The M-84AS prototype main battle tank is a modernized version of the M-84. M-84AS, sometimes referred to as M-84AB1 and M-2001, failed to advance to serial production.
Design The modernization gives an improved fire-control system with integrated day/night sight. The M84A1 gun is replaced with a similar but improved gun which, along with better control characteristics, enables easy and fast field replacement of the barrel. The M-84AS tank is able to fire 9M119M Refleks anti-tank guided missiles with laser guidance through the barrel, which enables accurate engagement of enemy tanks up to 5 km.
The M-84AS is equipped with imported Shtora-1 and Kontakt-5 that both enhance survivability of a tank. Kontakt-5 is an explosive reactive armor package (ERA) which offers improved protection against modern tandem charge warheads and kinetic energy penetrators compared to the earlier Kontakt-1. It is also equipped with the modern Shtora electro-optical system for defense against wire and laser guided anti-tank missiles. The new turret will provide protection against Kinetic Energy (RHAe) anti-tank guided missiles. Its new 9M119 Refleks is a laser beam riding guided anti-tank missile designed to penetrate 900 mm of RHA. Since this version has not entered serial production for Serbian army new more modern version M-84AS1 is developed that will enter serial production.
Apart from external differences to the M-84, it also has different internal structure and equipment, far surpassing the M-84AB in both capability and durability. Developed originally from the M-84, the M-84AS is more than just a quick tweak to bring it up to standard. Many improvements were adopted from what can be argued to be its sister tank, the T-90S. With slight differences in armour and maneuverability; the T-90S is better armored while the M-84AS is faster and more maneuverable. Considering the speed perspective, the M-84AS moves at 75 km/h on road while the T-90S moves at 60 km/h on road with off-road speeds varying according to terrain. The armor on the T-90S is somewhat superior with thicker composites, NBC protection as well as having the option of Active Protection System and KMT mine sweeping systems.Tank Т-90СT-80U and T-90 Trials 20.10.99 Aside from the propulsion and armor, the targeting system is equivalent.
