Asked by: Lord Richards of Herstmonceux (Crossbench - Life peer)
Question to the Ministry of Defence:
To ask Her Majesty's Government what variants of CV12 power packs are fitted to (1) the Challenger 2 tank, (2) the Challenger Armoured Recovery and Repair Vehicle (CHARRV), and (3) the Trojan armoured engineer tank.
Answered by Baroness Goldie
The variants of the CV12 powerpacks fitted to the Challenger base vehicle family are:
| Powerpack |
Challenger 2 | CV12-6A |
Challenger 3 | CV12-9A |
Challenger Armoured Recovery and Repair Vehicle (CRARRV) | CV12-5C/6C |
TITAN/TROJAN | CV12-8A |
A small number of CRARRV vehicles are currently fitted with CV12-5C powerpacks that will be replaced with CV12-6C powerpacks on failure or when the vehicle is attending base workshop, whichever comes first.

Question to the Ministry of Defence:
To ask Her Majesty's Government whether the power pack fitted to the new Challenger 3 is (1) a contemporary CV12 engine similar to a 5A, or (2) a CV12 with common rail fuel injection and new engine management system, or (3) something else; and if it is something else, what is its specification.

Question to the Ministry of Defence:
To ask Her Majesty's Government what progress they have made in rationalising the variants of the CV12 power packs fitted to the various marks and variants of the Challenger 2 tank, including the armoured engineer vehicles.
Answered by Baroness Goldie
Overall powerpack commonality can be only achieved between Challenger 2, Challenger 3 and the Challenger Armoured Recovery and Repair Vehicle following the identification of a replacement refrigerant to fill the crew temperature control system to comply with the Montreal protocol. A post-design services task has been placed on contract with Rheinmetall BAE Systems Land for this work.

Question to the Ministry of Defence:
To ask Her Majesty's Government whether the Challenger 3 tank has been trialled by (1) the Armoured Trials and Development Unit at Bovington, or (2) an equivalent establishment; and if so, (a) what track mileage has been covered so far, and (b) with what type of power pack.
Answered by Baroness Goldie
The Challenger 3 programme remains in the early stages of Demonstration and Manufacture, with detailed design work ongoing prior to Critical Design Review. The assembly of initial prototypes will follow along with a detailed trials programme.
