The 100 mm gun-launcher 2A70 (GRAU designation: {{Lang|ru|2А70}}) 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, BMP-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.{{cite web|url=https://www.toutiao.com/article/7133877818844365316/ |title=大国善谋,武器维护保养换过时产品,26年后中国却玩出先进步战车 |website=Toutiao |date=25 August 2022 |language=Chinese}} The VN20 has a version with a 100-mm gun.{{Cite web |date=2023-02-11 |title=The VN20 Is The Largest Combat Vehicle In Asia {{!}} 21st Century Asian Arms Race |url=https://21stcenturyasianarmsrace.com/2022/12/03/the-vn20-is-the-largest-combat-vehicle-in-asia/ |access-date=2023-02-18 |archive-date=2023-02-11 |archive-url=https://web.archive.org/web/20230211155213/https://21stcenturyasianarmsrace.com/2022/12/03/the-vn20-is-the-largest-combat-vehicle-in-asia/ |url-status=usurped}}

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.[https://web.archive.org/web/20060621072410/http://btvt.narod.ru/4/bmp3mod.htm Боекомплект Бмп-З]
