation tank, Vickers formally submitted its plans for Challenger 2 to the Ministry of Defence (MoD). Secretary of State for Defence George Younger announced to the House of Commons that Vickers would receive £90 million contract for a demonstrator vehicle, a deal that was finalised in January 1989.[7] The demonstration phase contained three milestones for progress, with dates of September 1989, March 1990, and September 1990. At the last of these milestones, Vickers was to have met 11 key criteria for the tank's design.[7]

In June 1991, after competition with other tank manufacturers' designs (including the M1A2 Abrams and the Leopard 2 (Improved)), the MoD placed a £520 million order for 127 MBTs and 13 driver training vehicles. An order for a further 259 tanks and 9 driver trainers (worth £800 million) was placed in 1994. Oman ordered 18 Challenger 2s in 1993 and a further 20 tanks in November 1997.

Production began in 1993 at two primary sites: Elswick, Tyne and Wear and Barnbow, Leeds, although over 250 subcontractors were involved. The first tanks were delivered in July 1994.

The Challenger 2 successfully completed its Reliability Growth Trial in 1994. Three vehicles were tested for 285 simulated battlefield days. Each day is known to have consisted of:

  • 27 km (17 mi) of on-road travel
  • 33 km (21 mi) of off-road travel
  • 34 main armament rounds fired
  • 1,000 7.62 MG rounds fired
  • 16 hours weapon system operation
  • 10 hours main engine idling
  • 3.5 hours main engine running

An equally important milestone was the In-Service Reliability Demonstration (ISRD) in 1999. 12 fully crewed tanks were tested at the Bovington test tracks and at LulworthBindon ranges. The tank exceeded all staff requirements.

The Challenger 2 entered service with the British Army in 1998 (with the 2nd Royal Tank Regiment in Germany), with the last delivered in 2002. It is expected to remain in service until 2035. It serves with the Royal Scots Dragoon Guards, the Royal Dragoon Guards, theQueen's Royal Hussars, the King's Royal Hussars and the 2nd Royal Tank Regiment, each of which is the tank unit of an armoured or a mechanised brigade. One squadron of the 1st Royal Tank Regiment uses Challenger 2 in a training and demonstration role. Under Army 2020, only three Challenger 2 Tank Regiments will remain: the King's Royal Hussars, the Queen's Royal Hussars and the combined Royal Tank Regiment and a single Army Reserve regiment providing Armoured Resilience The Royal Wessex Yeomanry.

Deliveries of the Challenger 2 to Oman were completed in 2001.

The Trojan minefield breaching vehicle and the Titan bridge-laying vehicle based on the chassis of the Challenger 2 were shown in November 2006; 66 are to be supplied by BAE Systems to the Royal Engineers, at a cost of £250 million.[8]

A British military document from 2001 indicated that the British Army would not procure a replacement for the Challenger 2 because of a lack of foreseeable conventional threats in the future.[9]
