Over 85% of the components in rockets like Kalibr and other high accuracy cruise missiles are sourced outside Russia, much of it formerly coming from the West.

Over 85% of the components in rockets like Kalibr and other high accuracy cruise missiles are sourced outside Russia, much of it formerly coming from the West. While they may or may not have the money to pay for new missiles, Russia continues to have a difficult time replacing those losses. Russia had very large stockpiles of these missiles before the war, but they've chewed through them at a prodigious rate. From all estimates I've read, they are feeling the pinch, because their logistics are a mess on a good day and the sanctions make sustainment (particularly for high precision munitions) very challenging. Russian logistics were not designed for this type of long, drawn out campaign and it is showing on the battlefield.
