As mentioned though, Russia would never allow their defense industries to just fall apart in such a manor. As much as I am against the integration of buying foreign equipment (If you do not learn from History, then history tends to repeat itself. In the sense of buying stuff that can later be used against you), it is good that they are attempting to make it in their own facilities (but in the end, funding mainly France's industries).
But if they allowed internal competition, then it would force development in Russia for higher technologies. Instead, everything is state run, which is not helping a lot in the R&D sectors.
