Russia doesn’t have now enough tradesmen, skilled technicians, engineers, nor the hundreds if not thousands of small, high quality contractors. It’s taking them a decade from laying the keel to launching a hull. Even longer.
They have the skills not the money. What workers they don't have can be imported. BTW I look for Russia to go back to the Old Ways soon. If China and Russia decided to start turning out even older Diesel powered subs we would be in a world of hurt because SOMEBODY discontinued such valuable programs as the S-3 Vikings as well. A certain Congressional majority allowed it to continue on into the 2000's until booted from power.
Only one carrier was ever built with a sonar dome and the Navy sank it. Even that carrier relied heavilly on S-3 and helo's for antisubmarine warfare. Underestimating China and Russia military capabilities and determination will be a very bad and possibly fatal mistake for our national survival. One lucky hit into NORVA and that's it.
