To improve combat effectiveness against modern and future tanks, the 100–115 mm rounds with the 9M117 guided missile are subjected to modernization. The works resulted in the development of a family of rounds comprising the 3UBK23-1, 3UBK23-2, 3UBK23-3 designed for firing from the T-55, T-62 tanks guided weapons and from the BMP-3 IFV.
The 9M117M1-3 Arcan rounds can reability destroy tanks (such as the M1A1, Merkava-3, Leopard-2, T-84), that are the basis of the tank parks in the most advanced countries, at course angles of more than 30°. The engineering solutious realized in the Arcan are used to update the 125-mm rounds. The weight-and-size dimensious of the 125-mm round are analogues to the series-produced round. Its operation and feed into the loader are similar to those of the series-produced version.
Currently KBP is engaged with the development of the 105-mm round for the L-7 type gun.
