Russia has a massive industrial capacity, with no environmental restrictions. And they can get stuff from China, Iran, and elsewhere. Some Russian used Chinese weapons have been captured/destroyed by Ukraine.
NATO and the West are able and willing to provide more and better gear. As long as the west keeps backing Ukraine, Russia is going to lose the war of attrition, if the increasingly better trained and equipped Ukrainians don’t beat them on the battlefield with a succession of tactical victories changing the overall strategic situation as they have been doing first.
‘ Russia has a massive industrial capacity”
Did you not read the article or are you saying you don’t believe what was written?
Russia on the other hand, has a very limited industrial capacity and millions of its best engineers and leaders have fled, while hundreds of thousands of grunt workers are being fed to the Ukraine meat grinder.
When was the last time you or someone you know purchased a Russian made vehicle?
No, it doesn't.
The trick here is to look and see how much truly new stuff the Russians had when this war first began, because the amount of new stuff gives you an idea of how much they are able to produce. And the answer is pretty pathetic. The mainstay tank of the Russian army at the outset of the war was the T-72, which is basically a somewhat simplified version of the T-64. And the T-64 first entered service in 1959.
They later created a gas turbine variant of the T-72, called the T-80. That's their best MBT, but they produced the last of those way back in 2001. Good tank, but difficult to maintain and the gas turbine engine is a massive gas hog, which creates logistical issues. They subsequently produced the a few hundred T-90's, but that's an inferior tank even to the T-80 and they stopped production. They worked on a more modern tank that was supposed to be able to compete with the U.S. M-1A1, that was dubbed the T-14 Armata. In 2015, they placed orders and were supposed to have 2,300 T-14's fielded by 2020.
They can't get the program off the ground, and have produced a couple dozen at most. The program is a failure.
Corruption has killed their weapons industry, as well as the logistics and maintenance support. They'd first have to build a weapons industry, then build the equipment. That's a multi-year project given the demands of modern technology.
