T-72M2 Slovak Moderna T-72 most special variant
Notes: The Czechoslovakians, and later the Czechs and Slovaks, have been building and employing the T-72 and its variants for almost two decades now. Their local variants, both before and after the fall of the Iron Curtain, often had different electronics, fired locally-designed ammunition, had different armor suites, and different sensor suites, amongst many little and big differences.
A large portion of the Czech and Slovak tank forces consist of locally-manufactured and modified versions of the T-72M1 and T-72S. However, the Slovaks have come up with a radically different version of the T-72, based on a T-72S hull with a heavily-modified T-72M1 turret mounted on it. Two versions of these very-different T-72s are built, designated the T-72M1 Moderna and T-72M2 Moderna. Though there are some rumors of Slovak use and they are marketing the design heavily on the international market, there are no confirmed users as of yet.
The first model, the T-72M1 Moderna, was meant to be sort of a tank that also conduct effective short-range air defense as well as have a lighter weapon for use against light vehicles and personnel. Two this end, the T-72M1 Moderna turret retains it’s primary armament – but on each side of the turret, a 20mm Oerllikon KAA autocannon is mounted. The autocannons have independent elevation and depression from the main gun (but can’t be turned in different directions); depression is about the same as the main gun (about -5 degrees), but the elevation limit is just short of straight up. Different sights are used for the autocannons and the main gun/coaxial machinegun; the commander has controls for both the autocannons and the main guns, as does the gunner, and using both the commander and gunner, the main gun or coaxial machinegun and autocannons can be firing simultaneously. The sights for both weapons are separate, but approximately the same in capability, and both are stabilized equivalently. The T-72M1 Moderna has a laser detection system that can automatically one or more of the five smoke grenade launchers on each side of the turret. The gunner and commander have thermal imagers and other upgraded night vision devices, and the main gun and autocannons have separate laser rangefinders. The ballistic computer has also been updated to be able to assist both the main gun and autocannons. The T-72M-1 Moderna can mount ERA on the turret front, glacis, and hull sides; the autocannon mountings do not allow for the installation of ERA on the turret sides.
The T-72M2 Moderna works from the same concept, but the 20mm autocannons are replaced with a twin autocannon mounting on right side of the turret. The autocannons on the T-72M2 Moderna are 30mm 2A42 autocannons instead of the 20mm KAA autocannons, and this allows the autocannons to be used against light armor as well as air targets and light vehicles. Sighting equipment is slightly different, and the ballistic computer is reprogrammed for the new autocannons and for general accuracy. The mounting of both autocannons on one side of the turret also simplifies the feed system and concentrates their fire.
The T-72S-based hull of the T-72 Moderna uses side skirts hade from a plastic/aluminum sandwich instead of the Gill armor of the standard T-72S. Like the T-72S, the floor armor is strengthened and the autoloader holds 22 main gun rounds. The Moderna’s main gun is a 2A46M, with ATGM capability, though ammunition carriage is reduced in order to carry ammunition for the autocannons.
Twilight 2000 Story: The T-72M1 Moderna does not exist in the Twilight 2000 timeline; the T-72M2 Moderna does, however, but it is called the T-72M1 Moderna.
Slovak 125 mm Modernized Tank Gun 2A 46MS for T-72 M2 MODERNA,
Unlike other projects of upgrading T72 Slovak MBT upgrade also focused on complete modernization of the main tank gun.
2A46MS smooth bore tank gun is a modernized version of 2A46 gun used in T-72 MBT series. 2A46MS is designed for the Slovak T-72 M2 modernized tank to increase its efficiency and accuracy of fire. The modernized gun is one of the most important elements of the whole modernized tank as it provides for increased first hit probability that is essential on a modern battlefield of today. Increased accuracy secured through 2A46MS modernized gun is closely connected with T-72 M2 combat efficiency and survivability.
2A46MS gun maintains the same mechanical interface with the turret of T-72 MBT as the original 2A46 gun. Increased accuracy of the modernized gun was achieved by:
redesigning the breech block of the gun to make it more symmetric,
decreasing resistance of the recoil break while projectile is moving in the barrel,
removing the recoil break axis below the main gun axis in the azimuth plain,
using two recuperators acting against each other and placing them above the main gun axis.
First hit probability of 2A46MS modernized gun compared to the original 2A46 gun was increased by 23%. In conjunction with a FCS of T-72 M2 MBT this value was even more enhanced. T-72 M2 MBT with 2A46MS modernized gun was qualified for the Slovak Army.
