Rheinmetall's 25 x 137 mm PMB 090 APFSDS with tungsten penetrator defeats 35 mm steel sloped at 60° at a range of 1,000 m, although older documents from Oerlikon list the same penetration at 1,200 m distance (probably a result of different penetration criteria).

 

The 25 mm APFSDS from GD should achieve a very similar penetration, maybe a tiny bit lower due to its (negibly) lower velocity (5 m/s) and shorter penetrator.

This display was present at the German Army Open Day at the Wehrtechnische Dienststelle 91 in Meppen. I did not take a picture, because the doors were obscuring the subject. They had a lot of current DM53 and DM63 rounds on display, either complete or cutaway. Very interesting.

They also did live fire demonstrations with the LARS, Puma, Leopard 2 and PzH2000. Fun to watch. A Leopard driving down range, firing a shot is quite impressive.

It appears the steel isn't these blocks, but thin sheets between the blocks. If you look carefully you can see each block is split in two. These are perhaps 2 large chunks of some soft material holding a very thin steel plate, a few centimeters at best. Although we do see some spalling.

Yeah it is very misleading by using such wide posts on the ends.

I like the Sabra prototype they have parked there. Looks like the one that was in many of their brochures a decade or so back.

Yeah that was one of the evolutions in the Sabra family, had it been purchased outside Turkey, or if ties with Turkey wouldn't have been severed.

 

It was seen not too long ago with a gun. I wonder why they took it off.

It's probably used as a gun-testing platform for upgrades to the 120mm gun or for ammunition.
A damaged barrel from a failed test or just wear from over-use would see it removed for inspection before replacement.

Avco Systems Division XM815 105mm HEAT-MP projectile. 

 

Its muzzle velocity of 1174 m/s was the same as that of the M456 projectile which it was designed to replace but, because of the lower drag of its pointed nose body and the stability provided by its slender pop-out fins, it proved significantly more accurate.

The UK wants a 'swimmer' round for its 30mm guns. Developed by Nammo, this is an only slightly modified APFSDS - the sharp tip is replaced by a blunt one.

The round is intended for Type 23 frigates, and will replace standard APFSDS rounds as it is considered to have the same penetration power but with an additional role.

   NI (sorry) article about T-80BVM getting newer shells, one interesting part:

Quote

The Svinets-1 has a tungsten carbide core, while the Svinets-2 uses depleted uranium. according to the Below the Ring armor site, published by a pair of Dutch defense experts. A 2016 post speculated that Russia might have been producing these special rounds for several years as replacements for existing tank ammunition.

   What is this "below the ring" site? Clicking on link reveals that it is Below The Turret Ring article from 2016, lol.

      I see many knowledgeable members here so i decided to make an account to ask some question
      According to many historical accounts, the armor of WW II battleship is very thick: can be between 410-650 mm of steel
      Thick enough that they can even resist penetration  from 12-16 inch canon 


       
      Compared to these massive round, it is probably obvious that missiles such as Harpoon, Exocet will do little or nothing against the armor belt: No penetration and probably nothing more than a small dent.
      Anti tank missiles such as AGM-65, AGM-114 or Brimstone can penetrate the armor but all their warhead will do is penetrating a tiny hole into the massive battleship, it likely will hit nothing significant given that a battleship have massive volume of space). Furthermore, i heard space armor is extremely effective against HEAT warhead as well).
       
      But what if the two are combined? HEAT + explosive warhead: aka BROACH.
      With a frontal shape charged and secondary follow through bomb
      This is the working principles of the system:


       
      BROACH was designed to help small cruise missile penetrate bunkers. So i have some question:
      1- Because concrete and soil are very brittle, unlike steel, I think the precursor charge likely much drill bigger hole in them than it can drill on steel armor belt of a battleship, so even if we use missile with BROACH warhead to hit a battleship, it won't drill a hole big enough to allow the secondary warhead to pass through. Is that a correct assessment?
      2-  Looking at the cutaway of the missiles. How come the detonation of the frontal shaped charge doesn't damage/destroy the secondary warhead or at very least propel it to the opposite direction? 
       
      3-  Can supersonic missiles such as Agm-88 (Mach2) , Asmp-A (Mach3) , Rampage , Asm-3 (Mach 3) , Hawc (Mach 5) penetrate the armor belt of a battleship? or they simply don't have enough velocity and density?

      M1 CATTB
      pic from TankNet.
      I feel uncertain whether its cannon's caliber was 140mm or not, I found a figure at the document AD-A228 389 showed behind, which label the gun as LW 120.But in many ways I've found its data in websites all considered to be 140mm.

      AFAIK,the first xm291(140)demonstrator was based on xm1 tank, and the successor was the''Thumper'' which was fitted with a new turret look like the CATTB but still m1a1 hull(Maybe it was CATTB's predecessor? )

      I will really appreciate if anyone have valuable information to share

      Hello all,
      I apologize for the fact that my first post is a question. I am a Dutch collector of medium and large calibre AP ammunition and I recently bought an 105mm APFSDS-T projectile, that is marked with the designation DM53. The 120mm DM53 is well known, but I cannot find any information on the 105mm DM53. I do know the IMI M426/DM63 round exists, for I have seen pictures of that, which would indicate that a DM53 would exist as well, in accordance with the way German ammo designations go. Questions to Rheinmetall, the Bundeswehr and various collector groups have remained unanswered. 
      Among the experts here, is there anyone who has information on this type of APFSDS-T Round?
      Thank you in advance,
      Domichan

      I realize that sandbags provide little to no armor protection, but soldiers still used them on tanks. Would they mitigate the effects of HE warheads, or the blastwave of HEAT warheads?
