LOL. Ukrainian arms industry is defunct for 9 years after it lost paying customers. Now the remnants are partially destroyed on top of that.
Until recently, much of Russia’s arms exports relied on Ukraine’s participation and assistance in production. In effect, Ukraine became a subcontractor to Russia’s arms industry. Of course, that relationship is done, and Russia’s arms sales are now in collapse due to sanctions, the lack of manufacturing capacity, and the weak performance of Russian weapons in the attack on Ukraine. India, Russia’s largest arms purchaser, is now buying elsewhere and looking to manufacture domestically.
