=== Challenger 2 Driver Training Tank ===

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.

=== Titan ===

The Titan [[Armoured vehicle-launched bridge|armoured bridge layer]] 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.

=== Trojan ===

The Trojan [[Armoured Vehicle Royal Engineers]] is a [[combat engineering vehicle]] designed as a replacement for the ''Chieftain AVRE'' (ChAVRE). It uses the Challenger 2 chassis, and carries an articulated excavator arm, a dozer blade, and attachment rails for [[fascine]]s. Entering service in 2007, 33 were produced.

=== Challenger 2E ===
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The power pack has been replaced by a new {{convert|1500|hp|kW|abbr=on}} [[EuroPowerPack]] with a transversely mounted [[MTU Friedrichshafen|MTU]] MT883 diesel engine coupled to [[Renk]] HSWL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 {{convert|550|km|abbr=on}}. 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 [[K2 Black Panther]] 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 [[Hellenic Army]] in 2002, a competition won by the [[Leopard 2]].<ref>{{cite web |url=http://www.janes.com/defence/land_forces/news/jdi/jdi050518_1_n.shtml |title=Challenger nears end of the line |publisher=Jane's Land Forces News |archive-url=https://web.archive.org/web/20070214142612/http://www.janes.com/defence/land_forces/news/jdi/jdi050518_1_n.shtml |archive-date=14 February 2007}}</ref>

The [[Challenger Armoured Repair and Recovery Vehicle]] (CRARRV) is an [[armoured recovery vehicle]] based on the Challenger 1 hull, designed to repair and recover damaged tanks on the battlefield. Ordered in 1985, and delivered between 1988 and 1993, the CRARRV has subsequently been updated to use a Challenger 2 powertrain consisting of a CV12-5C/6C engine<ref name="Challenger Tanks: Engines (Qs.1)">{{Cite web |url=https://www.theyworkforyou.com/wrans/?id=2022-04-06.HL7761.h&s=speaker%3A25229#gHL7761.q0 |title=Challenger Tanks: Engines (Qs.1) |website=TheyWorkForYou |publisher=UK Parliament |date=22 April 2022 |access-date=24 April 2022}}</ref> with TN54E transmission. The British Army ordered 80 vehicles. Four CRARRVs were purchased by Oman to complement their acquisition of Challenger 2 tanks.

CRARRVs were first deployed in action in the lead up to the [[Gulf War|First Gulf War]], [[Operation Granby]] in 1991. They were subsequently deployed during the [[2003 invasion of Iraq]], [[Operation Telic]] in 2003, alongside standard Challenger 2 MBTs.[[File:Challenger 2 UA.jpg|thumb|Ukrainian Challenger 2 in November 2024]]
