#125mm
Few people know it, fewer people adore it. It is the VDV's vehicle of choice should they need MBT equivalent firepower in a nimble and speedy package, it also is amphibious! It is bound to be a headache for any unlucky foe that crosses path with its powerful cannon, but don’t be fooled! It can be just as easily destroyed.
In War Thunder, the T-80s are among the pinnacle of Russian MBTs. They are fast, have a good gun, and decent armour. They excel at many roles, and at all ranges. The T-80U-E1 is a modification of the existing T-80U, with better thermals and a slightly better turret traverse. This variant is technologically superior to most other T-80s apart from the T-80BVM. How is this vehicle played?
Emerging from the T‑72 lineage, the T‑90A refines Cold War resilience with early‑2000s tech upgrades. Outfitted with Kontakt‑5 ERA and a composite armor suite, it maintains a low silhouette while boasting a robust defensive profile against both kinetic and chemical rounds. At its core sits the 125 mm 2A46M‑5 cannon autoloaded and stabilized, capable of launching a wide range of ammunition, from standard APFSDS to tandem‑warhead ATGMs. Its most distinct feature, however, is the Shtora-1 electro‑optical protection system — it's an "unblinking hunter", thanks to its ever-watchful "eyes".
Emerging from the T‑72/T‑90 lineage, the T‑90M “Proryv” blends proven Soviet design with targeted modernizations. Relikt ERA and composite modules reinforce its low‑profile turret and sloped glacis, reducing incoming damage. At its heart sits the 125 mm 2A46M‑5 cannon with an autoloader, capable of launching APFSDS, HEATFS, HE, or tandem‑warhead ATGMs offering adaptable firepower at all ranges. Though its –6° gun depression and 4 km/h reverse speed limit certain hull‑down and withdrawal maneuvers, the T‑90M excels when used to dictate engagements from hull‑down positions, supporting advances and punishing overextended foes.
