I haven't seen pictures of the current BMD-4M being airdropped. But that news report says it's been tested by being airdropped, etc. The new parachute system is able to handle weight at least up to 19 tons. The BMD-4M is not that heavy. 14 tons according to the news report, (probably closer to 14,5 ~ tons.). So...
Those applique arrays would make a good buffer and mounting point for ERA i'd think.Quick question, as I am aware ERA could not be installed upon BMPs/BMDs easily due to the armor being too light to withstand its own detonation, with the addition of additional spaced and layered armor in the BMD-4M could we in theory expect to see something capable of withstanding even the lightest of ERA Bricks on atleast a few of these surfaces? Can someone better inform me of dynamic protection/ERA requirements?
It's just a speculation, but for a vehicle that acts as troop transportation, it's not dangerous have ERA type armor? I mean, if the BMD-4 are embarking infantry soldiers and ERA reacts to shots, I suppose that the infantry squad will sustain some injuries if ERA explode. In nowadays conflicts, normally you fight in urban environment, so it's not so unbelievable that the infantry squad will be engaged near his vehicle.
If ERA can hurt infantry standing by next to it, that means that the infantry is from the side of incoming round. Let's say there is no ERA and one RPG hits the vehicle from a side where Infantry is standing. Won't that RPG cause casualties to infantrymen? Really?
Why this isn't the issue for Bradley IFV or for Namer APC having ERA on their sides, but it always has to be an issue for Russian IFVs.
Russians offer BMP-3M version for export with ERA and Arena-E. If any buyer wants it, he can get it.
Why Russian Army doesn't use ERA on BMP-3:
- The first and main reason as always is a lack of funds after 90s.
- ERA for BMP-3 weights 4.3 tons. Obviously the vehicle looses mobility characteristics and maybe even its amphibious capabilities. But that's not a problem in areas where they are not needed... see BMD-2D armor upgrade for Afghanistan, when the vehicle became heavier and couldn't swim any more.
- BMD-4 wasn't even in service in serious numbers to consider installing ERA on it and again +4tons can deny air-drop capabilities from it. That's why I said, that it would be nice if Russians would come up with modular ERA.
Bottom line: IFVs in class of 20-30tons can hold ERA detonation without ripping their own hulls. Bradley is an example in service.
I dont know if repost.
