IAR figures show, that since the start of the war, Russia’s seven main tank repair and maintenance facilities have delivered 180-360 tanks of all types to the field. Western sanctions have effectively ended Russian capabilities to produce new tanks of any type and is currently used, without exception, to refurbish old Soviet armor.

Hmm. That wasn’t Perun’s take. His argument was that new tank production continued, albeit not at a level sufficient to fill losses. He based that on the bifurcation in level of recorded losses: there is an increasing amount of older tanks being lost, a roughly constant amount of newer tanks being lost, and a decreasing amount of tanks in the middle. His interepretation was that this was the result of out-of-production “middle” tanks being exhausted and Russia needing to dig into ever-older stores to make that up, with production if new tanks continuing but not at a level sufficient to sustain losses.

EDIT: Hmm. This also talks about production.

“The Russian defense industry is still capable of producing tanks but at an insufficient rate to make up for the losses [and] a successful Ukrainian offensive would be catastrophic for the operational tank fleet,” the IAR report said.
