Cruiser Mk VIII Challenger
The Tank, Cruiser, Challenger (A30) was a British tank of World War II. It mounted the QF 17-pounder anti-tank gun on a chassis derived from the Cromwell tank to add anti-tank firepower to the cruiser tank units. The design compromises made in fitting the large gun onto the Cromwell chassis resulted in a tank with a powerful weapon and reduced armour. The extemporised 17-pounder Sherman Firefly conversion of the US-supplied Sherman was easier to produce and, with delays in production, only 200 Challengers were built. The Challenger was able to keep up with the fast Cromwell tank and was used with them. History The driving force in the development of the Challenger was William Arthur Robotham. "Roy" Robotham had been a Rolls-Royce executive in the car division who, with no work to do, had led a team to develop a tank powerplant from the Rolls-Royce Merlin aircraft engine. The Rolls-Royce Meteor gave the British a powerful, reliable engine, which was used in the A27M Cruiser M ...

Challenger 1
The FV4030/4 Challenger 1 is a British main battle tank (MBT) used by the British Army from 1983 to 2001, when it was superseded by the Challenger 2. It is also currently used by the Royal Jordanian Army as its main battle tank, after heavy modifications. The variants for the Jordanian military were to be upgraded using the unmanned Falcon turret. History The Challenger design by the former Military Vehicles and Engineering Establishment (MVEE) near Chobham in Surrey originated in an Iranian order for an improved version of the Chieftain line of tanks in service around the world. These were the Chieftain Mk5(P)- FV4030/1, FV4030/2 Shir (Lion) 1 and 4030/3 Shir 2. With the fall of the Shah of Iran and the collapse of the UK MBT-80 project, the British Army became the customer and the tank was further developed by MVEE to meet Western European requirements. For a short time the tank was named "Cheviot" (the name of a hill range) before becoming "Challenger", a name reused fr ...

Challenger 2
The FV4034 Challenger 2 (MOD designation "CR2") is a third generation British main battle tank (MBT) in service with the armies of the United Kingdom and Oman. It was designed and built by the British company Vickers Defence Systems (now known as BAE Systems Land & Armaments). Vickers Defence Systems began to develop a successor to the Challenger 1 as a private venture in 1986. The Ministry of Defence ordered a prototype in December 1988. In June 1991, the MoD placed an order for 140 vehicles, with a further 268 ordered in 1994. Production began in 1993 and the unit's tanks were delivered in July 1994, replacing the Challenger 1. After a production delay, the tank entered service with the British Army in 1998, with the last delivered in 2002. The Challenger 2 was also exported to Oman. 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 than for the Challenger 1 and only around 3% of ...
