First things first, L15A5, as a IMPROVED version of L15A3 we have in game, Should have around 325-350mm of Penetration, NOT the same 298mm of penetration as the Earlier L15A3 round.
To add to this,(and i could be wrong with this)
I BELIEVE That the FV4030 had the Perkins CV12 it was installed with, cranked up to the FULL 1500hp the engine was capable of, and had been thoroughly tested During the MBT-80 Program. Not the detuned 1200hp that the Challenger 1 actually entered production with. as the FV4030, despite being a Challenger 1 Prototype, was still descended from the MBT-80, and the Extra horsepower was still thought as needed.
My biggest concern for the FV4030/3 is its BR. 9.7 just seems a bit wierd to me as we have basically no 9.7 line-up. Should just get dropped down to 9.3 with a slight fire rate nerf or given L23A1 and moved to 10.0.
FV 4030/3 wasn’t a descendent of the MBT-80; it was a completely separate project for Iran, and a descendent of the Chieftain. It retained essentially the same 1,200 hp power pack as the FV 4030/2 (Shir 1 / Khalid).
Once the Iranian order was cancelled the MOD decided it would be quicker / cheaper to make some tweaks to the FV 4030/3 rather than continue with MBT-80 so they went down that route.
HEATFS only sucks when you face tanks with a mass of ERA right? Shouldnt necessarily be an issue for the BR except in uptiers where it would face the TURMS
The earliest ones will be T-64A, T-72A then T-64B they all have composite so it’s hard to do any damage to them frontally with HEAT, then Merkavas are pretty much immune to them too, and then uptier you get T-72B which is better armored than TURMS even the T-64B is more armored, at least aiming at weakspot with one of the best APDS will almost always guaranteed kill, the lower plate of T-series is incredibly weak though, you literally just punch through them with ease using those 100mm APHE that the Chinese T-54s were using lol
L15A5 has a tungsten alloy core which is far denser than the previous copper cobalt core i believe in the A3.
The L15A5 round could penetrate the frontal slope of a T64A at 2000 meters.
ive wanted this round added for the mk5 and khalid and mk10 for ages and now its literally just Copy and paste L15A3
Shir 2 being the same BR as Shir 1 would be incredibly stupid and overall worse than it seeing 10.7 as it would be a challenger 1 tier of armour facing T55 AMD variants. It would be really unfair
