Their aircraft manufacturing isn’t any better. If you go to the USAF museum in Dayton, OH, they have an F-16 sitting next to a MiG 29. The quality of manufacturing and workmanship is starkly different. The MiG looks like crap sitting next to the F-16. In fact, the MiG they have on display looks like crap compared to a German Me 162 Komet that was also on display (and was built in 1944 while being carpet bombed)
#26 yes they may not be built as well but the Russians built many more aircraft and tanks then the Germans and overwhelmed them. Even if it cost 20 million Russians their lives.
I read a science fiction story way back about a war where a planet built great starships but the enemy built more ships that were not as good and easily defeated individually but they won in the end as they had more ships.
