The FV4034 Challenger 2 (MoD designation "CR2") is a <a href="List_of_main_battle_tanks_by_generation#Third" title="List of main battle tanks by generation">third generation</a> British <a href="Main_battle_tank" title="Main battle tank">main battle tank</a> (MBT) in service with the armies of the <a href="British_Army" title="British Army">United Kingdom</a>, <a href="Royal_Army_of_Oman" title="Royal Army of Oman">Oman</a>, and <a href="Armed_Forces_of_Ukraine" title="Armed Forces of Ukraine">Ukraine</a>.<a href="#cite_note-BritishArmy-9">[9]</a><a href="#cite_note-10">[10]</a>

It was designed by <a href="Vickers_Defence_Systems" class="mw-redirect" title="Vickers Defence Systems">Vickers Defence Systems</a> (now Rheinmetall BAE Systems Land (RBSL)) as a private venture in 1986, and was an extensive redesign of the company's earlier <a href="Challenger_1" title="Challenger 1">Challenger 1</a> tank.<a href="#cite_note-BAE-11">[11]</a> The <a href="Ministry_of_Defence_(United_Kingdom)" title="Ministry of Defence (United Kingdom)">Ministry of Defence</a> ordered a prototype in December 1988.

The Challenger 2 has four crew members consisting of a commander, gunner, loader, and driver. The main armament is a <a href="Royal_Ordnance_L30" title="Royal Ordnance L30">L30A1</a> 120-millimetre (4.7 in) rifled tank gun, an improved derivative of the <a href="Royal_Ordnance_L11" title="Royal Ordnance L11">L11 gun</a> used on the <a href="Chieftain_tank" class="mw-redirect" title="Chieftain tank">Chieftain</a> and <a href="Challenger_1" title="Challenger 1">Challenger 1</a>.<a href="#cite_note-janes.com-12">[12]</a> Fifty rounds of ammunition are carried for the main armament, alongside 4,200 rounds of 7.62 mm ammunition for the tank's secondary weapons: a <a href="L94A1" class="mw-redirect" title="L94A1">L94A1</a> EX-34 <a href="Chain_gun" title="Chain gun">chain gun</a> mounted coaxially, and a <a href="FN_MAG" title="FN MAG">L37A2</a> (GPMG) machine gun. The turret and hull are protected with second generation <a href="Chobham_armour" title="Chobham armour">Chobham armour</a>, also known as Dorchester. Powered by a <a href="Perkins_Engines" title="Perkins Engines">Perkins</a> CV12-6A V12 diesel engine, the tank has a range of 550 kilometres (340 mi) and maximum road speed of 59 kilometres per hour (37 mph).<a href="#cite_note-13">[13]</a>

The Challenger 2 eventually completely replaced the <a href="Challenger_1" title="Challenger 1">Challenger 1</a> in British service. In June 1991, the UK ordered 140 vehicles, followed by a further 268 in 1994; these were delivered between 1994 and 2002. The tank entered operational service with the British Army in 1998 and has since been used in <a href="NATO_intervention_in_Bosnia_and_Herzegovina" title="NATO intervention in Bosnia and Herzegovina">Bosnia and Herzegovina</a>, <a href="Kosovo_Force" title="Kosovo Force">Kosovo</a> and <a href="Iraq_War" title="Iraq War">Iraq</a>.<a href="#cite_note-BritishArmy-9">[9]</a> To date, at least five Challenger 2 tanks are confirmed to have been destroyed in operations; the first was by accidental <a href="Friendly_fire" title="Friendly fire">friendly fire</a> from another Challenger 2 in <a href="#Basra_2003">Basra in 2003</a>,<a href="#cite_note-14">[14]</a> and the four others were during the <a href="Russo-Ukrainian_War" title="Russo-Ukrainian War">Russo-Ukrainian War</a>, where the tanks were destroyed under Ukrainian control during the <a href="2023_Ukrainian_counteroffensive" title="2023 Ukrainian counteroffensive">2023 Ukrainian counteroffensive</a> and <a href="Ukrainian_incursion_into_Kursk" class="mw-redirect" title="Ukrainian incursion into Kursk">Ukrainian incursion into Kursk</a>.<a href="#cite_note-15">[note 1]</a><a href="#cite_note-TELUKMBT-16">[15]</a><a href="#cite_note-:0-17">[16]</a>

Challenger 2 tanks were also ordered by <a href="Oman" title="Oman">Oman</a> in the 1990s with delivery of 38 vehicles being completed in 2001. A number of British Challenger 2 tanks were delivered to <a href="Ukraine" title="Ukraine">Ukraine</a> in 2023.<a href="#cite_note-Financial_Times-18">[17]</a>

Since the Challenger 2 entered service in 1998, various upgrades have sought to improve its protection, mobility and lethality. This has culminated in an upgraded design, known as <a href="Challenger_3" title="Challenger 3">Challenger 3</a>, which is set to gradually replace Challenger 2 from 2027.<a href="#cite_note-DIACA-19">[18]</a>

<div class="mw-heading mw-heading2"><h2 id="History">History</h2></div>

<div class="mw-heading mw-heading3"><h3 id="Challenger_1">Challenger 1</h3></div>

The Challenger 2 is the third vehicle of this name, the first being the <a href="Cruiser_Mk_VIII_Challenger" title="Cruiser Mk VIII Challenger">A30 Challenger</a>, a <a href="World_War_II" title="World War II">World War II</a> design using the <a href="Cromwell_tank" title="Cromwell tank">Cromwell tank</a> chassis with a <a href="17-pounder" class="mw-redirect" title="17-pounder">17-pounder</a> gun. The second was the Persian <a href="Gulf_War" title="Gulf War">Gulf War</a> era <a href="Challenger_1" title="Challenger 1">Challenger 1</a>, which was the British army's main battle tank (MBT) from the early 1980s to the mid-1990s.

While the British <a href="Chieftain_(tank)" title="Chieftain (tank)">Chieftain</a> was heavily armed and armoured, its engine and suspension were considerably subpar compared to its contemporaries, leading to poor cross-country performance and a lack of maneuverability.

