Russia's T-90 Is Dangerous Weapon. Could It Beat America's Best Tank in Battle?

While the T-14 Armata might be Russia’s latest and greatest tank, it still is not ready for service. In order to bolster the capabilities of their more conventional tank fleet while the Armata is being prepared, Russia continues to modernize its current “top-tier” tanks, such as the T-90. Recently forty T-90Ms, the latest variant of the T-90, were reported to be ready for delivery in the near future to combat units. Similar to the M1A2 SEP v3, this is an upgrade kit that builds upon and improves the capabilities of the tank. It is unknown at this time whether the T-90Ms being delivered are kits being retrofitted to T-90s or T-90As. But how do these two souped-up tanks compare?

Unlike earlier generations of Russian tanks, the T-90M has practically every feature that modern Western tanks enjoy. While earlier tanks sometimes lacked an independent commander thermal sight, instead only having independent commander day/night sights, the T-90M mounts the PK-PAN independent commander sight. The gunner’s sight is also thermal, the now-standard Sosna-U module. Both of these sights appear to still use the French Catherine thermal matrices, there is no indication that the Russian Irbis-K thermal modules have been implemented in the T-90M as it will be procured. These two sights are linked, with the tank’s information-management system able to pass a target designated by the commander directly to the gunner. Russian sources state that this is the first time such a feature has been implemented on a domestic tank. However, this has been a standard feature of Western tanks for some time.

The Kontakt-5 explosive-reactive armor on earlier T-90s is replaced by the more effective Relikt. Some kind of net or chain armor appears to be deployed under the turret Relikt packages to decrease the effectiveness of HEAT shots to that area. While earlier photos of the T-90M showed slat armor in this area, photos from late 2017 and early 2018 show net armor here. Slat armor is also added to the rear of the tank to decrease the chances of a mobility kill. Fourth-generation Malachit ERA could later be fitted to the T-90M, but there are no pictures of T-90Ms with Malachit, and the first T-90Ms will likely be delivered without it. The gun’s accuracy is also improved, but it remains a variant of the 2A46 cannon. The commander’s 12.7-millimeter machine-gun system also appears to be a new design, mounted high up above the commander’s thermal sight. This is taller than earlier T-90s, and probably provides increased functionality similar to the American CROWS systems.

The laser detection and presumably smoke deployment modules of the Shtora active protection system are retained, however, the active jamming “eyes” are removed. It’s speculated that the reason for this is Shtora’s ineffective nature against modern ATGMs. It is speculated that the Armata’s Afghanit APS could be later fitted to the T-90M later on, but there are no current pictures or evidence that Afghanit is being implemented on the T-90M. The T-90M also appears to feature increased creature comforts, including air-conditioning units. The driver’s station is also modernized, changing from the harder-to-learn and -use levers of earlier Russian tanks into a yoke-type similar to that used on the M1A2 Abrams. It also features a diagnostic/logistic management system and improved radios.

The M1A2 SEP v3 includes many of the same upgrades as the T-90M: an unknown hull and turret armor upgrade, improved (third-generation) thermal imagers for the commander and gunner’s sights, and a revised CROWS system. Interestingly enough, the new CROWS for the SEP v3 is revised to be lower profile, whereas on the T-90M the profile of the remote weapon station is increased. While the actual cannon remains unchanged on the M1A2 SEP v3, an ammunition datalink is added that allowed to use new HE MPAT rounds. The M829A4 APFSDS round is also included with the SEP v3 update, giving increased capability. It also includes the Trophy active-protection system. Like the T-90M, improved radios and logistical systems are part of the update.
