Yeah, I read Kotsch's explanation and saw the patent, but it seems weird to me. I made this GIF of a T-90A (from the TV Zvezda show, episode "diary of a tanker"), and it doesn't show what Kotsch described.
 

It seems to give a misunderstanding. The sketch is part of a russian patent. And it is embedded in a general view to autloaders. There are no assignments to a special tank.

Pardon me, but I'm not sure what you mean. Do you mean that the machanism from the patent was just a prospective solution that was not actually used? Or do you mean that the patented autoloader can be used in any T-72/90 tank and not just the T-90A?

So in the end, what are the differences between the T-72B and the T-90A autoloader ?

5 names but 6 rods. :(

 

BD26 predecessor to L26 ? L26 have uranium or tungsten core ?

judging by drawing, it's more like L27 imho...

CHARM U 3/4 Ti
 

BD26 is a 120mm APFSDS projectile which incorporates the latest tungsten-nickel-iron penetrator technology to achieve an increase in penetration performance of the order of 15% over the current in-service L23(OE)APFSDS projectile. BD26 is designed for operation with the existing Lll ordnance and L8 charge.
The penetrator is made from a Tungsten/Nickel/Iron alloy (TF49P) with a 6 blade steel tail unit and steel nose tip. It is located in a 3-segment aluminium alloy saddle type sabot with a buttress form screw thread which provides the 'drive' between the sabot and penetrator.


Any pictures ?

Based on my research, it looks like the 3BM11 122mm APDS round was designed (intended?), only for the M-62C main gun of the T-10M, not the D-25T, D-25TA/D-25TS, or D-49. There are discussions around the Net, however, that report a sub-caliber round was developed specifically for the D-25T and the D-49.

Does anyone know anything about a sub-caliber (APDS) round specifically intended for the D-25T and D-49?

M62 have 3BM7(never seen any photos or schemes, but judging by some sources it uses same alloy as 100mm 3BM8 APDS - W-Ni 8) and 3BM11(W-Ni 10 alloy)

 

don't know about D-49, seriously doubt  that D-25T ever  had APDS

Is there info available on Chinese-made gun-launched ATGMs? NORINCO's website doesn't show anything. I know they purchased the Russian "Bastion" system for the ZBD04 but do they produce their own version too? And what about the 105mm version for the ZTL11, WMA301 Assaulter etc.?

Thanks Jim. Yes the Chinese rounds are based on the Russian 9M117 and 9M119. In the last picture the latter is called GP125 but I found also the designator GP7. The 105mm GP105 is almost certainly a scaled-up 9M117.

please ident these rounds

.10799755_856251277748277_1313173963_n_zp

APFSDS look longer than either M111 or M725....

 

Wonder if those are The M48 A5's we transitioned from in 84?

Without knowing where that came from, that sounds like Operation Jericho, which was an effort to get an operational emergency round to Challenger units in Operation Granby in 1991. I believe they introduced the under development L26 fin round and made it compatible with the L11 gun and the bagged charges they had at the time. It was strictly an interim measure to deal with T72s if they turned out to be as well armoured as Soviet ones were. As it turned out, I think the only T72 the British army encountered they nicked off the Americans, and it was probably never used.  Looking through the Challenger 1 manual, there were a number of amendments made in 1991, which may well have had been related changes. There were for example armoured charge bins, and ive got a sneaking suspicion there may have been a new charge for it too.

 

There is a bit about this in the Haynes Challenger 1 book and the Osprey book on the same if its any interest. It does show what can be achieved when somebody holds a gun to the MOD's head, maybe the army shoudl do it more often.