Some work on further development of the Chieftain had been ongoing since 1968 at the <a href="Military_Vehicles_and_Engineering_Establishment" title="Military Vehicles and Engineering Establishment">Military Vehicles and Engineering Establishment</a> (MVEE), and several experimental vehicles produced, including one with the recently developed <a href="Chobham_armour" title="Chobham armour">Chobham armour</a>. In September 1978, it was announced that these concepts would be brought together in a new design, <a href="MBT-80" title="MBT-80">MBT-80</a>. Deliveries of the MBT-80 were not expected until the mid-1980s at a minimum. Advances in Soviet armor, especially the apparent upcoming introduction of the <a href="T-80" title="T-80">T-80</a>, suggested that the UK's tanks would be at a significant disadvantage before the MBT-80 would arrive. After considerable debate, MBT-80 was cancelled. Instead, in 1978, the British Army ordered the Challenger 1, based on the <a href="Shir_2" class="mw-redirect" title="Shir 2">Shir 2</a>. The final Challenger 1 was delivered to the British Army in 1990.<a href="#cite_note-20">[19]</a>

<div class="mw-heading mw-heading3"><h3 id="Challenger_2_contest">Challenger 2 contest</h3></div>

As Challenger production ramped up the government was interested in marketing it to its traditional customers like <a href="Jordan" title="Jordan">Jordan</a>. To improve its sales prospects, the tank was entered in the 1987 running of the <a href="Canadian_Army_Trophy" title="Canadian Army Trophy">Canadian Army Trophy</a> for tank performance, which had historically been won many times by <a href="British_Army" title="British Army">British Army</a> or <a href="Canadian_Army" title="Canadian Army">Canadian Army</a> units in British tanks. In this run, however, the Challenger performed very poorly, with its units ending up at the bottom of the rankings. While this performance was dismissed by the Ministry of Defense, including in comments in the <a href="House_of_Commons" title="House of Commons">House of Commons</a>, it was a serious blow to its sales prospects. It also proved only marginally more reliable than the Chieftain, which was considered unreliable and a maintenance problem in the field, and the lack of significant improvement was much to the annoyance of the <a href="British_Army" title="British Army">British Army</a>.<a href="#cite_note-wrong-21">[20]</a>

Vickers began considering improvements under the Improved Challenger name in November 1986. They presented their work to the <a href="Ministry_of_Defence_(United_Kingdom)" title="Ministry of Defence (United Kingdom)">Ministry of Defence</a> (MoD) in March 1987. In February 1988, the MoD issued Staff Requirement 4026, or the Chieftain Replacement Programme, which called for a new design to replace those Chieftains still in service. This program compared the American Abrams (as the XM1 was now known), French <a href="Leclerc_tank" title="Leclerc tank">Leclerc</a> and German <a href="Leopard_2" title="Leopard 2">Leopard 2</a>, as well as Vickers's Improved Challenger. Initial studies by the <a href="British_Army" title="British Army">British Army</a> invariably selected the Leopard 2, which was protected as well as Challenger but had much better mobility and used the smoothbore 120 mm gun that would give it commonality with other <a href="NATO" title="NATO">NATO</a> forces. The second choice was the Abrams, in second due largely to concerns with its fuel use.<a href="#cite_note-wrong-21">[20]</a>

After some supportive lobbying by <a href="David_Young%2C_Baron_Young_of_Graffham" title="David Young, Baron Young of Graffham">Baron Young</a>, the <a href="Third_Thatcher_ministry" title="Third Thatcher ministry">Thatcher government</a> chose to proceed with the Vickers entry in December 1988, giving it the official name Challenger 2.<a href="#cite_note-Abrams_evaluation-22">[21]</a>

<div class="mw-heading mw-heading3"><h3 id="Prototypes">Prototypes</h3></div>

Vickers received a £90 million contract for a demonstrator vehicle to be delivered by September 1990. Part of this proof-of-concept phase was the demonstration that a <a href="Depleted_uranium" title="Depleted uranium">depleted uranium</a> projectile and more powerful gunpowder charge could be developed for the updated "CHARM" 120 mm gun developed at Royal Ordinance, which would give it capability against the latest Soviet designs.<a href="#cite_note-Simon_Dunstan_page_5-23">[22]</a><a href="#cite_note-Abrams_evaluation-22">[21]</a> The demonstration phase had 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.<a href="#cite_note-Simon_Dunstan_page_5-23">[22]</a>

The demonstration phase was generally successful; the major design was completed by August 1989, and production of a series of nine prototypes began. These were largely complete August 1990, and the program as a whole considered successfully completed on time in September. By this point, the <a href="Gulf_War" title="Gulf War">Gulf War</a> had started and Challenger 1 was sent to <a href="Iraq" title="Iraq">Iraq</a>, where it performed far better than its initial showing would suggest, including performing several very long range kills against Iraqi armor, including one at over 5 kilometres (3.1 mi) range. This performance bolstered the MoD's confidence in British armour.<a href="#cite_note-leclerc-24">[23]</a>

<div class="mw-heading mw-heading3"><h3 id="Production_and_delivery">Production and delivery</h3></div>

In June 1991 the decision to buy Challenger 2 was made formal with a £520 million contract for 127 tanks and 13 driver training tanks.<a href="#cite_note-leclerc-24">[23]</a> Production began in 1993 at two primary sites (<a href="Elswick%2C_Tyne_and_Wear" class="mw-redirect" title="Elswick, Tyne and Wear">Elswick, Tyne and Wear</a>; and <a href="Barnbow" title="Barnbow">Barnbow</a>, <a href="Leeds" title="Leeds">Leeds</a>) with over 250 subcontractors involved. It was formally accepted on 16 May 1994 with the first tanks delivered in July 1994. An order for a further 259 tanks and 9 driver trainers worth £800 million was placed in July. The Challenger 2 failed its acceptance trials in 1994, and it was forced into the Progressive Reliability Growth Trial in 1995. Three vehicles were tested for 285 simulated battlefield days.

Due to downsizing of the Army after the end of the <a href="Cold_War" title="Cold War">Cold War</a>, the two runs of Challenger 2 would result in enough tanks to arm the entire Army, as opposed to the mixture of Challenger 1 and 2 that was formerly planned. This made the Challenger 1 surplus, and these were eventually shipped to Jordan for free. Vickers struggled to market the tank for export.<a href="#cite_note-25">[24]</a> Its one success led to Oman ordering 38 Challenger 2s; 18 in June 1993<a href="#cite_note-Oman_1993-26">[25]</a> and a further 20 in November 1997.<a href="#cite_note-27">[26]</a> Both batches ordered by Oman contain notable differences from the UK version: a larger cooling group and rear <a href="Towing_eyes" class="mw-redirect" title="Towing eyes">towing eyes</a>, running gear and bazooka plates similar to Challenger 1, and a loader's <a href="M2_Browning" title="M2 Browning">Browning 0.5 Calibre M2 Heavy Machine Gun</a>. Deliveries of Challenger 2 to Oman were completed in 2001.

The tank was then accepted into service in 1998. An equally important milestone was the In-Service Reliability Demonstration (ISRD) in 1998. The CR2 In-Service Reliability Demonstration (ISRD) milestone was successfully achieved in January 1999. The ISRD took place from September to December 1998. Twelve fully crewed tanks were tested at the <a href="Bovington" class="mw-redirect" title="Bovington">Bovington</a> test tracks and the <a href="Lulworth" title="Lulworth">Lulworth</a> Bindon ranges. The tank exceeded all staff requirements.

