Jane’s has learned details of the mission systems mounted in the Russian T-90MS main battle tank (MBT), including the fire-control system (FCS), sighting and observation equipment, and vehicle-protection systems.

Elements of the Kalina FCS – which is used in conjunction with the T-90MS’ 2A46M-5 125 mm smoothbore gun and UDP T05BV-1 remotely operated weapon station (ROWS) – include the Remeshok identification friend or foe (IFF) system and gun control, stabilisation, and electro-optical systems. Within the FCS, data transmission between the different components is undertaken through a MKIO multiplex data channel.

The FCS is linked to the Sosna-U multichannel gunner’s sight and the Falcon Eye panoramic commander’s sight. A back-up direct observation sight is also fitted. The Sosna-U is capable of using a laser channel to guide anti-tank guided missiles, as well as provide 4x and 12x magnification and twin-axis stabilisation.

The Falcon Eye is similarly stabilised and features day and thermal channels. Both incorporate a 7,500 m-range laser rangefinder and are capable of identifying a tank in daylight at a range of 5,000 m and 3,300 m in poor light conditions. Jane’s has learned that the laser rangefinder used by both sights incorporates a ‘foreign matrix’ of unknown origin.

The sighting systems are coupled to a 1V528-2 fire-control computer, incorporating meteorological data from a turret roof-mounted wind and temperature sensor mast and internal atmospheric pressure and projectile temperature sensors. Additionally, the computer incorporates data from a 1V216-2 ammunition selection computer to enable different ammunition types to interface with the 1V528-2.

All the information fed into this is presented and altered using the BV1-2 interface panel; this allows the commander to manually alter input data if required, as well as operate the different observation and targeting sensors, including the roof-mounted panoramic ROWS.

Additionally, the Kalina FCS is the first Russian system of its type to incorporate an integrated external surveillance system.
