[2.14.0.29] Puma IFV's KLARA ERA provides too little protection.

[Jεcka 4,618]

KLARA currently provides 5mm vs APFSDS and 500mm vs CE, that is wrong. 

 

As reported by:

 

Light version of CLARA ERA was able to stop RPG-7V as well as 30mm APFSDS (at least 120mm of peneration).

As reported by: https://below-the-turret-ring.blogspot.com/2016/04/

 

"It provides protection against single stage shaped charges (as used on most RPGs), EFPs and in case of the heavy version against kinetic energy penetrators up to 30 mm APFSDS."

"The company showed Ultrax based plates, capable of stopping multiple hits of armor-piercing round up to 30mm. The specific weight of such armor is 70km/m2. The CLARA non-metallic explosive reactive armor system was also unveiled by Dynamit Nobel, this product uses Ultrax base passive armor layers and cases made of copmposites, to contain the explosive elements of the ERA"

"The lightweight metal-free CLARA reactive armor module combines layers of sheet explosives and composites which effectively... the Ultrax base armor, the combined module provides protection both against RPG/ATGW attacks as well as KE threats"

 

As we can see, CLARA by itself should be protecting against 30mm APFSDS - that is validated by Puma's requirements - those being STANAG lv. 6 which requires side protection against medium calibre (30mm APFSDS and up).

"defined as the weight of the armoured panel (in grammes per square metre) divided by the protection area of the panel – varying between 70 and 270 kg per square metre. The lowest-density segments provide protection against RPGs, while the strongest variant can stop 30mm sabot rounds"

Hello, thank you for your interest in improving the game! I'd need at least one more secondary source in the form of a defence or tech magazine to process this report.

 

Cheers.
