It has some bursting charge.

Which is more than 100 gramms of healthy AX-2-X, so not far from 200 gramms of TNT equivalent. So rougthy two RGD-5 grenades for each BR... Yeap, a healthy addition to IED.

I believe that it would definitely shatter the base of the shell and propel at least some of the fragments to a lethal velocity, but generally speaking, the bursting charges at the base of AP shells don't actually turn the shell into a grenade. It merely guarantees that the entire shell will be broken apart after perforating some armour, because the base often remains intact even if the nose is shattered by the interaction with the armour. Personally, I doubt that it would have made a noticeable contribution to the power of that IED.

Won't make noticeable, but still will make a change. Esp if properly placed (to ensure correct initiation and fragmentation.

Guided 125mm shell with large thermobaric warhead (booster is replaced with larger warhead, limiting range):

Passive target contour-based = image recognition?

Yes. Simple image processing to find edges can be called contouring. Find the edges of the thing that you're aimed at, then hit inside them, I guess.

You do simple convolution processing for edge detection. Quick and dirty provided you have contrast.

No, this is actually not what is (and was) in development. Sokol-1 (Falcon-1....now it is Falcon-5, stage of development).

For that book thay took a fake image )))

....

Design borough  Tochmash (named after A. E.  Nudelman) developed in the 80s guided missile for a future Soviet tank (Molot).  The theme smoldered for decades and in a recent UVZ report popped up under the name Sokol-V (Falcon-V).  Now already trimmed for 125 mm 2A82-1M in the T-14 object (see UVZ Annual Report for 2018).

With a multispectral homing head.  The work agreement was concluded with the Design Bureau in 2013 the completion of the work was planned for 2016. Apparently, everything was delayed if, in 2018, only stage 5 was reached and “approval of the applicability of the Sokol-V product in the 2A82-1M system” (according to the report).

Details (rus) – https://btvtinfo.blo...og-post_26.html

Modern Russian and Chinese rounds are 900mm + at point blank right ?

No, they are not. Realistic estimates put them at 600 to 700 mm at 2,000 m or at best 800 mm point blank.

Current Russian tungsten APFSDS, for the latest variants of the 125 mm D-81T gun, have a penetration of 640 to 660 mm into 60° sloped armour steel at 2,000 metres. The penetration fo the DU variant is claimed to be 740 mm under the same conditions.

 

 

Thought was interesting and just a little tid-bit but recently some screenshots of a program saying that the 125mm cannon on the Type 99A can penetrate 680mm at 2000 meters.

Vacuum 1 is listed above as 450mm of 60 degrees inclined plate, or 900 mm LOS.  The path length will perhaps be somewhat less though.

I compiled some available data, they seem to agree somewhat:
