New amphibious "surfing" IFV

Does the bow plane provide protection against HEAT?

The "bow plane" plane provides lift while moving through the water. A greater part of the vehicle is out of the water => less drag => more speed.
I'm quiet sure it won't stop a tank HEAT round. Otherwise the vehicle would become to heavy. And that's against it's right of exsistence.

Yeah I think I pretty much figured out the "surfing" part. But you seem to answer my question without knowing anything about HEAT. There's a game you can play where you disrupt the jet (reactive armor) or make it detonate too early (a fence or shield external to the armor). The fence was first tried by Germans in ww2, reactive by Israelis. Nowadays they have these "tandem" warheads that trick the trick. I really don't know more to say more.

Can anyone explain how the tandem's work? How would any HEAT warhead preserve its detonation until it reaches the "real" armor? What if it hits a spray of water jet? Helps the amphibian a lot if HEAT can be sprayed away with seawater.

Um, seawater? I highly doubt it.
Tandem warheads are just warheads placed one in front of the other. The one in front is usually much smaller and detonates on impact. The real warhead behind it detonates after a slight delay. The defeat mechanism of reactive armor isn't to "destroy" the plasma jet (kind of hard to do that when the jet will go through the metal you throw at it), but to damage its integrity through sheering forces, for example, breaking off the tip. Reactive armor is typically detonated by the plasma jet itself, so it won't be set off, by say, HMG bullets. In a tandem warhead, the small shaped charge in front sets off the reactive armor and the rear warhead detonates a bit later, after the effect of the reactive armor has passed, to attack the main armor. But now-a-days there are reactive armor which are designed to fight tandem warheads, and I think a Swiss company makes triple warheads, etc etc.

What about the fence then. Your little warhead isn't going to make a hole big enough or fast enough to let the big one through unharmed? It does seem fence is not 100% effective I'm not sure why.

If you hit water at 100km/hour it's deadly to you. The missile will be flying several times faster than that. If I can put up a big enough spray at the right place right time I can stop the missile.

Hm, if you look at the pics, you'll see neither ERA nor that cage on or around the bow plane. And it's rather thin, too.
If you ask if ERA or a cage could be added, it's something different. But I don't think so, at least when you use the vehicle in the amphibious role. Since the plane is in a different position in the water and on land, you'd have to adjust the cage. And I think cage and ERA would harm the seagoing capabilities of it. But that is probably better answered by someone else.
The cage is mostly to counter the threat of the very common RPGs I think. A modern ATGM would punch through the armor of a such protected vehicle (in or below the armor class of an amphib IFV) anyway.

And I don't believe we will see amphib IFVs spreying water against a missile to defeat it.
What your are looking for is:
APS and APS.

Notice the waterline markings on the second picture. I would agree with pointblank that this might be a newly developed dedicated amphibious fighting vhecile.

BTW, these are some very high quality pictures taken by professional level cameras. There is no camera shake or grainy lines usually present in civilian "spy cams" Are those taken during actually testing or exercies by the media? If they are, it may suggest that these vheciles are already in PLA service.

The black and white pics are PS'ed images, using photos that originally featured the American AAAV/EFV for the background... Nevertheless, they are interesting, as they show what the vehicle looks like in action.

That indicates to me then that this vehicle is not yet in service, but prototypes exist, and that the manufacturer is most likely marketing the IFV to the PLA and export customers.

Umm, why don't you back that up with something? You can't.

Compare the features in the color photos with the b&w, even compare the camouflage, they are the same vehicles.