<div class="mw-heading mw-heading3"><h3 id="Later_developments_and_possible_replacement">Later developments and possible replacement</h3></div>

The Challenger 2 entered service with the Royal Scots Dragoon Guards, with the last delivered in 2002. After the <a href="Army_2020" title="Army 2020">Army 2020</a> restructuring, only three Challenger 2 Tank Regiments will remain: the <a href="Queen's_Royal_Hussars" title="Queen's Royal Hussars">Queen's Royal Hussars</a>, the King's Royal Hussars and the <a href="Royal_Tank_Regiment" title="Royal Tank Regiment">Royal Tank Regiment</a>, each of which is the tank regiment of an Armoured Infantry Brigade. A single <a href="Army_Reserve_(United_Kingdom)" title="Army Reserve (United Kingdom)">Army Reserve</a> regiment, <a href="The_Royal_Wessex_Yeomanry" class="mw-redirect" title="The Royal Wessex Yeomanry">The Royal Wessex Yeomanry</a>, will provide reservist Challenger crews to the regular regiments.

Sixty-six are to be supplied by BAE Systems to the <a href="Royal_Engineers" title="Royal Engineers">Royal Engineers</a>, at a cost of £250 million.<a href="#cite_note-28">[27]</a>

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.<a href="#cite_note-Challenger_2_last-29">[28]</a> However, <a href="IHS_Jane's_360" class="mw-redirect" title="IHS Jane's 360">IHS Jane's 360</a> reported in September 2015 that following discussions with senior Army officers and procurement officials at DSEI 2015 and the head of the British Army, <a href="Nick_Carter_(British_Army_officer)" title="Nick Carter (British Army officer)">General Sir Nick Carter</a>, that the British Army was looking at either upgrading the Challenger 2 or outright replacing it. Sources confirmed that the future of the MBT was being considered at the highest levels of the Army.<a href="#cite_note-janes-30">[29]</a>

This stemmed from the British Army's concern with the new Russian <a href="T-14_Armata" title="T-14 Armata">T-14 Armata</a> main battle tank and the growing ineffectiveness of the ageing L30 rifled gun and the limited types of ammunition supported. It was confirmed that numerous armoured vehicle manufacturers had discussions with the MoD about a potential replacement for the Challenger 2.<a href="#cite_note-janes-30">[29]</a> Shortly after, the British Army decided that purchasing a new tank would be too expensive and chose to proceed with the Challenger 2 Life Extension Project (LEP).<a href="#cite_note-31">[30]</a> The Challenger 2 is expected to remain in service until 2025.<a href="#cite_note-32">[31]</a>

Between 2010 and 2014, 43 Challenger 2 tanks were disposed of as "beyond any economic repair".<a href="#cite_note-times-20230730-33">[32]</a>

The maintenance contract <a href="Rheinmetall_BAE_Systems_Land#Challenger_2_Life_Extension_Project_(C2_LEP)" title="Rheinmetall BAE Systems Land">was let sometime in 2021</a>.

As of 2022 maintenance and overhaul of the Challenger 2 is undertaken by the <a href="Babcock_Defence_Support_Group" class="mw-redirect" title="Babcock Defence Support Group">Babcock Defence Support Group</a>.

The initial operating capability for the upgraded <a href="Challenger_3" title="Challenger 3">Challenger 3</a> tanks is expected by 2027.<a href="#cite_note-dnci-35">[34]</a>

In May 2021, the UK MoD published a <a href="Command_paper" title="Command paper">command paper</a> entitled <a href="Defence_in_a_Competitive_Age" title="Defence in a Competitive Age">Defence in a Competitive Age</a>.

After the <a href="Russian_invasion_of_Ukraine" title="Russian invasion of Ukraine">Russian invasion of Ukraine</a> in 2022, the then British Prime Minister, <a href="Boris_Johnson" title="Boris Johnson">Boris Johnson</a>, declined Ukrainian requests for Challenger 2 tanks to be part of the military aid packages arranged by the United Kingdom and other NATO countries. British <a href="Secretary_of_State_for_Defence" title="Secretary of State for Defence">Defence Secretary</a> <a href="Ben_Wallace_(politician)" title="Ben Wallace (politician)">Ben Wallace</a> had said that the idea "wouldn't work".<a href="#cite_note-eatb-37">[36]</a> In April 2022, Johnson and his German counterpart <a href="Olaf_Scholz" title="Olaf Scholz">Olaf Scholz</a> stated that both Western European allies would withhold their MBTs from the war. Johnson instead chose to deploy British Challenger 2 tanks to Poland to backfill the Polish Army and allowing the Polish government to donate Soviet-era <a href="T-72" title="T-72">T-72s</a> to Ukraine.<a href="#cite_note-pcg-38">[37]</a><a href="#cite_note-dmbg-39">[38]</a>

On 14 January 2023, the British government confirmed reports that in light of the developing situation in Ukraine, it had reversed its position on the supply of Challenger 2 tanks to Ukraine. An initial commitment of 14 vehicles was announced, alongside 30 <a href="AS-90" title="AS-90">AS-90</a> 155 mm self-propelled guns, and armoured repair and recovery vehicles. A spokesperson for the British Prime Minister, <a href="Rishi_Sunak" title="Rishi Sunak">Rishi Sunak</a>, described the move as reflecting "the UK's ambition to intensify support". These tanks were the first Western MBTs offered to Ukraine, supplementing donations of Western manufactured infantry fighting vehicles, armoured personnel carriers, and self-propelled artillery;<a href="#cite_note-40">[39]</a><a href="#cite_note-41">[40]</a><a href="#cite_note-bbc.co.uk-42">[41]</a> A number of other countries have subsequently announced that they would supply Ukraine with Western-manufactured MBTs; specifically the American <a href="M1_Abrams" title="M1 Abrams">M1 Abrams</a> and German-made <a href="Leopard_1" title="Leopard 1">Leopard 1</a> and <a href="Leopard_2" title="Leopard 2">Leopard 2</a>.<a href="#cite_note-43">[42]</a>

On 29 January 2023, the UK Ministry of Defence announced that the first Ukrainian troops had arrived in the UK to begin training on Challenger 2.<a href="#cite_note-BFBS-44">[43]</a> On 8 February, Sunak and Ukrainian President <a href="Volodymyr_Zelenskyy" title="Volodymyr Zelenskyy">Volodymyr Zelenskyy</a> paid a visit to Ukrainian soldiers at <a href="Lulworth_Camp" title="Lulworth Camp">Lulworth Camp</a> where they were being trained on Challenger 2 tanks by British soldiers from the <a href="Royal_Tank_Regiment" title="Royal Tank Regiment">Royal Tank Regiment</a> and the <a href="Queen's_Royal_Hussars" title="Queen's Royal Hussars">Queen's Royal Hussars</a>. Sunak used the opportunity to reaffirm the British intention to have the first Challenger 2 tanks delivered to Ukraine by March 2023.<a href="#cite_note-45">[44]</a>

