Uralvagonzavod: T-90M Production, Tank Refurbishment and the Soviet-Stock Drawdown
Uralvagonzavod — UVZ — is the single most important plant for Russia's armoured forces and the bottleneck that determines how fast Moscow can replace the thousands of tanks lost in Ukraine. Based in Nizhny Tagil and part of Rostec, it builds new T-90M main battle tanks and, more importantly by volume, overhauls T-72 and T-80 hulls pulled from vast Soviet-era storage parks. As the most restorable of those hulls run down, the sustainability of Russia's tank fleet hinges on this factory. Russia publishes no audited output data, so figures here are framed qualitatively.
What UVZ Is
Uralvagonzavod is Russia's main battle-tank manufacturer, historically also a railcar producer, located in Nizhny Tagil in the Urals. It is part of the Rostec state conglomerate and is the only plant capable of series-producing the modern T-90M «Proryv» (Breakthrough). Alongside new builds, it runs the large-scale modernisation lines that return stored T-72 and T-80 tanks to front-line service.
For Ukraine, UVZ matters because Russian armoured losses have been enormous, and the plant’s combined output is the principal source of replacements. Its capacity, and the dwindling pool of restorable hulls it draws on, sit at the centre of any honest assessment of how long Russia can keep fielding mass armoured formations.
New Builds vs Refurbishment
The headline «tank production» figures attributed to Russia mostly describe refurbishment, not new manufacture. External estimates suggest total tank deliveries climbed from roughly 90–110 a year before the war to around 250–300 in 2024 — an effective tripling — but the large majority were modernised T-72B3s and T-80s rather than new tanks. New T-90M output is far smaller, with estimates clustering in the range of 60–90 a year.
That split matters. Refurbishing a stored hull is cheaper and faster than building from scratch, but it depends on the supply of usable hulls. A genuinely new T-90M requires modern fire-control systems, thermal sights and precision-machined parts that sanctions make harder to source. The result is a fleet increasingly composed of older designs with upgraded protection and optics, rather than a wave of new top-line tanks.
The Soviet-Stock Drawdown
Russia entered the war with thousands of tanks in long-term storage, and that reserve has underwritten its replacement rate. But the easiest-to-restore vehicles are used first. The IISS and other analysts have tracked a steady decline in stored numbers; in one window in 2025, Russia's overall stored tank reserve was assessed to have fallen from around 3,100 to roughly 2,500, with the best-condition T-72A stocks dropping sharply.
The remaining hulls tend to be in worse condition, demanding more labour and parts per vehicle. That implies the high refurbishment rates of 2023–2024 are unlikely to hold indefinitely. The crucial uncertainty is timing: when the restorable stock thins enough that UVZ’s effective output falls back toward its much smaller new-build capacity. That inflection, more than any single annual figure, is what analysts are watching.
Sanctions and Machine Tools
Sanctions on UVZ aim at the precision machine tools, optics and electronics that modern tanks require. Reporting has documented the plant using European-made CNC machinery acquired through sanctions-evasion networks, and modern thermal imagers and fire-control electronics remain a recurring choke point. As with Russia’s missile makers, enforcement gaps let dual-use equipment trickle in via third countries.
The net effect is uneven. Sanctions slow the pace and degrade the quality of genuinely new builds more than they stop the refurbishment of simpler older designs, which rely less on cutting-edge imports. UVZ is designated by the US, EU, UK and partners, and as a Rostec subsidiary it is one of the most prominent sanctioned Russian defense firms.
Workforce and Constraints
Public data has put the Nizhny Tagil workforce at roughly 12,000 employees, working extended shifts to sustain wartime output. Labour availability, skilled-worker retention and the supply of imported machine tools are recurring limits on how fast production can grow — arguably as binding as raw material constraints.
Taken together, the picture is of a plant running hard but bumping against structural ceilings: a finite stock of restorable hulls, sanctioned tooling for new builds, and a labour pool stretched by competing wartime demands. UVZ can keep replacing losses for now, but the trend lines point toward tightening, not expanding, capacity over time.

Frequently Asked Questions
What is Uralvagonzavod?
Uralvagonzavod (UVZ) is Russia's main battle-tank manufacturer, based in Nizhny Tagil and part of the Rostec conglomerate. It builds new T-90M tanks and overhauls older T-72 and T-80 hulls drawn from storage. It is the single most important plant for Russia's armoured forces and a heavily sanctioned entity.
Does Uralvagonzavod build new tanks or refurbish old ones?
Both, but refurbishment dominates the numbers. Most of the tanks reaching Russian units are modernised T-72B3s and T-80s pulled from Soviet-era storage, with a smaller stream of genuinely new T-90M builds. The balance is heavily weighted toward refurbishment because new-build capacity is limited.
How many tanks does Uralvagonzavod produce per year?
External estimates suggest total tank deliveries rose from roughly 90-110 a year before the war to around 250-300 in 2024, counting both new builds and refurbishments. New T-90M output is far smaller, with estimates in the range of 60-90 a year. These figures are approximate and drawn from open-source analysts, not official data.
Is Russia running out of Soviet-era tanks to refurbish?
The most easily restorable hulls are being used up. Analysts including the IISS have tracked a steady drawdown of stored vehicles, with the best-condition tanks depleted first and the remainder needing more work. This suggests the high refurbishment rate of 2023-2024 may not be sustainable indefinitely.
How do sanctions affect Uralvagonzavod?
Sanctions target the precision machine tools, optics and electronics needed for modern tanks. Reporting has found UVZ using European CNC machinery obtained through evasion networks, and modern fire-control and thermal sights remain a choke point. Sanctions slow new-build quality and pace more than they halt refurbishment of older designs.
Has T-90M production fallen in 2025?
Some 2025 reporting suggested new T-90M deliveries dropped sharply, with very few confirmed new-build batches early in the year. The picture is contested and based on limited visual evidence, so it should be read as a signal of strain rather than a precise figure. Refurbishment of older tanks continued in parallel.
Is Uralvagonzavod under Western sanctions?
Yes. UVZ is designated by the United States, the European Union, the United Kingdom and other partners, with asset freezes and export controls aimed at its supply of dual-use machinery and components. As a Rostec subsidiary it is one of the most prominent sanctioned Russian defense firms.
How large is Uralvagonzavod's workforce?
Public data has put the Nizhny Tagil workforce at roughly 12,000 employees, working extended shifts during the war. Labour availability and skilled-worker retention are recurring constraints on how fast output can rise, alongside machine-tool and component bottlenecks.
Why does Uralvagonzavod matter to the war?
UVZ is the bottleneck for replacing Russia's massive tank losses in Ukraine. Whether Russia can keep fielding armoured formations depends on the plant's combined new-build and refurbishment output and on how long the stock of restorable Soviet hulls lasts, which is why analysts watch it closely.
Where can I find reliable analysis on Uralvagonzavod?
Credible open sources include the IISS, SIPRI, RUSI, the Oryx loss tracker, ISW and Reuters, plus Ukrainian defense-intelligence releases reported via Defense Express. This page is analysis, not investment advice, and figures are framed qualitatively given the opacity of Russian data.
