Lla FV4030/4 Challenger 1 est un char de combat principal britannique (MBT) utilisé par l’armée britannique de 1983 à 2001, date à laquelle il a été remplacé par le Challenger 2. La majorité de la flotte de Challenger 1 a ensuite été vendue à la Jordanie où elle est restée en service dans l’armée royale jordanienne jusqu’à l’annonce des retraits en 2018. Connus localement sous le nom d’Al-Hussein, ces véhicules ont reçu diverses modifications jordaniennes avant d’être remplacés par des chars Leclerc de fabrication française des Émirats arabes unis et des chasseurs de chars à roues B1 Centauro 8×8 de fabrication française. La flotte jordanienne de Challenger 1 avait été retirée en janvier 2023

From Persian Order to British Service
Lla Challenger 1 began its life as the « Shir 2, » a tank intended for the Imperial Iranian Armoured Forces. Following the 1979 Iranian Revolution, the project was taken over by the British Ministry of Defence to replace the aging Chieftain. While it shared the Chieftain’s lethal 120mm rifled gun, the Challenger 1 introduced a revolutionary leap in protection: Chobham Armour. It served as the UK’s primary Main Battle Tank throughout the late Cold War and cemented its legendary status during the Gulf War.

The Chobham Revolution
- Composite Matrix: Unlike previous tanks made of solid steel, the Challenger 1 used Chobham armour, a classified « sandwich » of ceramics and metals. This provided world-leading protection against both Kinetic Energy (KE) rounds and High-Explosive Anti-Tank (HEAT) shaped charges.
- Sloped Turret Design: The turret was characterized by sharp, flat-sloped cheeks designed to maximize the thickness of the Chobham matrix that an incoming shell would have to penetrate.
- Hydrogas Suspension: The Challenger 1 replaced traditional torsion bars with a nitrogen-filled hydropneumatic system. This allowed the 62-ton tank to maintain high speeds over rough terrain while providing a stable platform for the gunner.
The Gulf War Performance
- World Record Sniper: During Operation Granby (1991), a Challenger 1 achieved the longest confirmed tank-to-tank kill in history, destroying an Iraqi T-55 from a distance of 5.1 kilometers (over 3 miles) using an L15 APFSDS round.
- Combat Readiness: Despite early concerns regarding its Fire Control System (FCS) during NATO’s « Canadian Army Trophy » competitions, the Challenger 1 proved exceptionally reliable in the harsh desert, achieving zero losses to enemy fire during the conflict.
- Rifled vs. Smoothbore: British tanks remained unique by sticking with rifled guns. This allowed the use of the HESH (High-Explosive Squash Head) round, which is devastating against bunkers and light structures, though it required two-part ammunition (projectile and charge).
Retirement and Succession
The Challenger 1 was replaced by the Challenger 2 (Challenger 2) in the late 1990s. While they look similar, the Challenger 2 is almost entirely new, with only 5% part commonality. Most retired Challenger 1 tanks were sold to Jordanie, where they served as the « Al-Hussein » MBT until their recent retirement.
