I find it amazing how much damage this round causes to the plate and the fact that has more kinetic energy than most 125mm APFSDS rounds. What target should I test it against next?
I'm always interested in impacts of kinetic projectiles against light armor at extreme angles. It used to be taught to angle your armor against incoming fire; nowadays, thin side armor isn't reliable against modern rounds and it's taught to face threats directly in order to not expose it. Could we see this round against a contemporary's side armor at glancing blow angles?
@@spytf2693speaking of water I wonder if MBT fills up their spaced armor with water if it could reduce spall and sharpnel,but then it would increase the weight by an unreasonable amount
Would it be possible to test this same round versus some of the early spaced plate arrays like T64 or t72? But maybe at a slighty short range? 1500 meters or 1000
I definitely would like to, but the textolite/composite in these arrays will be hard to calibrate correctly. I will need to look for penetration test data for the T64/72
The Soviets performed proper tests of the L15A4 against the T-64A, penetration limit was reached at 500 meters in the turret, 1,000 m in the upper glacis and at maximum range in the lfp.
This is really quite interesting and answers a question I had coincidentally planned to ask on your newest video no matter the content SY - the difference between APDS and APFSDS in terms of angled armour behaviour and why APDS deflects more like traditional solid shot with ricochets and the like, while APFSDS doesn't care much at all until its critical angle. I didn't know about the eroding vs fracturing and shattering difference, but this video makes it quite clear where that difference lies and how APDS started to evolve toward the type of armour interaction APFSDS has. Thank you for teaching me something new!
+1 i always wondered the interaction between HESH/HE and ERA with pressure view. I wonder how the pressure of the ERA blast will effect the blast from HESH/HE.
What would the point of that be? The amount of explosives in ERA is small, to the point where it causes no effects on the vehicle itself. Its also off-set from the vehicle, so any impact detonation of HE would be equivalent to it detonating on a barrier akin to spaced armor. It would be hard to render with nothing to really show for it. ERA of any kind is hard to do unless you have a really powerful rig and lots of time. I hope one day we get to see HEAT or APFSDS on something like Kontakt-5, at least something is actually happening there.. Wasting that effort of HE is just silly. All you gonna see is the ERA plates getting vaporized.
Another idea, it'd be cool to see some APCR tests against angled armour. For instance American, WW2 era 76 mm APCR vs a Panther's upper front armour. ngl I just wanna see if it's as bad as in War Thunder, I'd assume it isn't.
I used to be a Chieftain gunner during the 1970s so fired many of these. The gunner sight had two scales one for APDS and one for HESH. Not me but it had been known for a gunner to fire an APDS round using the HESH scale and then the APDS used to fly lol.

At 2000 meters, the angle of the shell would not be 0 degrees of incidence, the shell follows a ballistic trajectory and therefore it will hit the armor at an angle greater than zero.
Love these videos! I’ve always been curious about how tanks would fare against the US navy railgun, although idk if there’s enough data available to model it accurately

the problem of the IS-4M is not its armor but its 122mm gun, the gun is the same model as that of the IS-2, the 100mm of the SU-100 would have been more suitable .
Please redo the bob semple simulation showing 303 rounds going through the upper glacis of a tiger2. Of you change the uts to 5 MPa that should be sufficient.
I've been thinking about it for a while, but how would a trailing-telescopic APFSDS made of hardened steel perform at a realistic velocity? If it performs well enough it might be a viable cheap alternative to conventional tungsten APFSDS

Poor IS-4M. Tank armor really didn't age well after war with high velocity rounds and chemical rounds.
It's a 1946 tank. It is not the era of the HEAT-FS. This is the Chieftain it's being tested against, a 1960s tank.
its main issue was that it is too slow and heavy to cross bridges and keep up with planned soviet strategy
The IS-4Ms armor has always amazed me, it’s pretty thick…
"We haven't nailed it! "
"The target has been hit! "
That was very interesting, particularly how close it is to the real life comparisons. That round has a lot of energy behind it.
this might be resource intensive, but is it possible to simulate a hesh round against an array of ERA?