On 27 March 2023, the UK Ministry of Defence announced that Ukrainian tank crews had completed their training in the UK on Challenger 2 tanks, and had returned to Ukraine.<a href="#cite_note-46">[45]</a>

On 18 August 2023 a picture of a Challenger 2 in Ukraine was released on Twitter. Unique modifications include top-mounted <a href="Slat_armour" class="mw-redirect" title="Slat armour">slat armour</a> believed to be used to stop drone attacks.<a href="#cite_note-47">[46]</a>

On 4 September 2023, a video emerged from <a href="Robotyne" title="Robotyne">Robotyne</a> which showed the first combat loss of the Challenger 2 tank.<a href="#cite_note-TELUKMBT-16">[15]</a><a href="#cite_note-destroyedchallenger-48">[47]</a>

During the <a href="Ukrainian_incursion_into_Kursk" class="mw-redirect" title="Ukrainian incursion into Kursk">Ukrainian incursion into Kursk</a>, three more Challenger 2 tanks were visually confirmed to have been destroyed.<a href="#cite_note-auto4-49">[48]</a><a href="#cite_note-50">[49]</a>

<div class="mw-heading mw-heading2"><h2 id="Design">Design</h2></div>

<div class="mw-heading mw-heading3"><h3 id="Armament">Armament</h3></div>

The Challenger 2 is equipped with a 120-millimetre (4.7 in) 55-<a href="Caliber_(artillery)" title="Caliber (artillery)">calibre</a> long <a href="Royal_Ordnance_L30" title="Royal Ordnance L30">L30A1</a> tank gun,<a href="#cite_note-janes.com-12">[12]</a> the successor to the L11 gun used on <a href="Chieftain_tank" class="mw-redirect" title="Chieftain tank">Chieftain</a> and Challenger 1. The gun is made from high strength <a href="Electro-slag_remelting" title="Electro-slag remelting">electro-slag remelting</a> (ESR) steel with a chromium alloy lining. Like earlier British 120 mm guns, it is insulated by a <a href="Thermal_sleeve" title="Thermal sleeve">thermal sleeve</a>. It is fitted with a muzzle reference system and <a href="Fume_extractor" class="mw-redirect" title="Fume extractor">fume extractor</a>, and is controlled by an all-electric control and stabilisation system. The turret has a rotation time of 9 seconds through 360 degrees.

Uniquely among <a href="NATO" title="NATO">NATO</a> main battle tank guns, the L30A1 is <a href="Rifled" class="mw-redirect" title="Rifled">rifled</a> and along with its predecessor, the <a href="Royal_Ordnance_L11A5" class="mw-redirect" title="Royal Ordnance L11A5">Royal Ordnance L11A5</a>, the only Third Generation Main Battle Tank Guns to use a rifled barrel. This is because the British Army continues to place a premium on the use of <a href="High_explosive_squash_head" class="mw-redirect" title="High explosive squash head">high explosive squash head</a> (HESH) rounds in addition to <a href="Armour-piercing_fin-stabilized_discarding-sabot" class="mw-redirect" title="Armour-piercing fin-stabilized discarding-sabot">armour-piercing fin-stabilized discarding-sabot</a> (APFSDS) rounds. HESH rounds have a longer range (up to 8 kilometres or 5 miles further) than APFSDS, and are more effective against buildings and thin-skinned vehicles.<a href="#cite_note-51">[50]</a>

Forty-nine main armament rounds are carried in the turret and hull. These are a mix of L27A1 APFSDS (also referred to as CHARM 3), L31 HESH and L34 <a href="White_phosphorus" title="White phosphorus">white phosphorus</a> smoke rounds, depending on the situation. As with earlier versions of the 120 mm gun, the propellant charges are loaded separately from the shell or KE projectile. A combustible rigid charge is used for the APFSDS rounds and a combustible hemicylindrical bag charge for the HESH and smoke rounds. An electrically fired vent tube is used to initiate firing of the main armament rounds. The main armament ammunition is described to be "three-part ammunition", consisting of the projectile, charge and vent tube. The separation of ammunition pieces aids in ensuring lower chances of unfired <a href="Cooking_off" title="Cooking off">ammunition detonating prematurely</a>.

The Challenger 2 is also armed with a <a href="L94A1" class="mw-redirect" title="L94A1">L94A1</a> EX-34 7.62 mm <a href="Chain_gun" title="Chain gun">chain gun</a> coaxially to the left of the main gun, and a 7.62 mm <a href="L7_(machine_gun)" class="mw-redirect" title="L7 (machine gun)">L37A2</a> (GPMG) machine gun mounted on a pintle on the loader's hatch ring; 4,200 rounds of 7.62 mm ammunition are carried. The Challenger can also mount a Leonardo "Enforcer" <a href="Remote_controlled_weapon_station" title="Remote controlled weapon station">remote control weapons system</a>, bearing a 7.62 mm <a href="L7_(machine_gun)" class="mw-redirect" title="L7 (machine gun)">L37A2</a> (GPMG) machine gun, a 12.7 mm heavy machine gun or a 40 mm automatic grenade launcher.<a href="#cite_note-52">[51]</a>

The driver's position is equipped with a Thales Optronics image-intensifying Passive Driving Periscope (PDP) for night driving and a rear view thermal camera.

<div class="mw-heading mw-heading3"><h3 id="Protection">Protection</h3></div>

The Challenger 2 is a heavily armoured and well protected tank.<a href="#cite_note-Fprado-53">[52]</a> The turret and hull are protected by second-generation <a href="Chobham_armour" title="Chobham armour">Chobham armour</a>, also known as Dorchester, the details of which are classified but which is said to have a mass efficiency more than twice that of <a href="Rolled_homogeneous_armour" title="Rolled homogeneous armour">rolled homogeneous armour</a> against <a href="High-explosive_anti-tank" title="High-explosive anti-tank">high-explosive anti-tank</a> (HEAT) projectiles. Crew safety was paramount in the design. It uses a <a href="Solid-state_electronics" title="Solid-state electronics">solid state electric drive</a> for turret and gun motion, instead of hydraulic systems that can leak fluid into the crew compartment.

<a href="Explosive_reactive_armour" class="mw-redirect" title="Explosive reactive armour">Explosive reactive armour</a> kits and additional <a href="Bar_armour" class="mw-redirect" title="Bar armour">bar armour</a> may be fitted as needed. The nuclear, biological, and chemical (NBC) protection system is located in the turret bustle. The tank's shape is designed to minimise its radar signature. On each side of the turret are five L8 <a href="Smoke_grenade" title="Smoke grenade">smoke grenade</a> dischargers. The Challenger 2 can create smoke by injecting diesel fuel into the exhaust manifolds.

