Russia’s production of its most advanced tank, the T-90M “Breakthrough,” has fallen off dramatically in 2025, casting serious doubt on claims of a manufacturing surge. After upgrading its existing fleet of older T-90As, the main tank factory, UralVagonZavod, has struggled to produce new builds. This production crisis is compounded by reports of poor quality, including bad welds, and deep-seated company issues like lawsuits for unpaid bills, low wages, and corruption.
