Challenger 1 MBT - Technical Data and Discussions

I am not doughting that am just add more proof that the document you uploaded there is infact from the segment in the MBT 80 document that goes on about how they were planning a concept tank for 1987 and that they were comparing their concept tank to a Challenger 1 MK1 !!

What’s the proof it’s compared to the MK1?

Emm… the year challenger 1 Mk1 went into service in 1983 and MK2 s when into service in 1986 !!

Also get a picture of a challenger 1 MK1 and a Challenger 1 MK2 are Mk3 and look at the hull it gets significantly thicker on the mk2s compared to the mk1s !!

There doesn’t seem to be any evidence for the armour changing between variants.

Note, in 1989(I’m presuming), Challenger 1’s hull was described as needing improvement. And a turret armour improvement was planned in future batches, and potentially for refit.

It could be possible that they could have retrofit mk2s down the lines and the mk3s could have been given upgraded armour ??

i doubt that, by that time Challenger replacement was in the works.

Regarding the in progress changes seen on the dev for the Challenger 1. The filling being missing is because its damage model is being updated and will be finished in time for the release of the major.


Am trying to get a hold of this document but it’s a bit out of my budget.

I should do a trip down to Kew at some point and get copies, assuming they’re not still classified in any way of course.

Just have to explain to the wife while I need to go to London for a tank game 🀣


πŸ˜‚πŸ˜‚πŸ˜‚ lol, and most if not all of the documents should be declassified and open to the public by now !!

seem like mk3 change too

We got a problem guys. Gaijin removed the composite from the UFP shoulders. Effectively removing ALL of its hull arc protection. Does anyone have any documents proving they had composite in them. Im 100% sure they are NOT hollow on Mk2s and Mk3s

So the source that was submitted is an assumption that a self contained composite package couldnt have been in the partitioned shoulder armor because there are no NERA mounting points like the huge chobam pieces for the frontal glacis and turret. Its a picture of a challenger hull in production.

yeah, also the fact they were sealed before the special armour was added.

Where is this fact though?

My problem with that. Is Junkyard Challenger. Chobham is Classified still. And Junkyard challenger was completely stripped. If those are truly empty, then why does junkyard challenger have the covers removed, and the should armor emptied. If there wasnt anything in them, then they shouldnt have had the covers removed. But they are. Like the production photos are an assumption because a lack of conventional mounting points.

My proof of this is the turret sides clearly visible here. Non conventional mounting points compared to the turret and hull front. But composite was mounted to the turret sides