<div class="mw-heading mw-heading3"><h3 id="Drive_system">Drive system</h3></div>

The tank's drive system comprises:

<ul><li>Engine: <a href="Perkins_Engines" title="Perkins Engines">Perkins</a> 26.1 litre, 60° vee, twin turbocharged, CV12-6A four-stroke, four-valve-per-cylinder (pushrod), direct-injection <a href="Diesel_engine" title="Diesel engine">diesel engine</a> delivering 1,200 bhp (890 kW) at 2300 rpm. Torque 4126 Nm at 1700 rpm.<a href="#cite_note-54">[53]</a> The engine and gearbox are controlled by a Petards Vehicle Integrated Control System (VICS).<a href="#cite_note-55">[54]</a></li>

<li>Gearbox: <a href="David_Brown_Limited" class="mw-redirect" title="David Brown Limited">David Brown</a> Santasalo TN54E epicyclical transmission (6 fwd, 2 rev.) rated at 1200 bhp and upgradable to 1500 bhp.<a href="#cite_note-56">[55]</a></li>

<li>Suspension: Horstman Defence Systems second-generation <a href="Hydropneumatic_suspension" title="Hydropneumatic suspension">hydrogas</a> suspension units (HSU).</li>

<li>Track: William Cook Defence hydraulically adjustable TR60 414FS double-pin.<a href="#cite_note-57">[56]</a></li>

<li>Maximum speed: 37 mph (60 km/h) on road; 25 mph (40 km/h) cross country</li>

<li>Range: 342 mi or 550 km on road with external fuel; 156 mi (250 km) cross country on internal fuel.</li></ul>

The tank is fitted with an Extel Systems Wedel auxiliary power unit, an APU, also referred to as a generating unit engine (GUE), based on a 38 kW Perkins P404C-22 diesel engine. It has a 600 A electrical output, which can be used to power the vehicle's electrical systems when it is stationary and the main engine is switched off. This replaces the Perkins P4.108 engine fitted when the tank was first introduced.<a href="#cite_note-58">[57]</a> The use of an APU allows fuel consumption to be reduced, and lowers the audio and thermal signature of the vehicle.

By 2013 the British Army had, at various events featuring the Challenger 2, begun to state the on-road range as 550 km as opposed to an earlier stated value of 450 km.<a href="#cite_note-youtube.com-7">[7]</a> They also publicly stated a maximum road speed of 59 km/h while equipped with 15 tons of additional modules.<a href="#cite_note-youtube.com-7">[7]</a>

<div class="mw-heading mw-heading3"><h3 id="Crew_and_accommodation">Crew and accommodation</h3></div>

The British Army maintained its requirement for a four-man crew, including a loader, after risk analysis of the incorporation of an <a href="Autoloader" title="Autoloader">automatic loader</a> suggested that autoloaders reduced battlefield survivability. Mechanical failure and the time required for repair were prime concerns.

Similar to every British tank since the <a href="Centurion_tank" class="mw-redirect" title="Centurion tank">Centurion</a>, and most other British AFVs, Challenger 2 contains a <a href="Boiling_vessel" title="Boiling vessel">boiling vessel</a> (BV) for water, for use preparing and heating food and drink.<a href="#cite_note-59">[58]</a>

<div class="mw-heading mw-heading3"><h3 id="Peacekeeping_in_the_Balkans">Peacekeeping in the Balkans</h3></div>

The first operational deployments of Challenger 2 tanks were to support <a href="United_Nations_Mission_in_Bosnia_and_Herzegovina" title="United Nations Mission in Bosnia and Herzegovina">peacekeeping operations in Bosnia and Herzegovina</a> and <a href="Kosovo" title="Kosovo">Kosovo</a>.

Challenger 2 was first used in combat in March 2003 during the <a href="Invasion_of_Iraq" class="mw-redirect" title="Invasion of Iraq">invasion of Iraq</a>. The 120 tanks of <a href="7th_Armoured_Brigade_(United_Kingdom)" title="7th Armoured Brigade (United Kingdom)">7th Armoured Brigade</a>, part of <a href="1st_(United_Kingdom)_Division" class="mw-redirect" title="1st (United Kingdom) Division">1st Armoured Division</a>, went into action around <a href="Basra" title="Basra">Basra</a>. The type saw extensive use during the siege of the city, providing fire support to the British forces and knocking out Iraqi tanks, mainly <a href="T-54/55" class="mw-redirect" title="T-54/55">T-54/55s</a>.

The tanks deployed to Iraq were "desertised" in an effort to avoid the difficulties that had been identified in Challenger 2 during <a href="Saif_Sareea_II" class="mw-redirect" title="Saif Sareea II">Exercise Saif Sareea II</a> in <a href="Oman" title="Oman">Oman</a> 18 months earlier. The addition of sand filters and other modifications through a series of Urgent Operational Requirements substantially improved the platform's <a href="Operational_availability" title="Operational availability">operational availability</a>.

During the <a href="2003_invasion_of_Iraq" title="2003 invasion of Iraq">2003 invasion of Iraq</a>, the Challenger 2 tanks suffered no tank losses to Iraqi fire. In one encounter within an urban area, a Challenger 2 came under attack from irregular forces with machine guns and <a href="Rocket_propelled_grenade" class="mw-redirect" title="Rocket propelled grenade">rocket propelled grenades</a> (RPGs). The driver's sight was damaged and while attempting to back away under the commander's directions, the other sights were damaged and the tank threw its tracks entering a ditch.<a href="#cite_note-61">[60]</a> The crew survived, safe within the tank until it was recovered for repairs, the worst damage being to the sighting system. It was back in operation six hours later.

<ul><li>25 March 2003: A <a href="Friendly_fire" title="Friendly fire">friendly fire</a> ("blue-on-blue") incident in Basra in which one Challenger 2 of the Black Watch Battlegroup (<a href="2nd_Royal_Tank_Regiment" title="2nd Royal Tank Regiment">2nd Royal Tank Regiment</a>) mistakenly engaged another Challenger 2 of the <a href="Queen's_Royal_Lancers" title="Queen's Royal Lancers">Queen's Royal Lancers</a> after detecting what was believed to be an enemy flanking manoeuvre on thermal equipment. The attacking tank's second HESH round hit the open commander's hatch lid of the QRL tank sending hot fragments into the turret, killing two crew members. The hit caused a fire that eventually ignited the stowed ammunition, destroying the tank. This was the first Challenger 2 to be destroyed on operations.<a href="#cite_note-62">[61]</a><a href="#cite_note-63">[62]</a><a href="#cite_note-64">[63]</a></li>

<div class="mw-heading mw-heading3"><h3 id="Russian_invasion_of_Ukraine">Russian invasion of Ukraine</h3></div>

