For much of the Cold War, the British Army's main battle tanks (MBT) were first the Centurion and then the Chieftain. The question of the latter's replacement became urgent when in 1980 MBT80 was canceled. While the Royal Ordnance Challenger (originally the Shir 2) was acquired as a stop gap its design and capability limitations quickly became apparent.Vickers then took over the Royal Ordnance tank building facility and against stiff foreign competition developed the Challenger 2.This superbly researched and illustrated book tells the story of the evolution and subsequent successful career of Challenger 2 which has seen distinguished service in war and peace since 1990 and has proved itself one of the worlds most formidable fighting vehicles. The authors do not shy away from technical detail and make comparisons with competitors. The result is an objective and authoritative work which will delight military equipment buffs, modelers and wargamers.

Challenger 2 (CR2) is the British Army's main battle tank. CR2 is based on the Challenger 1 tank, which served with distinction on operations in the Gulf War and the Balkans. Although a logical development of Challenger 1, CR2 is greatly superior. It is protected by second generation Chobham Armour and features a new digital fire control system that includes a panoramic commander’s sight, a laser range finder and a new version of the Thermal Observation and Gunnery Sight (TOGS II). The turret mounts the high pressure L30 120mm gun that fires conventional APDS-FS, HESH, smoke and depleted uranium projectiles with great accuracy.

The pioneering tank crew of the First World War would be astonished by the advances made in the design of armoured fighting vehicles over the last 100 years which have resulted in the Challenger 2, the current main battle tank in service with the British army. In terms of its speed, manoeuvrability and firepower, and the protection it provides for its crew, the Challenger 2 is one of the most advanced and sophisticated tanks ever built, and it is a popular subject with tank modellers and enthusiasts. That is why this volume in the TankCraft series on the Challenger, featuring hundreds of photographs and specially commissioned colour profiles, is absorbing reading and such a valuable work of reference.Archive photos of the Challenger 2 in service and extensively researched colour profile illustrations depict the tank throughout its operational life. A large part of the book showcases available model kits and aftermarket products, complemented by a gallery of beautifully constructed and painted models in various scales. Technical details as well as modifications introduced during production and in the field are also examined and provide everything the modeller needs to recreate an accurate representation of the Challenger 2.
