The 3UBK10M-3 is the BMP-3-specific 100 mm round for the 9M117M Kan laser beam-riding anti-tank missile, fired through the 2A70 gun-launcher in the Basnya weapon system. Rosoboronexport and Army Guide describe a 22.9 kg round with a tandem shaped-charge warhead, 100-4,000 m range, 600 mm armor penetration, and manual guided-round loading on the BMP-3.

Variants

The 3UBK10M family uses the 9M117M missile with cartridge or round suffixes that identify the launch gun and platform. The -3 suffix is the BMP-3 100 mm 2A70 gun-launcher member, while the later 3UBK23-3 Arkan page covers the extended-range BMP-3-family round with the 9M117M1-3 missile.

Firing Weapons

The 3UBK10M-3 round with the 9M117M guided missile is tied to the BMP-3's 100 mm 2A70 gun-launcher rather than to a stand-alone missile launcher.

Rosoboronexport lists the 3UBK10M-3 round with the 9M117M guided missile as ammunition for the BMP-3's 2A70 gun-launcher, and Army Guide describes the complete Basnya weapon system around the 2A70, 3UBK10M-3 round, and 9M117M missile.

Loading context

Army Guide states that 100 mm high-explosive rounds are autoloaded in the BMP-3, while the laser-guided projectiles are manually loaded and eight guided projectiles are carried.

Round Family And Launcher Context

The 3UBK10M-3 entry is best read as a BMP-3 ammunition component inside the wider 9M117M Kan family. The same missile family appears in cartridges for other 100 mm and 115 mm launch guns, but the -3 round is the BMP-3/2A70 configuration documented for this page.
