Russia Confirms Bringing New Tank Variant Into Frontline Service: How Capable is the T-72B3A?

Russian media outlets have confirmed the service entry of a new type of main battle tank, the T-72B3A, with military units operating in the Ukrainian theatre confirmed to have already received the vehicles. The armoured vehicles and crews are currently being actively trained for combat use, with local media reporting that their new capabilities will be “required to support our assault groups attacking enemy fortified areas.” Before being sent to the front lines, crews undergo additional training, specifically to familiarise themselves with the tank’s Arena-M active protection system, which is the primary new addition distinguishing the tanks from prior T-72 variants. It is notable that the Arena-M has been seen on frontline T-72s since late 2024, raising questions whether these were also T-72B3A tanks, or whether there are other features distinguishing tanks with this designation. 

Russian sources have particularly highlighted that the new active protection system is capable of protecting armoured vehicles not only from projectiles and anti-tank missiles, but also from loitering munitions and first-person view drones, which have emerged as a leading threat to tanks on both sides of the conflict. Commenting on the importance of the Arena-M’s integration, defence expert Yuri Lyamin was cited by Russian media outlets observing: “It's important that tanks equipped with active protection systems are being deployed to units performing combat missions, rather than being displayed at exhibitions or parades… Currently, small tactical drones pose the main threat to armoured vehicles. Being able to effectively counter them will save not only the vehicles themselves, but also the lives of their crews.”

The Arena-M uses a multifunctional Doppler radar to continuously monitor the surrounding environment for incoming threats, and when detecting an incoming projectile tracks it automatically, calculates its trajectory, and deploys protective munitions to intercept and destroy it before it impacts the tank. Twelve launchers are integrated around the tank’s turret. It was confirmed in early January that a new variant of the Arena-M system capable of intercepting single use drone and loitering munition attacks had completed development, raising the possibility that the T-72B3A could be the specific variant that has integrated this new enhanced version of the system. The baseline Arena-M can intercept rockets, missiles, and anti-tank projectiles travelling as fast as 1,000 meters per second at ranges of up to 50 meters, with the capabilities of the new improved variant remaining unknown. 

Commenting on the capabilities of the new T-72 variant, Russian defence expert Dmitry Kornev observed: "Essentially, the tank is receiving its own air defence and missile defence system.” He stressed that the system’s ability to shoot down drones was its most important feature, noting that all-aspect protection could significantly change the role of armoured vehicles in modern combat and once again enhance their importance in ground operations. Preceding the T-72B3A’s unveiling, the Russian state defence conglomerate Rostec in early March stated that the T-72 had very significant potential for further modernisation. 

Approximately 200 modifications have been made to the T-72’s design since the outbreak of hostilities, which have improved  its firepower, protection levels, and mobility. Nevertheless, the T-72’s role at the centre of the Russian tank fleet has diminished considerably, with the proportion of the fleet formed, by T-62, T-80 and T-90 tanks having increased significantly, while the rapid expansion of T-90M production is expected to relegate the T-72 fleet to a more minor role. The T-72B3A builds on the T-72B3 upgrade package developed in the early 2010s, with integrates modern fire controls including thermal sights, as well as Relikt explosive reactive armour and a new 2A46M-5 smoothbore gun on to the tanks.
