What R U smoking? It was Moskito of late 1930s. Yes, it became obsolete by 1941, but what plane design of 1933 didn't?
If you want some Soviet designs mentioned here, Su-2 and Yak BB were pretty lousy for different reasons, and TB-3 outlived it's intended lifespan by at least 5 years.
I agree, the Soviets made plenty of bad aircraft without tarring the Tupolev designs, which generally were pretty decent aircraft for their day
The problem was that they kept building the damned thing. A good, perhaps even excellent aircraft in 1936, but they were still building it in mass in 1941.
What would you be saying if the United States build six THOUSAND B-10 (slower than the TB, but with almost double the bombload), B-18 (FOUR TIMES the bombload) or B-23 (same speed, 3.5 times the bombload)? That the planes were crap and were some of the worst aircraft of WW II ( especially compared to the far better B-25)? Same deal here.
