[HT] Explosive Reactive Armor: Part II

General Lee · 05-20-2013, 09:25 PM

Hello, folks.

Some time ago, I started a thread about Explosive Reactive Armor (right, right I misspelled it, here).

Despite the effort, I still have some doubts about how ERA works in game.

Recently, I come to play with armored vehicles again and the question about ERA armor came up one more time.

But, this time I do some research and give a new thought.

For starts, I found (ok, one I already see here in this forum quoted by Douglas Cole) two sites of huge help about this topic.

This have RHA estimatives for modern tanks: http://collinsj.tripod.com/protect.htm

And this, explain how a reactive armor works, and give an estimate for RHA equivalent armor for Kontakt-5 ERA that is both effective against chemical rounds (HEAT, HEADP) and Kinectic rounds (APFSDS). http://www.russianarmor.info/

On this last site, I found that Kontakt-5 have RHAe of 250mm (DR 700) vs Kinectic and 600mm (DR 1680) vs Chemical.

Now, the problem: Only MS-HEAT could inflict damage to vehicles when these have ERA armor or not? For example, a Leopard 1A5 ( Turret DR 1260 [against HEAT/ RHAe 450mmm) with ERA ( plus DR 700/ 250mm [based on ERA used in M60 A1] would give a total DR 1960. So a HEAT missile that does more than 560d [7dx8(10)] with one warhead would still penetrate?
