Ainet system:

T-80UK and T-90 MBTs are equipped with Ainet system that allows to electronically fuse HE-FRAG rounds to explode at predetermined moment of flight. In order to use the system the gunner must lase the target before loading the round into the breech. The round is passed by the auto-loader through an automatic fuse setter, which sets the fuse to explode at the correct distance; the fused round is then loaded into the gun and is ready to be fired. This system allows to efficiently use HEF rounds against hovering helicopters as well as infantry and light armor in entrenched positions, out to 4 km and more. All HE-FRAG rounds are compatible with this system, provided a new electronic detonator is used instead of the standard V-429E.
