Vietnam's T-90S tank is as strong as the T-90MS

Both are export versions of the T-90 tank, so the T-90S Russia exported to Vietnam possesses power and technology that is not inferior to the T-90MS version.

Demonstrate strength

According to the introduction of Uralvagonzavod Group, the T-90S version is equipped with advanced technology, better than the Russian T-90A version and not inferior to the T-90MS version. The hull and turret of the T-90S are armored with 3 solutions: multi-layer composite armor, rolled armor and plate armor.

The body is made by welding in a box shape, the nose is wedge-shaped with layers of steel welded at a 68-degree angle. The side of the car is vertical, the rear armor has a reverse slope. The upper part of the body is rolled steel plates pressed together. The bottom steel plate of the car is a stamped steel plate, with a relatively complex structure.

The T-90 turret is a cast or welded plate turret (T-90S, T-90MS and T-90A) suitable for the ASUO 1A45T fire control system. The turret armor is two wedge-shaped layers with an angle of inclination of 55 degrees along the longitudinal axis of the gun barrel, in this combined armor layer there are semi-active armor components.

Steel armor is also reinforced by using double-layer explosive reactive armor. Combined with explosive reactive armor, the nose and body of the vehicle can withstand armor-piercing bullets from 1150 - 1350 mm. The vehicle's sides are fitted with synthetic rubber shields.

T-90S tank.

The sides of the vehicle are equipped with 3 steel plates with explosive reactive armor on each side. The explosive reactive armor is Contact-5 type, on the front armor plate there are 12 armor blocks, on the front turret and on the face there are 8 explosive reactive armor blocks, on the side shields there are 6 shields.

The vehicle's drive system is a suspension type, with independent torsion shafts, with six load-bearing wheels on each side of the vehicle, and hydraulic shock absorbers are installed on the first, second and sixth load-bearing wheels.

The 750mm diameter heavy-duty wheels are covered with abrasion-resistant synthetic rubber, and the wheel frame is made of aluminum. The T-90S is equipped with an engine with a capacity of 1,000 horsepower - equivalent to the power of the T-90MS.

Muscle strength

The T-90S version exported to Vietnam is equipped with a 125 mm smoothbore gun - anti-tank missile launcher fired through the 2A46M-4 gun barrel. Sight angle -6…+13.5 degrees. Rate of fire: - 7 rounds/minute (automatic reload).

Firing range: 4000 m (Sub-caliber armor-piercing shells); 5000 m (PTUR anti-tank missiles); 10,000 m (High-explosive fragmentation shells). The artillery ammunition load is 42 shells, of which 22 shells are in the autoloader cassette, 20 shells are in the ammunition compartment in the hull and turret.

The T-90S is equipped with ammunition including: 3UBK20 anti-tank ammunition using 9M119 anti-tank missiles, 3VBM17 tungsten-core anti-tank ammunition, armor-piercing capability with a 60-degree angle of impact of 600m with a range of 2000m; 3VBK25 multi-purpose hollow-point ammunition; 3VOF36 high-explosive fragmentation artillery ammunition and other types of ammunition.

Anti-tank missile fired through the 9K119 Refleks gun barrel. Control: semi-active by laser. Laser irradiation system is used by laser rangefinder 1G46 target designator (equivalent equipment on T-90MS). Penetration ability with 60 degree impact angle with homogeneous armor, penetration after explosive reactive armor is 350mm.

The 12.7 mm HSVT Utes anti-aircraft machine gun on the turret is controlled by the 1ES29 remote control device with range and direction stabilization system, control drive system. Effective range up to 1600m and capable of attacking air targets with flight speed from 100 - 300 m/s.

In addition, the turret is also equipped with a 7.62mm PKT or PKMT co-axial machine gun, an 81mm PU smoke generation system type 902B Tutra on the 12-barreled tank gun. Although the T-90S version does not have the Shtora 1 system like the T-90MS, in return, the vehicle is equipped with the extremely modern Arena system.

To enhance combat effectiveness and vehicle safety, the Russian T-90S sold to Vietnam is also equipped with TIUS information management and control equipment, which collects information, processes information and simulates real-time information about the battlefield situation, the situation of tanks in the squad (up to the brigade), the technical status of the vehicle body, weapons and equipment, etc.

Automatic fire control system 1A45T IRTRUS. The control system includes: ASUO 1A42 - technical computer for daytime aiming device 1A43; laser aiming and measuring device 1G46 with magnification from 2.7x to 12x; laser measuring device from 400m to 5000m;

missile control system (laser irradiation); 1V528-1 ballistic trajectory computer; DVE-BC firing condition sensor complex; 2E42-4 Zasmin weapon aiming stabilization system; TO1-PO2T (Agava-2) thermal imaging night sight.

The PNK-4C commander's sight and observation system allows the commander to control the fire of the anti-aircraft machine gun, and can also be used in the mode of replacing the gunner to fire the main weapon of the vehicle. Communication station: R-163-50U Arbalet -50U uses the UKV frequency band and the R-163-UP - T-90 receiver.

As the main attack tank of the Russian army, the T-90 has strong firepower advantages, most combat operations are automated, and the vehicle is highly mobile on all complex terrains, including Vietnam's terrain.
