Challenger 3 (CR3) is a British fourth-generation main battle tank in development for the British Army. It will be produced by the conversion of existing Challenger 2 tanks by the British/German Rheinmetall BAE Systems Land joint venture.

Development overview

Improvements to Challenger 2 began in 2005 as the Capability And Sustainment Programme (CSP) to keep the Challenger 2 competitive until the 2030s. Lack of funding [14] meant that it was not until 2014 that the programme was formally reorganised into the "Challenger 2 Life Extension Programme" (LEP). In response to the LEP programme, two prototypes were submitted for evaluation; one from BAE Systems in 2018 [15] and the other from Rheinmetall in 2019. [16] Later that year BAE and Rheinmetall merged their British operations into Rheinmetall BAE Systems Land (RBSL), effectively leaving Rheinmetall's proposal the only option available without replacing the Challenger 2 fleet with foreign models. [17]

The Challenger 3 has an all-new turret with an improved hull. The most significant change from Challenger 2 to Challenger 3 is the replacement of the Challenger's main armament from a 120 mm L30A1 rifled main gun to the 120 mm L55A1 [18] smoothbore gun (which itself is an upgraded version of the L55 fitted to the Leopard 2A6/A7 family of main battle tanks) giving commonality with other NATO members. Ammunition is to be developed in conjunction with Rheinmetall AG, with a new kinetic energy round being developed for Challenger 3 and Leopard 2. [19]

The Challenger 3 core weight is expected to be about 66 tonnes (65 long tons; 73 short tons), but the weight of the deployable configuration is withheld for security reasons. [20]

Costs and service dates

The initial entry into service of the Challenger 3 has been brought forward to 2025, not 2027 as originally planned. The first units are to be delivered to the British Army in 2025. A total of 148 tanks are to be produced, with core development costs estimated at 906.9 million British pounds sterling (1.17 billion US dollars). [21] By the spring of 2024, eight pre-production tanks had been delivered and trials had commenced in Germany. In January 2024, another contract was awarded to RBSL to provide a new modular armour system for Challenger 3. [22]

In 2021 whole life costs were estimated to be £1.3 billion, [23] but by 2024 the MOD internal budgeted estimate of whole life costs had increased to £1,987 million which now includes the modular armour system and active protection system. [24]

History

The Challenger 3 will be the fourth tank of this name, the first being the World War II Cruiser Mk VIII Challenger, which was developed from the Cromwell tank chassis and armed with a Ordnance QF 17-pounder. [25] The second was the Gulf War-era Challenger 1, which was the British army's main battle tank (MBT) from the early 1980s to the mid-1990s, when it was succeeded by the Challenger 2 which saw action during the Iraq War in 2003. [26]

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. [27] The CSP was planned to be complete by 2020 and was to combine all the upgrades from CLIP (Challenger Lethality Improvement Programme), including the fitting of a 120 mm smoothbore gun. [28] [29] By 2014, the CSP 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. [30] [31] [32] The development project, named "Armour MBT", was formally started in December 2014. [24]

In 2015, the British Army provided an insight into the scope of the LEP, dividing it into four key areas: [33]

The MOD also began assessing active protection systems (APS) on the Challenger 2, including MUSS and Rheinmetall's ROSY Rapid Obscurant System. [34] [35] [36]

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 General Dynamics UK), [37] CMI Defence and Ricardo plc, Rheinmetall and Lockheed Martin UK. [38] [39] 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 (US$802 million). [40] [41] [42]

In October 2018, BAE Systems unveiled its proposed Challenger 2 LEP technology demonstrator, the "Black Night". [43] The new improvements included a Safran PASEO commander’s sight, Leonardo thermal imager for the gunner and Leonardo DNVS 4 night sight.[ citation needed ] The turret also received modifications to improve the speed of traverse and to provide greater space, and regenerative braking to store energy. Other enhancements included a laser warning system and an active protection system. [43]

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. [16]

In June 2019, BAE Systems and Rheinmetall formed a joint venture company, based in the UK, named Rheinmetall BAE Systems Land (RBSL). [44] Despite the merger, the company was still expected to present two separate proposals for the LEP contract.[ citation needed ] [45] At DSEI 2019, RBSL first showed the 120mm proposal. [46]

In July 2020, Rheinmetall Defence showed a testbed vehicle on the Challenger 2 chassis, with a brand new turret, autoloading system and a powerful 130 mm smoothbore gun, the Rheinmetall Rh-130 L/51. [47] The 130 mm L/51 is 500 kilograms heavier than existing 120 mm L/44 or L/55 cannons and would require a larger turret to use on the Challenger 3. [48]

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 Leopard 2 or M1 Abrams". [49]

The management of the C2 LEP was scathingly criticized by the Defence Select Committee on 15 March 2021. [50] They said in a report entitled "Obsolescent and outgunned: the British Army's armoured vehicle capability", [51] that "Despite having spent around 50% of the allocated budget (£800 million), the programme has yet to place a manufacturing contract. The programme has a current in-service date of 2024 (originally planned for 2017) and is some £227 million over budget. After a decade of effort, this abject failure to deliver against both cost, (with an overrun now totalling over a quarter of a billion pounds of public money) and timescale (ISD seven years late) is clearly totally unacceptable. Nevertheless, it is symptomatic of the extremely weak management of Army equipment programmes, by both Defence Equipment and Support and the Army Board itself, in recent years." [52]

On 22 March 2021 Defence Minister Ben Wallace presented the command paper Defence in a Competitive Age to Parliament, which confirmed the British Army's plans to upgrade 148 Challenger 2 tanks for "around £1.3bn" and designate them Challenger 3. [53] [54] The MOD confirmed the contract with RBSL had been signed, valued at £800 million (USD$1 billion), on 7 May 2021. Rheinmetall's more extensive upgrade proposal, including the new 120 mm smoothbore gun, had been accepted. The initial operating capability for the upgraded tanks is expected by 2027, with full operation capability expected to be declared by 2030. [55]

It was announced on 23 January 2024 that the first pre-production Challenger 3 had been delivered, [56] with trials commencing in Germany in February [57] and the first live-firing of the main armament in April. [58] On 18 April 2024, the Defence Secretary, Grant Shapps, attended the rollout of the last of eight pre-production models at the RBSL factory in Telford. [59] A Ministry of Defence statement claimed that nearly 300 jobs would be created at the RBSL plant, with a further 450 jobs around the UK in a supply chain of companies based in the West Midlands, Glasgow, Newcastle upon Tyne and the Isle of Wight. [60]

A drawback of the adoption of the L55A1 smoothbore gun is that it is incompatible with the depleted uranium ammunition used by Challenger 2, and that the NATO standard tungsten ammunition is less effective. On 27 April 2024, the Ministry of Defence announced that a statement of intent had been signed with Germany for the development of an Enhanced Kinetic Energy (EKE) armour-piercing round for both Challenger 3 and Leopard 2 tanks.

Compared to financial year 22/23-Q4, the project's departmental-agree Whole Life Cost at 23/24-Q4 increased from 1435m to 1987m. This is primarily due to the following factors. At Q4 22/23 the Baseline Whole Life cost was 1435m. Following completion of EPSOM (New Armour System) negotiations this decreased by 13m to 1422m. As at March 2024 the new WLC of 1985m includes the costings for the full EPSOM 148 Inert sets and Active Protection System D&M.
