Too late for CMBS timeframe, but here's the US M1147 AMP

[John Kettler]

Would say it falls somewhere on the spectrum between evolutionary and revolutionary, since multipurpose projectiles have been around for as long time. See, for example the old Rockeye, which went off as HEAT if it hit something hard and HE Frag if it hit dirt, mud or snow. This projectile has four separate and distinct operating modes. In CMBS, the Russian T-90AM has a projectile with some of the capabilities of the M1147 AMP, but not all of them.

Seems like it continues through the truck even after exploding?

The tail section continues forward thanks to its momentum; the same thing happens with ATGMs, after a hit the tail section leaves an impression on the armor that is visible to the naked eye.

Thanks, yes that makes sense. I noticed now that the same thing happens in the airburst video. I just thought the explosion would either demolish the tail or knock it off course, but it's clear that's not the case...

Since it bursts into multiple warheads will that defeat the new active defense systems on eg: tanks?

I think that's actually APFSDS rounds dude:

M60 turret penetration by a DM-63 APFSDS round

 Doubtful.

It's not multiple warheads, it's a MEFP. 

Those smaller multiple penetrators wouldn't be powerful enough to seriously trouble a modern(ish) MBT, even the more powerful single penetrator mode might struggle with a truly modern MBT, hence all those sabot rounds in the othe half of the ammo rack.

Arms manufacturer demo reel music is the best. Not as good today as in the 80s and 90s but it's still jammin'.

[SergeantSqook]

Isn't this already in CMBS

 

"The Advanced Multi-Purpose (AMP) round will replace most other Abrams rounds, including HEAT and canister rounds, allowing for simpler logistics and more effective battle loads. The AMP round uses an ammunition data link and a programmable fuse to act in a variety of roles on the fly, allowing a single round to effectively engage a wide variety of targets. For example, after lasing the distance to a target, the AMP round can be programmed to airburst over an infantry target, negating the protection gained from walls, ditches, or earthen slopes. With a delay fuse setting the AMP round can also be used to engage bunkers and fortifications, buildings or to breach walls."

? This is completely different. Another thing.

I could also tell about these as well, they leave different marks depending on armor thickness.

Can you show me an image, I've never noticed it.

Couldn't find anything online, will not upload classified.

None at all.....Suggests it's kind of an uncommon phenomenon then?

No, it is common. Just nobody makes high quality close up pictures of ATGM post -hit signatures. Nobody of the ordinary soldiers.

Strange, I found lots, starting from Yom Kippur and onward to the recent fighting in Syria.....Just none where I could see the imprint of tail fins.

Its not the fins that make it, but the rocket engine casing, it makes a ring like impression. (ATGMs, not RPGs)

Developer promo videos have a history of targets being packed with explosives to make the results look more 'Hollywood'. Its not outside the realm of possibility that the round passed though those two tissue-thin door panels without even realizing it hit anything. I recall drones in old promo videos mysteriously 'exploding' while being fired on by AA guns that weren't firing HE rounds... and the rounds didn't actually strike the drone. But it did look spectacular.

Knew, as I said, the T-90AM had a special purpose projectile, but didn't recall the AMP was in the game and didn't have manual to hand, either. Looking on the bright side, now people can see for themselves what it is and how it works.

Sgt.Squarehead,

Man, those fins are tough! Would never have expected to see that occur. Great pic!

Looks like a worse version of the 15 year old Bofors 3P round, but for 120mm

https://sempermiles.se/wp-content/uploads/2020/10/baes_ds_Bofors-3P_redesign_digital-8.14-1.pdf

The Mk 3 stealth gun was built in our Stealth Visby-class corvette - Wikipedia  Wich was the real deal! From the Smyge stealth test wessel from 1991  HSwMS Smyge - Wikipedia Sweden was an early adopter of stealth technology! And the US addapted the 57mm Stealth gun as the Mark 110 Mod 0 57mm gun on the LCS and Coast Guard wessels! https://www.navy.mil/Resources/Fact-Files/Display-FactFiles/Article/2167940/mk-110-57-mm-gun/

Armorgunner,

Had only a faint memory of the 40 mm round you showed, but the 57 mm is emblazoned on my brain. Always wondered why we didn't rush out and adopt it. And I recall that the Germans were hard at work on a 57 mm armed IFV back in the 1980s.

This has some material not in the above AMP video, including some in-turret sequences. Being able to go from five different ammo types to two is a huge help to the loader. And the AMP is the answer to a tanker's prayer when it comes to the battle carry/up the spout round, since it can deal with so many different types of targets. Per the video, only the M1A2 SEPV3 Abrams can use the new round, because of the M1A2 SEPV3's upgraded FCS. Do not know whether or not that's the case in CMBS. All you need to know about US weapon development and procurement is encompassed in the description of the round: "over 15 years in development". For a cannon shell, people!
