Original gyro was replaced by a new model, which allows to obtain all necessary parameters for the FCS. These parameters were achieved by changes in the control circuits, reducing the will in the cannon and some changes regarding turret ring. Optimal figures were 0.3 mrad in elevation and 0.5 mrad horizontally. The original design of the stabilizer determined the mean amplitude of oscillations of stabilized cannon to less than 0.8 mrad in elevation and 2 mrad horizontally (turret), which did not give any presumption to meet the TTP needed by FCS. Turret is stabilized horizontally and gun vertically (So tank gun is stabilized both horizontally and vertically).Stabilizer crucially affect the final parameters of the FCS. Some of them retain original TPD-K1 day laser sight, either as a back up or as an alternative source of laser range. Fotona has developed a number of fire control systems for T-72 tank, tailored to the prospective customers’ requirements. Upon further research, I found the following external elements of the FCS on the Moderna, seen in real life photos, as well as on the ingame model. The Yugoslav connection I was never paying much attention to Modernas, before a certain post on these forums led my attention to this. Moderna, as we know it, has been prototype-completed in 1993. (Czecho)Slovak project Moderna was a Slovak post-breakup project intended to develop a modernization project for its vast fleet of export-variant T-72s. I have been asked to write about Moderna and it's FCS, so here we go.
