Darn it, LoooSer beat me to it.

Edit: 3 freaking minutes. LOL.

Janes failed. "First" and "modernised"/  :mellow:

 

This is T-80UD, captured by rebels last summer.

Those T-80BVs were not modernised in any way, just repaired to make them actually work.

Both went nowhere with development most likely being cancelled. Bagira was to be an extremely long (55 caliber) 140 mm that could achieve over 900 mm of penetration firing a 7 kilo round at just over 1800 m/s. In all honestly that isn't very impressive considering the round only weighs 7 kg. Vityaz is more...in the air so to speak. Little to no information on it, except for that it could fire a 5 kg rod at around 2000 m/s. My guess would be that it is similar in theorey to the 2A82-1M; uses a long barrel, higher pressure chamber, and more powerful propellant to up penetration.

The important part here is that no current or planned vehicle uses them (they aren't even marketed...) and as such, both have been cancelled IMO.

For now Ukraine continues to use the KBA-3, which is just their indigenous 2A46M.

Thanks; that's about what I'd heard before.  Nothing on breech pressure, whether the guns used unified ammo or two-piece, or other essential technical data.

Ukrainian tank industry is well know for presentation of Soviet projects as Ukrainians. Both those guns were very likely based on Soviet counterparts, which were under development for Soviet future MBTs in 80s. And because those MBTs are still secret, information about guns will also be non-existent outside of state offices.

It would be impressive if the gun wasn't 140 mm. The other European 140's could fire longer projectiles, faster, with more penetration. 2A82-1M also matches its ability (if not surpassing...) while being much smaller in length and caliber.

2A82-1M abilities are unknown. We still don't know actual perfomance of ammunition for this cannon.

But claimed figures have pegged it to be ~20% more powerful than 2A46M variants and the L/55 120 mm. Vacuum information suggests it will penetrate at least 900 mm of RHA at two kilometers, through 2A82-1M.
