Challenger 2 MBT - Technical data and Discussion (Part 1)

Falcon is going to speed run to 12.0

I do :)

Then I’ll probably see if I can make a quick trip sometime this week or next week. I love going there and now I can at least help a little. Although I’m not sure how I’m going to go about asking whether or not the backing plate is made of steal or aluminium lol.

Easy! If it’s on display, no need. Bring a magnet and quickly try to magnetise to the Bulldog Mk.3’s backing plate. If it doesn’t stick, either: The paint is too thick or it’s made of a non magnetic material.

Aluminium is non-magnetic
Steel is.

This will give us decent results o7

Np. I’ll look shady but who cares. I’ll use a neodymium magnet just to make sure it really is steal.

I mean, that is yet simple yet flawless

Checkmate, Snail, can’t disprove magnetism lol.

I can see it now, ‘this youtube video of some random british person sticking a magnet to a bulldog is clearly edited, look they have a blurred face showing it is!’

Anybody want to squad up for some Chally games?

If they fix the challengers I’ll buy every premium on the storepage.

Hopefully someone from the sales department is watching this thread haha

If they fix it, I’ll 100% buy the OES (for 50% off)

Posting this here so it’s in the right thread:
ASPRO-HMT should provide 240MM of KE resistance at 67 degrees and 120MM of KE resistance at 0 degrees and here’s why:

A) We know from looking at the testing ranges, wording and methodology documentation for STANAG 4569 that panels are tested individually. So a single ASPRO-HMT block can stop 25mm at 67 degrees.
B) To stop 25mm at 67 degrees, a single block must provide 48mm of KE to stop it before it exits out the other side
C) We know from “Images of War”, ASPRO-HMT’s insides are reactive (explosive) tiles and Passive (Chobham type) composite tiles layed out in series.
D) Because at 67 degrees, the round is not encountering 100% of the width of ASPRO-HMT, but rather just about 20% and still managed to stop 25MM, we can use these values to determine the KE resistances for - Multiple blocks in a row where the round encounters 100% of the passive tiles over 3 blocks at 67 degrees, and the KE resistance of 1 block at 0 degrees.

In short, if 20% of the width of a single block is 48mm KE, 100% is equal to 240mm, if at 67 degrees, the round continues encountering ASPRO-HMT blocks at that angle.
At 67 degrees however, the passive tiles provide more KE because they are angled. To correct for this and find 0 degrees KE, we can divide by two, assuming that angling provides roughly twice the amount of KE as flat penetration, giving us 120mm of KE at 0 degrees.

@Gunjob Feel free to take a squiz, as I think this is pretty clean maths and makes sense given the sources claims. I’ve included all this info in my bug report here: Community Bug Reporting System

In any case, 30 KE is simply too low

Sorry Disregarded, Cannot be better than Kontakt or Relikt.

Then we’re in luck! Relict gives 10mm more :P (well…about 130mm more, given this is flat pen and ours is 120mm)

lol :p

and it is only era and no where near as thick

The big thing here, is Relict is very compact and uses explosives to shatter incoming rounds.
ASPRO-HMT is more like spaced composite armor, but replaces the airgaps with explosive tiles that can only be set off from HEAT rounds. There’s no dart shattering going on in ASPRO-HMT, instead, it’s a full hybrid passive armor suite when hit by KE rounds.
It makes sense that something almost 4-5 times thicker than Relict is comparable.

Where Relict explodes and is a “one and done” ERA
ASPRO-HMT is a hybrid armor suite capable of taking multiple shots without detonating.
The drawback of ASPRO-HMT being, it’s FAR thicker and FAR heavier, but achieves multi-shot capability.
The drawback of Relict is it’s a one and done solution, but far more slimmer and light weight.

It’s also because of this layering of Reactive and Passive tiles, that ASPRO-HMT can survive tandem warhead impacts.
The frontal breaching charge of a tandem warhead is relatively weak, so it won’t pen through the entire block. The follow up warhead is far more powerful, but encounters the unexploded remaining tiles the breaching warhead failed to contact.

The entire tandem attack is defeated owing to Rafaels ERA tiles ONLY exploding when the shaped charge projectile hits the tiles. If it doesn’t touch a tile, it wont detonate.

So you’d end up with the breaching charge blowing through 30-40% of the tiles it impacts before stopping, leaving the other 60-70% of unexploded tiles to catch the warhead.

I cant wait for them to completely ignore all that info and say ur wrong ;D
