Storage at the back of a Challenger 2 turret. Swings open.



Model but you get the idea.

@Laviduce I stumbled upon these. Don't know if they're any help:

£1.5bn is missing from the scheduled AFV budget according to reports and a Journalist has confirmed this with the MoD. However the MoD are quoted as saying that it isn't cut but "re-prioritised".
WCSP is speculated at £1.4-1.6bn and the final decision date should be this year. Hence why many think that WCSP has finally been cut.

The other possibility is L-ATV for MRV-P (Multi-Role Vehicle - Protected) Group 1 has been rejected by the Treasury.
L-ATV was selected by the Army without a competition on the belief that its $250,000 base price and massive US purchase meant that even with required modifications it would still be cheaper to buy and run than any other competitor.
However after some testing its rumoured to be too cramped for needed equipment. The modifications to make it UK road legal (right-hand drive) and desired protection levels have dramatically risen the average price to buy and run. Nearly all the work would be done in the US leaving little for UK industry.
Previously the Treasury wouldn't fund Piranha V for FRES UV in 2008 because for such a large deal the MoD hadn't negotiated export or IP rights. So the Army went to GD and demanded exclusive rights to Piranha V. Got told no and collapsed the deal.

Medusa:
It's a research initiative to find out the feasibility and effectiveness of a soft-kill system based on MUSS by Hensoldt. Rheinmetall's ROSY was also being looked at.

The companion programme is Icarus, which is focusing on a "sovereign" hard-kill system by Leonardo UK.

Perkins working on upgrading CV12 with common rail and new electronics rated at 1500hp.
Answer seems to imply this is for Challenger 2, which would make sense as BAE has a contract to explore powerpack upgrades.
We know that there was interest from Turkey for Altay and Nimda for India's FRCV is offering something that looks similar to their Czech T-72 upgrade (CV12@1000hp + Allsion XTG 411-6-N).

In negations with collaborators for a hybrid powerpack. 
BAE and Qinetiq?
https://www.qinetiq.com/news/2017/05/qinetiq-and-bae-systems-partner-to-exploit-electric-drive-technology-worldwide
Qinetiq used Challenger 2 as an example for their E-X-Drive at IAV 2019:


There was a report (https://www.janes.com/article/85620/uk-mod-kicks-off-electric-vehicle-drive-study) that the British Army wants to hybridise their fleet of vehicles.
All of the above points to a 1500hp modernised CV12 + E-X-Drive powerpack for Challenger 2 as a real possibility. MTU has recently gained a foothold in the UK market with Ajax & Boxer and would most likely offer to upgrade CR2, this seems to be Perkins/Caterpillar's response.
