You miss my point. Biplanes weren’t a backbone of Soviet air force during WWII for sure, thus they had a SMALL number of biplane fighters (i-153). These planes were a rollback from an i-16 known as a rata or mosca. An i-16 was a pretty revolutionary plane for earlier 1930s (a fast agile monoplane featuring retractable landing gear). An i-153 biplane came in 1934 as a less revolutionary alternative but the history proved that even an i-16 turned absolete by late 1930s with a Bf-109 in the skies.
The point is the Soviets has stuck with a technology from the early 1930s with Stalin’s purges.
U-2 biplane in Night Witches’ use weren’t even a combat planes.
Agreed—and nothing against biplanes, either. As I stated, Russian designs have always impressed me.
