Sosna-U fire control system in a T-72B3

These photos are rather interesting because they show the “insides” of T-72B3, the upgraded version used by the Russian Army. Large numbers have been acquired in recent years and they were used in the Ukraine conflict. The main improvement is the Sosna-U FCS (Fire control system), which has a thermal sight. The first image shows another T-72 as seen by the thermal camera. The second image shows a screen for the driver.




The third image shows the parameters included in the FCS. In previous versions many of these were not included. Now they are calculated automatically. The first 5 are:

- Temperature of propellant.
- Temperature of air
- Atmospheric pressure.
- Wind speed.
- Lateral inclination.
