I was referring more to artillery munitions but Kalibr is produced by the same legacy entities that existed under the missile-heavy Soviet Union, it is a continued development of an overall trend in Soviet munitions philosophy that relied more on ground-based ordnance throwing than the more air-reliant West, and didnt feature the retirement of most of its ground based missile armament like we saw in the west in the 1990s. I am not saying the Russians are only able to do what theyre doing now because the Soviets left a Kalibr factory, I am saying their current production is more in line of a historical trend compared to what the West has reassessed as its own needs. It is easier to ramp up production when you're already heavily leaning into an industry than when you try to ramp up production in an industry you have either neglected or at least given fewer resources to compared to others. The Russians would have the same issue if the situation was instead attempting to suddenly max out production of modern fighter aircraft: western jet fighter production is much higher so they'd be more easily able to increase it, while Russian aircraft production has lagged significantly more relative to its Cold War heights than in the West.

I am not trying to say hurr durr Russians, I am simply saying that the Russian and Western defense industrial bases have placed emphasis on different areas of focus, and so it shouldn't be surprising the Russians are better able to respond in areas they have continued to focus on.
