Russia's military industrial complex hollowed out decades ago.
Corruption rots out at any investment, and Russia has neither the skilled engineers, the machines, nor the machinists to pull of any mass mobilization of their economy.
They have some of the worst demographic columns of any major country in Europe, made worse by the millions that voted with their feet when the war started.
Russia will try to build up their industry, but that is not something that can be magicked up quickly.
Ukraine can't go bombing, but for some reason, Russian military/industrial buildings and facilities have been burning with rather startling frequency since early last year.

Poor safety probably contributed to a good number of these, given the pressure from the top to increase production. UKR may not need to do much.
BUT
Many many Ukrainians speak fluent Russian. Corruption means poor security, generally. I have zero doubt that more than a small number of these fires were done by the SBU, or sympathetic Russians.
Russia is still big, but it is a shadow of the USSR. I would lastly point out that UKR was where many of the old USSRs factories were located.
I think a lot of people overestimate the Moscovy empire here. It is a hollow giant. Dangerous, but not invincible.
