Reverse engineering was the only option to make long range bomber fast enough after WW2. Pre-war bombers were obsolete and a proper Soviet made jet bomber was only designed by 1950-s. I read Tu-4 had worse characteristics comparing to Superfortress because of differences between metric and imperial systems. Metal thickness didn't translate well to millimeters and Soviet plane was slightly heavier. It had different engines too.
There was a story that Soviet constructors copied even a can holder in cockpit, but that's probably an urban legend.
I read they copied a drill holes that was a mistake.
Apparently they reverse engineered some if the trucks as well early GAZ series had a few designs borrowed from the USA. Trucks that later got used on the HoChi Min trail
The English also over rated how good German jet technology was and sold a jet engine to the USSR assuming they already captured better engines from the Germans.
Apparently Stalin almost fell over in shock.
Germans built the world first Jet fighter but the British invented the Jet engine. British had the best plane engines in WW2. The Soviets cloned that 1944 engine and put it in the MiG 15.
The MiG 15 gave a decent account of itself in Korea. Oops.
Our country might be able to engineer a good cheese or wine on a good day, it's funny reading about designs from other nations.
