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

L23+L18A1
The L23A1 piercing projectile, L29A1 training projectile and L18A1 propellant on display at the military training area in Salisbury, UK, for the 120mm L30A1 rifle-bore gun of the Challenger 2 tank. This configuration demonstrates the feasibility of mixing L23A1 and L18A1 propellant and has been exported to Oman. ​​​

L23 can be fired with the L12 charge, however we don’t know the velocity for that.

I think that if the change of L23A1 using L18A1 propellant would ever happen we could find Oman test / archive telling us what we need and even if this is not the case as they have already done it for others nation and based on the evidence that an other propellant may be used they can actually speculate the performance / buff based on the L26 enhanced performance between L11A5 and L30A1 gun.

If I use a really bad method to speculate based on L26 :
L26 on L11A5 with an angle of 0° and 500m = 464
L26 on L30A1 with an angle of 0° and 500m = 487

so there is a 23mm difference.
At 30° the enhancement is set at 19mm .

Based on that and as L23A1 is lighter than L26 let’s say it add only 20mm at 0° and 16mm at 30°
it would mean that stock ammunition have a penetration of :

407mm at 500m / 0°
and
343mm at 500m / 30°

if you compare it with the OFL 120 G1
417mm at 500m / 0°
and
352mm at 500m / 30°

And we’re still pretty close to DM23 which is more a 10.3 munition anyway.

( Understand that it’s just dumb speculation with 0 evidence and totally speculated numbers don’t throw rocks at me I do think that put it like that with an “example” of how it could improve the L23A1 is interesting to show that it’s not just an unnecessary buff ).

Can’t use L26 since that data is also speculatory, however we know its actual MV is ≈1600m/s for L30.

got myself another book (well 10 books but this is the only one challenger related) XD

3.99??? That thing costs 25 euro in my country before currency conversion (with that 5x more without delivery, with delivery nearly 7x)

Played 2 matches in the CR2 today.

First match we got steamrolled.
Second match, we got steamrolled.

If the devs dont fix the CR2s, they need to go down in BR

CR2 to 10.7
2F, TES & OES to 11.0
2E & BN to 11.3

And a side note to that, the ADATS M113 is 11.0 at best.

Living in the UK is also a nightmare for playing this game.
We’re literally in the middle timezone to two of the largest playerbases.

Ok, im jumping on and we are doing it. WE WIN THIS!

https://www.naval-military-press.com/
found a british book shop that has major discounts, shipping for me is still about 30€, but since i bought 10 books its worth it

my games haven’t been going great.
IMO the ADATS is brilliant even at this br

Dont get me wrong, the ADATS is good, but CAS users are evolving. GBUs can be dropped beyond the range of the ADATS missile.

Its not as good against tanks anymore due to the improved CE Protection tanks have at 11.7.

Maybe 11.3 would suit it better.

Yeah, only the pantsir can really do effective air defence against jets now, great to see the best AA going to the country that uses the most heli’s…

We should get a vehicle that can tow around a rapier.

Or the tracked rapier

Tracked rapier i believe has been ‘passed to devs’ for some time now.
Even so, the rapier has a shorter range than the ADATS.
6.6ish Miles for the ADATS and 5.1ish Miles for the Rapier.

Would be good around the 10.7 mark.

Dont hold out hope thought, the Stormer AD was passed to devs 5 years ago.

Sky Sabre is probably the only thing we can get that is as effective as the Pantsir.

thought the radar had a range of 15km?

Radar range yes, effective missile range, not so much

then we require the sky sabre system, just need 3 players to use it :)


thats how little air defence trucks are made

Nah, missile truck can fire by itself, just without search radar

Isnt the radar on the missile carrier itself, a short range search & track?

The Giraffe radar is for long range target detection.

The search got ditched in place of DL mast early in developement, tracker is still there
IR Tracker extended, it is on the smaller mast


Another, now from the polish NAREW

Here you can see IRT mast folded
