Шаблон:Infobox Weapon

The 100 mm gun-launcher 2A70 (GRAU designation: Шаблон:Lang) is a model of low-pressure rifled cannons designed in the Soviet Union by the KBP Instrument Design Bureau. Integrated into Bakhcha-U and Sinitsa turret modules, the gun equips the BMD-4, BMD-3, and BTR-90M infantry fighting vehicles. It is capable of launching the high-explosive fragmentation (HE-FRAG) 3OF32 and 3OF70 projectiles, as well as the 9M117 Bastion gun-launched anti-tank guided missiles (ATGM) and related systems.

China produces a similar gun used on the ZBD-04 IFV, using technologies licensed from Russia in 1996.[1] The VN20 has a version with a 100-mm gun.[2]

History

By no later than 2006, the then-standard projectile 3OF32 was found to be underpowered. Being modified from the WW2 52-OF-412 projectile of the 100 mm field gun M1944 (BS-3), it was designed to withstand a higher ballistic-performance gun and thus has too thick walls and insufficient explosive filling.[3]
