To extend the operational range of the T-80, additional fuel tanks can be mounted at the hull rear, which can be quickly jettisoned if required. A large circular container mounted on the turret rear carries two snorkels for deep fording operations. The larger one provides an air intake for the gas-turbine, with the other being fitted onto the radiator grill. The T-80 was also the first production Soviet tank to incorporate a laser range finder and ballistic computer system. The daysight can be used at night for launching ATGMs if the target is illuminated.
Thermal sights are available for installation which permit night launch of ATGMs.
There are thermal sights available for installation which permit night launch of ATGMs. The BK-29 round, with a hard penetrator in the nose is designed for use against reactive armor, and as an MP round has fragmentation effects. The electronic round fuzing system for Ainet rounds is available for other tanks. The round is specially designed to defeat targets by firing fragmentation patterns forward and radially, based on computer calculated settings from the laser range-finder and other inputs. Targets are helicopters and dug in or defilade priority ground threats, such as ATGM positions.