In July 2022, a squadron of 14 Challenger 2 tanks of the <a href="Queen's_Royal_Hussars" title="Queen's Royal Hussars">Queen's Royal Hussars</a> were sent to <a href="Poland" title="Poland">Poland</a> on an initial 6-month deployment. The squadron is to be integrated into a Polish battlegroup under Polish command. The move is designed to 'backfill' Polish capability after Polish <a href="T-72" title="T-72">T-72</a> tanks were <a href="List_of_military_aid_to_Ukraine_during_the_Russo-Ukrainian_War" title="List of military aid to Ukraine during the Russo-Ukrainian War">donated to Ukraine</a>.<a href="#cite_note-72">[71]</a>

On 21 June 2023, the Ukrainian army released a video purportedly showing the Challenger 2 in Ukraine. The tanks are assigned to the 11th Separate Army Aviation although this may be a deception move.<a href="#cite_note-73">[72]</a> In September 2023, Ukrainian Air Assault Forces Command published a video interview with a Ukrainian Challenger 2 crew member who stated that the tank was a "sniper rifle among tanks" due to its accuracy.<a href="#cite_note-ukraineinterview-74">[73]</a>

On 4 September 2023, a video emerged from Robotyne which showed the first combat loss of a Challenger 2 tank.<a href="#cite_note-destroyedchallenger-48">[47]</a> A <a href="9M133_Kornet" title="9M133 Kornet">9M133 Kornet</a> missile triggered a fire that apparently cooked off the Challenger 2's ammunition charges, and the resulting blast wrenched the Challenger 2's <a href="Jack-in-the-box_effect" title="Jack-in-the-box effect">turret from its hull</a>.<a href="#cite_note-75">[74]</a>

According to Ukrainian media in 10 March 2024: two more Challenger 2s had been damaged and repaired; only 7 of 14 remain in combat-ready condition. It is often necessary to repair turret parts and the aiming system; the low level of readiness is due to delays getting parts for routine repairs.<a href="#cite_note-Unews-76">[75]</a> One Ukrainian Challenger 2 crew member said that the tank's 1,200-horsepower engine is under-powered for a 71-ton vehicle, and they often get bogged down in soft soil and need towing by other Challengers or engineering vehicles. While a smoothbore 120 mm L44 tank cannon has a useful life of up to 1,500 rounds, a rifled L30A1 wears out after only 500 rounds.<a href="#cite_note-77">[76]</a>

The Challenger Lethality Improvement Programme (CLIP) was a programme to replace the current L30A1 rifled gun with the smoothbore <a href="Rheinmetall_120_mm_gun" class="mw-redirect" title="Rheinmetall 120 mm gun">Rheinmetall 120 mm gun</a> currently used in the <a href="Leopard_2" title="Leopard 2">Leopard 2</a> and <a href="M1_Abrams" title="M1 Abrams">M1 Abrams</a>. The use of a smoothbore weapon would have allowed Challenger 2 to use NATO standard ammunition, including tungsten-based <a href="Kinetic_energy_penetrator" title="Kinetic energy penetrator">kinetic energy penetrators</a> which do not have the same political and environmental objections as <a href="Depleted_uranium" title="Depleted uranium">depleted uranium</a> rounds. The production lines for rifled 120 mm ammunition in the UK have been closed for some years so existing stocks of ammunition for the L30A1 are finite.<a href="#cite_note-forecastinternational-83">[82]</a>

A single Challenger 2 was fitted with the L55 and underwent trials in January 2006.<a href="#cite_note-84">[83]</a> The smoothbore gun was the same length as the L30A1 and was fitted with the rifled gun's cradle, thermal sleeve, bore evacuator and muzzle reference system. Early trials apparently revealed that the German tungsten DM53 round was more effective than the depleted uranium CHARM 3.<a href="#cite_note-Fprado-53">[52]</a> The ammunition storage and handling arrangements had to be changed to cater for the single-piece smoothbore rounds, instead of the separate-loading rifled rounds. Other improvements were also considered, including a regenerative <a href="CBRN_defense" title="CBRN defense">NBC</a> protection system.<a href="#cite_note-85">[84]</a>

<div class="mw-heading mw-heading3"><h3 id="HAAIP">HAAIP</h3></div>

Updates to the automotive components of Challenger 2 are being undertaken as part of the ongoing Heavy Armour Automotive Improvement Programme (HAAIP), which is expected to continue until 2031, and expected to align with the Challenger 3 programme.<a href="#cite_note-DVD_2018:_BAE_Systems'_Challenger_2_demonstrator_-_Black_Night-86">[85]</a><a href="#cite_note-The_Procurement_Of_HAAIP_Main_Engine_Cooling_Fans_–_Annex_A-87">[86]</a> The HAAIP programme "will be made to existing in-service Challenger 2 tanks to increase their mobility and stability, both of which are critical to providing the foundation for the new turret and systems that will upgrade the vehicle to a Challenger 3."<a href="#cite_note-amu-34">[33]</a>

HAAIP has already led to upgrades to the air filtration system, through the use of cleanable air filters with increased operating life, which were tested in <a href="Exercise_Saif_Sareea_3" class="mw-redirect" title="Exercise Saif Sareea 3">Exercise Saif Sareea 3</a> in October 2018.<a href="#cite_note-auto-88">[87]</a> The HAAIP programme, awarded to BAE Systems, was intended to apply a common engine and suspension standard to Challenger 2, the DTT, <a href="Challenger_1#CRAARV" title="Challenger 1">CRARRV</a>, Titan and Trojan, improving reliability.<a href="#cite_note-Armoured_Fighting_Vehicles:Written_question_-_HL271-89">[88]</a> However the Minister of State for Defence announced in April 2022 that a common engine (build standard) will be applied to Challenger 2, Challenger 3 and CRARRV only after a new refrigerant is found for the CTCS (Crew Temperature Control System).<a href="#cite_note-Challenger_Tanks:_Engines_(Qs.2)-90">[89]</a>

In terms of the powertrain, BAE Systems were evaluating whether to uprate the existing CV12 engine or swap this for alternative designs. The proposed CV12 upgrade by <a href="Caterpillar_Inc.#Caterpillar_Defense_Products" title="Caterpillar Inc.">Caterpillar Defense</a> would fit electronically controlled common rail fuel injection and introduce engine health monitoring (HUMS). This would increase the maximum power output from 1,200 bhp (at 2,300 rpm) to 1,500 bhp (at 2,400 rpm), reduce battlefield smoke emissions, and improve fleet reliability and availability.<a href="#cite_note-CV12_Military_Engine-91">[90]</a><a href="#cite_note-Caterpillar_Defense_Vehicle_Engines_and_Future_Plans_(IAV_2019)-92">[91]</a> Since this information was released (February 2019) no further information in the public domain has been released regarding fitting Common Rail Fuel Injection and HUMS. The engines and transmission units have themselves also been remanufactured in recent years, with parts and equipment also purchased to convert CV12-6A engines to CV12-8A build standard.<a href="#cite_note-United_Kingdom-Bristol:_Repair_and_maintenance_services_of_military_vehicles,_2014/S_172-305466-93">[92]</a><a href="#cite_note-United_Kingdom-Telford:_Repair_and_maintenance_services_of_vehicle_transmissions,_2018/S_138-316646-94">[93]</a><a href="#cite_note-United_Kingdom-Telford:_Repair,_maintenance_and_associated_services_of_vehicles_and_related_equipment,_2020/S_034-081842-95">[94]</a> Publications in support of tender procurement for HAAIP indicate that a new CV12-9A engine build standard will be used for the Challenger 2s upgraded to become Challenger 3s, and for CRARRV.<a href="#cite_note-The_Procurement_Of_HAAIP_Main_Engine_Cooling_Fans_–_Annex_F-96">[95]</a>

