Well their scientific output (not only for military applications) was actually very high, but they already had a great scientific community before Communism.

If they didn't then they wouldn't have been able to keep up for such a long time and Russia today couldn't be such a big geopolitical adversary to this day.

If they had not implemented Communism after WWI I believe they could have been a second US.
