UK IFV Warrior, new infomation.

[Listy]

Right We're all aware that those huge slabs of Chobahm are good at stopping RPG-7's, linked to the WR's surviabilty makes them Quite a good vehicle... HOWEVER:



A closer look:



That looks Like Extra Slat armour on over the Chobahm armour, it looks to be placed mainly to protect the area's that the Chobham doesn't cover. So maybe even bigger Anti-heat value on the sides and front of the WR in the next update?
Edit: looking closer, it seems to be on the turret as well.
Thsoe where taken with 1BW in iraq.

I've also read that the WR fleet is getting a Balistic Computer upgrade, and I'm still waiting to find out details.

EDIT: Here's hte link for the details of the Fire control upgrade:

Slat armor is really good at stoping RPG.It neeeds to be better modelled in WinSPMBT.By now, stryker could be killed with all RPGs quite easily.In real,slat armor could stop 70% of them completly( as it work to prevent them to detonate).30% hits will go through the grill with reduced penetration ability (it must burn through the grill, it will loss over 20cm in penetration, but it depends how modern the warhead is.) So such armored Warrior could be quite imune against RPG fire, as its armor could stop remaining plasma.

The Stryker featureed in the game is the basic version without addon armour. If you want to add slat version, look into the "player icon mods" thread, Stirling posted a pack including an icon for such a one.

Tsahal has been using that kind of standoff RPG armor on their APCs for years. Not to mention the chain necklace on the Merkavas; the whole concept derived from the RPG fences used in Vietnam.

So it has to be modelled in the game, on the most modern Israeli M-113 derivates. Look at their HEAT armor rating: either you will have a good starting base for SLAT, or you'll have something else to upgrade!

I guess you could also start with the dozer-blade additional armor: look at the bonus the mine tanks get on frontal HEAT armor.

Hmm, i've thought that game Stryker+ is the variant with slated armour.After all, it has some (altrough far too low) anti-HEAT armour.

Anyway, in Iraq, polish BRDM-2s and Szakals (Jackals) (wich are BRDM-2s modified for desert conditions) use "mud flaps"- like side shields:


(This is actually modified Brdm-2 Zbik-B)

Well, afaik those shields aren't as effective as true bar cage (but better than nothing, i guess). Very nice slated armor for Szakal was developed, but our decidents still havent decided to buy it ( grrr.):

(in polish, but there are some other nice pics there.)

Isn't there meant the be an intermediate aodd-on armor pack (applique armor), like the ones you find on many recent AFVs?

I don't know if this was ever fielded, and if it was, whether it was then sent to Iraq or if the deployed troops have transitionned to slat armor right away.

Applique armor would match the slight improve in HEAT armor of the Stryker+

Whoops, looks like the Australians are going for SLAT too:

This comes from a Chinese website, which says source is Jane's Defense Weekly. Apparently the Australian scurity forces in Iraq have adapted Stryker-similar slat armor on their 18 ASLAV-25s.

SLAT armor will be effective against older RPGs, but will have smaller effect on more modern warheads like RPG-7VR. So simpliest solution is +33cm HEAT armor to covered areas. SLAT armor will not provide much protection against bigger ATGM missiles(Hellfires,AT-6,9 e.t.c... have better pen than 33..) as their mass and speed could destroy grill and penetrate base armor.

Are you sure about that? ATGMs are generally somewhat slower than RPG rockets and such, and have therefore less kinetic energy to smash the grid. Anyway most HEAT warheads have quite a fragile front cover and thin detonator, and will get crushed against the bars without detonating.

And even if they do detonate, the penetrator will have to cross a great amount of air that will slow it down, cool it down slightly and presumably deflect and disperse it.

So the question is: how much does this air layer affect the penetrator? In other words, how much steel does it stand for against HEAT?
I think we can neglect the thickness of the grid itself, so the main up-armoring component will be air, in the case where the rocket detonates.

SLAT is not like a classic armor! it prevents warhead to detonate.Fuse dont hit anything, so it will not explode. Bigger ATGM like hellfire are too big. their weight is much bigger, so they demolate SLAT cage at impact and then detonate.Most of modern ATGM has tandem warhead, so if first warhead is damaged at the impact, second will penetrate thru... SLAT is perfect solution fot urban fighting, but will not help against heavy ATGM or tank HEAT round.

[JaM]

Modern warhead will not be affected. Air is not good thing at stoping jet of plasma from penetrating.WW2 HEAT were affected, but technology is far better than in WW2. If you remember, in 2004 there were a situation that wonderweapon disabled Abrams.They thought that it was EM weapon, but at the end after some tests they found that it was just tandem warhead RPG.Side skirts didnt stop penetration even of first warhead. second burned through tank and exited at the other side!