Work to update the base Challenger 2 hull and automotive components, undertaken by DE&S, RBSL and Babcock, commenced in July 2021 in advance of these being converted to Challenger 3s. Equipment replaced during HAAIP will be checked for serviceability, repaired if required, and returned for re-use in the existing Challenger 2 fleet. The hulls will also undergo ultrasonic testing, weld repairs and repainting.<a href="#cite_note-Work_begins_to_prepare_Challenger_2_vehicles_for_upgrade_programme-97">[96]</a>

The overall scope of HAAIP includes:

<ul><li>Upgraded CV12-9A engines for Challenger 3 and CRARRV<a href="#cite_note-The_Procurement_Of_HAAIP_Main_Engine_Cooling_Fans_–_Annex_F-96">[95]</a><a href="#cite_note-des.mod.uk-98">[97]</a></li>

As of January 2022 six Challenger 2s were reported to have received the automotive upgrades prior to conversion to Challenger 3s.<a href="#cite_note-IAV_2022:_Challenger_3_upgrade_underway-106">[105]</a>

<div class="mw-heading mw-heading3"><h3 id="CSP_/_LEP_/_Challenger_3">CSP / LEP / Challenger 3</h3></div>

In 2005, the MoD recognised a need for a Capability Sustainment Programme (CSP) to extend the service life of the Challenger 2 into the mid-2030s and upgrade its mobility, lethality and survivability.<a href="#cite_note-DIS2005-107">[106]</a> The CSP was planned to be complete by 2020 and was to combine all the upgrades from CLIP, including the fitting of a 120 mm smoothbore gun.<a href="#cite_note-KRHRJ-108">[107]</a><a href="#cite_note-CSDP-109">[108]</a>

By 2014, the CSP programme had been replaced by the Life Extension Programme (LEP) which shared a similar scope of replacing obsolete components and extending the tank's service life from 2025 to 2035, however the 120 mm smoothbore gun had seemingly been abandoned.<a href="#cite_note-2014LEP-110">[109]</a><a href="#cite_note-111">[110]</a><a href="#cite_note-112">[111]</a>

In 2015, the British Army provided an insight into the scope of the LEP, dividing it into four key areas, namely:<a href="#cite_note-113">[112]</a>

<ul><li>Surveillance and target acquisition: Upgrades to the commander's primary sight and gunner's primary sight, as well as the replacement of the thermal observation and gunnery sights (TOGS) with third-generation thermal imaging.</li>

<li>Weapon control system: Upgrades to the fire control computer, fire control panel and gun processing unit.</li>

<li>Mobility: Upgrades including third-generation hydrogas suspension, improved air filtration, CV-12 common rail fuel injection, transmission and cooling.</li>

<li>Electronic architecture: Upgrades to the gunner's control handles, video distribution architecture, generic vehicle architecture compliant interfaces, increased onboard processing and improved human machine interface.</li></ul>

The MoD also began assessing <a href="Active_protection_system" title="Active protection system">active protection systems</a> (APS) on the Challenger 2, including <a href="MUSS_(countermeasure)" title="MUSS (countermeasure)">MUSS</a> and Rheinmetall's ROSY Rapid Obscurant System.<a href="#cite_note-114">[113]</a><a href="#cite_note-115">[114]</a><a href="#cite_note-116">[115]</a>

In August 2016, the MoD awarded assessment phase contracts to several companies for the Life Extension Programme. These included Team Challenger 2 (a consortium led by BAE Systems and including <a href="General_Dynamics_UK" title="General Dynamics UK">General Dynamics UK</a>),<a href="#cite_note-TeamCR2-117">[116]</a> <a href="CMI_Defence" class="mw-redirect" title="CMI Defence">CMI Defence</a> and <a href="Ricardo_plc" class="mw-redirect" title="Ricardo plc">Ricardo plc</a>, <a href="Rheinmetall" title="Rheinmetall">Rheinmetall</a> and <a href="Lockheed_Martin_UK" title="Lockheed Martin UK">Lockheed Martin UK</a>.<a href="#cite_note-assessmentphase-118">[117]</a><a href="#cite_note-Final_bids_in_for_Challenger_2_LEP-119">[118]</a> In November, the MoD shortlisted two teams led by BAE Systems and Rheinmetall to compete for the LEP which was then estimated to be worth £650 million ($802 million).<a href="#cite_note-Field_Narrows_for_UK_Battle_Tank_Modernization-120">[119]</a><a href="#cite_note-Challenger_2_LEP_contracts_due_in_December-121">[120]</a><a href="#cite_note-122">[121]</a>

In October 2018, BAE Systems unveiled its proposed Challenger 2 LEP technology demonstrator, the "Black Night".<a href="#cite_note-bk1-123">[122]</a> The new improvements included a <a href="Safran" title="Safran">Safran</a> PASEO commander's sight, <a href="Leonardo_S.p.A." class="mw-redirect" title="Leonardo S.p.A.">Leonardo</a> thermal imager for the gunner and Leonardo DNVS 4 night sight. The turret also received modifications to improve the speed of traverse and to provide greater space as well as regenerative braking to generate and store power. Other enhancements included a laser warning system and an active protection system.<a href="#cite_note-bk1-123">[122]</a><a href="#cite_note-124">[123]</a> Months later, in January 2019, Rheinmetall unveiled its proposal which included the development of a completely new turret with fully digital electronic architecture, day and night sights for the commander and gunner, and a Rheinmetall L55 120 mm smoothbore gun. Whilst a more substantial upgrade than Black Night, the turret was developed on Rheinmetall's initiative and was not funded by the UK MoD, nor was it part of the MoD's LEP requirements.<a href="#cite_note-Rheinmetall,_BAE_Systems_launch_joint_venture_for_military_vehicles.-125">[124]</a><a href="#cite_note-BAE_Systems_sells_control_of_vehicles_arm_to_Rheinmetall.-126">[125]</a><a href="#cite_note-IAV_2019:_Rheinmetall_unveils_proposal_for_Challenger_2_LEP.-127">[126]</a>

