T-34 The T-34 is a Soviet medium tank introduced in 1940. When introduced its 76.2 mm (3 in) tank gun was less powerful than its contemporaries while its 60-degree sloped armour provided good protection against anti-tank weapons. The C ...

tank's F-34 76.2 mm tank gun was replaced by a more powerful 85 mm gun. This rendered the year-old SU-85 tank destroyer effectively obsolescent, since its D-5T 85 mm gun was now also fielded by a more flexible medium tank.

F. F. Petrov Fyodor Fyodorovich Petrov (russian: Фёдор Фёдорович Петров) (16 March 1902, Venyovsky District, Doktorovo, Tula Governorate – 19 August 1978) was a Soviet Union, Soviet artillery designer. References

Armor penetration performance increased further with the development of APDS (Armor-Piercing, Discarding Sabot) and other more modern ammunition types after WWII. A more effective high-explosive shell was also developed after the war, taking advantage of the larger 100 mm bore. It was originally designed to equip the

tank destroyer as the D-10S (for ''samokhodnaya'', 'self-propelled'), and was later mounted on the post-war T-54 main battle tank as the D-10T (for ''tankovaya'', 'tank' adj.).

Versions of the D-10 were installed on new tanks as late as 1979, and thousands still remain in service in various countries.

Anti-tank ammunition available from World War II until the late 1960s was based on the UBR-412 round, including the BR-412 armour-piercing high-explosive projectile, with the ballistic-capped BR-412B and BR-412D ammunition becoming available in the late 1940s. There was also a D-412 smoke shell. In 1964, the NII-24 research bureau started design work on an improved 3UBM6 anti-tank round. In 1967 the 3BM6 hyper-velocity armour-piercing discarding-sabot round (HVAPDS) entered service: At a range of 2,000 m, it could penetrate 290 mm of flat armour, or 145 mm of armour angled at 60 degrees from the vertical. It was later replaced by the 3BM8 HVAPDS projectile, with a

The missile is very expensive, about half the price of a T-55M tank, but allows the venerable 100 mm gun to engage modern main battle tanks. Missile ammunition includes: * 3UBK10-1 (9M117 ''Bastion''), penetrating 600 mm at up to 4,000 m * 3UBK10M-1 (9M117M ''Kan'') tandem warhead, penetrating 650 mm at up to 4,000 m * 3UBK23-1 (9M117M1 ''Arkan'') extended-range tandem warhead, penetrating 750 mm at up to 6,000 m * 3UBK23M-1 (9M117M2 ''Boltok'') extended-range warhead penetrating 850 mm at up to 6,000 m
