T-34/45

A couple of months before the start of the war, the chief of GAU, marshal Kulik, advocated on the basis of the findings of the intelligence to the soviet tanks were quickly rearmed on the caliber of 107 mm was, however, from the masterfully planted the information supplied to the Germans.
With this the people's commissariat of armaments headed by Vanikovem, did not agree. Pushed for 45 and 76 mm, with the proviso that in the future he will pass on the caliber of 85 mm. Their proposal, however, Stalin did not approve, and preferred to Kulik. Therefore, the factories for the production of works at the beginning of the war přeorientovávaly on the new cannon of large calibre, and basically didn't exist yet. This led to considerable delays in the supply of, how works so rounds of existing calibres, into units of the DRRA. Therefore, there was a re-reorientation of the cannons calibre 45 and 76 mm. Began to rapidly produce not only in the artillery plants, but also in civilian operations.
At this time also arose the idea, to arm units of the combined caliber cannons, tanks T-34. This was based on knowledge of the shooting tests, which have found that the disposal of the corps and the pillbox is needed 2-3 shells caliber 45 mm, as well as grenades caliber 76.2 mm. Because in the initial period of the war was considerably more of these objectives than anti-tank guns and tanks, should have a battalion of tanks T-34 two squads armed with cannons of 20 K, 45, of the 200 bullets in the vicinity of the diameter (this was armed with 1 prototype A-20 and A-32.2), and the platoon with cannon F-34, caliber of 76.2, 77 bullets in the vicinity of the average.
"30 serial T-34 September production of" 1940, it was already armed with a cannon L-11, before passing the military. Three serial participated in the endurance trials, and one was sent to VAMM, apparently also with a cannon L-11.
Only 10 tanks, this means, according to the then tabular conditions DRRA is these two companies and you probably were armed with cannon 20 K, as the T-34-45 vz. 40, but probably only with the 100 hub in PP.
These tanks T-34-45, however, steps have been made intentionally and not, as claimed, as a stopgap !!
It is known to me only photos of the tower from the T-34-45, as part of a German armored train armed for use of captured equipment.
(Taken 17.7.1942 at the Voroshilovgrad - the Southern front)
The tower is actually from a T-34ky and not from And-32, the looked somewhat different!!.