In June 2019, BAE Systems and Rheinmetall formed a joint venture company, based in the UK, named <a href="Rheinmetall_BAE_Systems_Land" title="Rheinmetall BAE Systems Land">Rheinmetall BAE Systems Land</a> (RBSL).<a href="#cite_note-RBSL_Home-128">[127]</a> Despite the merger, the company was still expected to present two separate proposals for the LEP contract,<a href="#cite_note-129">[128]</a> however, at <a href="DSEI" title="DSEI">DSEI</a> 2019, RBSL instead opted to only showcase the Rheinmetall proposal.<a href="#cite_note-130">[129]</a>

In October 2020, the MoD argued against buying a new main battle tank from overseas instead of pursuing the Challenger 2 LEP, stating that an upgraded Challenger 2 would be "comparable – and in certain areas superior" to a Leopard 2 or Abrams.<a href="#cite_note-131">[130]</a>

On 22 March 2021, the MoD published its long-awaited <a href="Command_paper" title="Command paper">command paper</a>, <a href="Defence_in_a_Competitive_Age" title="Defence in a Competitive Age">Defence in a Competitive Age</a>, which confirmed the British Army's plans to upgrade 148 Challenger 2 tanks and designate them <a href="Challenger_3" title="Challenger 3">Challenger 3</a>.<a href="#cite_note-DIACAb-132">[131]</a><a href="#cite_note-FSTBA-133">[132]</a> The MoD confirmed the contract with RBSL had been signed, valued at £800 million (US$1 billion), on 7 May 2021. Rheinmetall's more extensive upgrade proposal, including the new 120 mm smoothbore gun, had been accepted. The <a href="Initial_operating_capability" title="Initial operating capability">initial operating capability</a> for the upgraded tanks is expected by 2027, with full operation capability expected to be declared by 2030.<a href="#cite_note-dnci-35">[34]</a>

<div class="mw-heading mw-heading3"><h3 id="Other_in-service_upgrades">Other in-service upgrades</h3></div>

On 15 December 2017, BAE Systems was awarded a contract to maintain the Challenger 2's thermal imaging system as part of a £15.4 million interim solution separate to the LEP.<a href="#cite_note-134">[133]</a> In October 2019, it was announced that <a href="Thales_Group" title="Thales Group">Thales</a> would be supplying their Catherine Megapixel (MP) thermal imaging camera.<a href="#cite_note-135">[134]</a>

In August 2023, photos appeared of Challenger 2s in Ukrainian service featuring <a href="Slat_armor#Top-mounting" title="Slat armor">top-mounted slat armor</a>, similar to those found on Russian vehicles used in the conflict, primarily to protect from UAV attacks. The tank was also equipped with slat armor covering the hull flanks and lower frontal hull plate.<a href="#cite_note-telegraph-20230816-136">[135]</a>

On 21 January 2025, during DefenceIQ's International Armoured Vehicles exhibition and conference, the British Defense Ministry announced that it was trialing Challenger 2 tanks equipped with <a href="Anti-drone_cage" class="mw-redirect" title="Anti-drone cage">anti-drone cages</a>.<a href="#cite_note-137">[136]</a><a href="#cite_note-138">[137]</a>

<div class="mw-heading mw-heading3"><h3 id="Challenger_2_Driver_Training_Tank">Challenger 2 Driver Training Tank</h3></div>

The Challenger 2 Driver Training Tank (DTT) is based on the Challenger 2 hull. The turret has been replaced with a fixed weighted superstructure to accommodate an instructor and up to 4 trainees. The design is similar to the Challenger 1 derived Challenger Training Tank (CTT). Weighting the superstructure replicates the weight (and therefore also the driving characteristics) of the standard tank in operational service. 22 DTTs are in British service, with 2 in service with Oman.

<div class="mw-heading mw-heading3"><h3 id="Titan">Titan</h3></div>

The Titan <a href="Armoured_bridge_layer" class="mw-redirect" title="Armoured bridge layer">armoured bridge layer</a> is based on aspects of the Challenger 2 running gear and replaced the Chieftain Armoured Vehicle Launched Bridge (ChAVLB). The Titan came into service in 2006 with the Royal Engineers, with 33 in service. Titan can carry a single 26-metre-long bridge or two 12-metre-long bridges. It can also be fitted with a bulldozer blade.

Entering service in 2007, 33 were produced.

<div class="mw-heading mw-heading3"><h3 id="Challenger_2E">Challenger 2E</h3></div>

The Challenger 2E is an export version of the tank. It has a new integrated weapon control and battlefield management system, which includes a gyrostabilised panoramic SAGEM MVS 580-day/thermal sight for the commander and SAGEM SAVAN 15 gyrostabilised day/thermal sight for the gunner, both with eye-safe laser rangefinder. This allows hunter/killer operations with a common engagement sequence. An optional servo-controlled overhead weapons platform can be slaved to the commander's sight to allow operation independent from the turret.

The power pack has been replaced by a new 1,500 hp (1,100 kW) <a href="EuroPowerPack" title="EuroPowerPack">EuroPowerPack</a> with a transversely mounted <a href="MTU_Friedrichshafen" title="MTU Friedrichshafen">MTU</a> MT883 diesel engine coupled to <a href="Renk" title="Renk">Renk</a> HSWL 295TM automatic transmission. The increase in both vehicle performance and durability is significant. The smaller volume but more powerful EuroPowerPack additionally incorporates as standard a cooling system and air intake filtration system proved in desert use.

The free space in the hull is available for ammunition stowage or for fuel, increasing the vehicle's range to 550 km (340 mi). This power pack was previously installed on the French Leclerc tanks delivered to the UAE as well as the recovery tank version of the Leclerc in service with the French Army. Further developed versions of the EuroPowerPack have more recently been installed in the latest serial produced Korean <a href="K2_Black_Panther" title="K2 Black Panther">K2 Black Panther</a> tank.

BAES announced in 2005 that development and export marketing of 2E would stop. This has been linked by the media to the failure of the 2E to be selected for the <a href="Hellenic_Army" title="Hellenic Army">Hellenic Army</a> in 2002, a competition won by the <a href="Leopard_2" title="Leopard 2">Leopard 2</a>.<a href="#cite_note-139">[138]</a>

The tank was firing 120 mm practice shells with a standard propellant charge. The explosion critically injured the four-man crew, with two later dying of their wounds in hospital. The incident resulted in all British Army tank firing exercises being suspended for 48 hours while the cause of the explosion was investigated.<a href="#cite_note-153">[152]</a> It was later determined that a bolt vent axial (BVA) seal assembly had been removed during an earlier exercise and had not been replaced at the time of the incident, allowing explosive gases to enter the turret space; the lack of a written process for removal and replacement of the seal assembly meant that the crew at the time of the incident were unaware of its absence, and it was also noted that inadequate consideration had been given during the production of the L30 gun as to whether it could be fired without the seal assembly.
