I bought this document from the national archives back in 2019, it has been fully declassified and has been released to the public so it is no longer classified are restricted !!

Challenger 1 very early production had
275mm KE hull

After it became
300mm KE hull

The turret protection is 480-500mm KE from the front (depending on the primary source)

Me and many others tryed to do that back in the day but gaijin and the mods we’re so stubborn and straight up refused to buff challenger 1 armour are even to do anything to get Challenger 1 armor improved !!

At minimum challenger 1 ufp should be around 325mm against kinetic ammunition. Because going by current information the challenger 1 MK1 would have around 275mm on its ufp but the MK2 its ufp had an additional 50mm RHA plate had on to it which would increase its minimum protection against kinetic to 325mm. Now against chemical challenger 1 turret would have to have around 900/1000mm of protection against chemical ammunition and on the hull your looking at minimum 700mm against chemical ammunition !!

Yeah no, we know CR1 in service was 300mm KE, that additional plate appears only on old prototypes, Shir 2’s and the like.

Hmmm does at normal mean 60degree or 0degree

That document is from the Future Main Battle Tank (MBT 80) and I have that exact document and it’s from 1982 to 1983. And in that document they used a Challenger MK1 as an example tank to show its current protection values at the time to what they would like to improve it to in the 1987 PIP.

Means head on.

I haven’t seen the full thing, (especially if there is a turret diagram), but I haven’t seen any evidence suggesting the protection is better than stated here.

Thought so, shame we never got the PIP hull 550 ke and 900 ce would of been juicy. What’s a real shame is us never getting the full MBT 80 design.

I know what PIP is dw

I’m just trying to work out what spec that Challenger is in the doc, and if any turret data is given in that doc.
