Did the Soviet Navy take significant technical ideas from Italian warship design?
Short answerYes; one clear example is the use of the Italian Pugliese underwater-protection system in Soviet battleship designs.
NotesSoviet designers did draw heavily on Italian technical work during the interwar period. The Pugliese underwater-protection system is a clear example carried into Soviet battleship planning. The exchange does not claim that every Soviet feature came from Italy. It identifies one specific system through which foreign design knowledge entered an ambitious domestic capital-ship program.
