AMV 8X8 Armoured Modular Vehicle
Hmm, Patria seems to be increasing their advertising of the AMV 8x8 and they're really pushing the "family of vehicle" concept. Did you notice a few images of the vehicle undergoing testing by the USMC?
Question. Why is internal storage of gear by attached infantry such a big deal? If the vehicle is hit or sinks while swimming, its more stuff to try and get out of the way before you can cleanly exit and it requires the vehicle to be a bit larger than it has to be. If anything build some racks to store the rucksacks or simply provide tie down points.

My guess is storing it internally in designated places can keep the weight from affecting the vehicles center of gravity. Also if stuff is hanging off the sides it might cause drag in the water while swimming.
ReplyDeletecenter of gravity because you hang rucks off the side in combat? kinda doubt that, its done all the time. we used to tiedown rucks on top of the vehicle when swimming so i don't think that would affect drag. but i guess its irrelevant. you talk about storing everything internally and you're increasing vehicle size unnecessarily in my opinion.

DeleteI was thinking of stuff in addition to the rucks. Looking back my original comment does sound silly for rucks alone.
DeleteWhat is the vehicle deploying at the 48 second mark?
ReplyDeleteyou mean when its deploying some type of mast? i have no idea. i've seen that one for a while now and have never taken the time to run that down. if its some type of radar and electronic warfare setup it seems kinda strange. i know its not a cannon of some sort so what is it? i have absolutely no idea.
DeleteRebroadcast station? Most people don't know that radio has a limited range and you need to boost the power through relay stations to communicate long distances.
DeleteCould it be the world's tallest snorkel? Too small to be a launcher or gun. To lacking in antennas to be a com-mask.
DeleteThere might be a super small dish at the end, but I think it's just an empty com/radar-mast just for show/test.
DeleteI wonder why nobody (to the best of my knowledge) has designed slat armour in the form of storage racks. It seems like such a perfectly logical thing to do.
ReplyDeleteDefeats the purpose. Slat armour is supposed to crush the RPG head by making it slip between the bars. Putting stuff in it fills the space between, making it more likely to trigger the RPG warhead instead.
DeleteOwl, who told you the purpose of slat armor is to crush a warhead? The purpose of slat armor is to detonate the warhead prematurely, so tossing some duffle bags or rucksacks between the hull and the slat isn't a big deal.
DeleteThe firing circuit of an RPG-7 runs through the conductive inner ogive. Crushing the outer nosecone forces the outer casing into contact with the inner one, causing a short circuit. The secondary effect is to deform the conical liner that folds in to form the penetrator, instead of folding into a spear, it will end up something like a frisbee and bounce off the armour.
DeleteThe standoff detonation is an urban myth, a properly formed penetration jet is measured in meters, the 20 or so cm that slat armour may detonate a round further isn't really going to matter. And that is even assuming that the round hits the slate head on with the fuse. If it is for standoff, why not put a whole plate there instead of grills? Because the grills are the defence, not the distance. You don't want an RPG to hit a slate head on, hence the gaps.
There used to be a pretty good graphic on the net that showed the whole process, but it seems to be gone now, so I'll have to settle for something from QinetiQ

The shorting out is mentioned in the grill/slat armour section, and the warhead deforming (strangulation) is mentioned later on.
AMV is a modular design so you get them with more racks and tie points if you want to but this batch highlighted has been designed with arctic conditions and forest terrain in mind.
ReplyDeleteGetting your gear covered in water that freezes later is bad. I found myself once banging a frozen (sim) LAW open with a magazine while we had a 52 tons tank on our ass.
Also its bad if a tree missed barely by the hull tears away all your stuff attached to tie points at the side.
This. It will be an important feature for the Americans too once they are fighting in Greenland, Canada or Siperia instead of deserts.
DeleteOr in the dense Jungle of a Tropical South East Asian Paradise Turned hot zone. US forces are global just because lately we needed deserts more then Jungles doesn't mean it's set in stone.
DeleteAs I figure there are Three reason you would want internal pack storage.
ReplyDelete1) Drag. If it's moving amphibiously it could come loose and then all that kit is gone. same as what Jokuvaan said. Trees and low hanging obstacles rip it free
2) APS.. a APS or Add on reactive armor would probably destroy any kit stowed on the vehicle.
3) Access and prevention of access. for the infantry it's easier to get at there gear stowed inside then having to pull it off the vehicle. and for some opportunist looking for valuables it's harder to get at.
Dumb question but what are behind what look like doors on the upper rear half of the vehicle?
ReplyDeleteWhat sea state can this thing swim at?
