Could the Soviet economy realistically support twelve new battleships?
Short answerNot all at once or by 1936, but Stalin could force a slower multi-yard program whose treaty authorization would still shape every rival navy's planning.
NotesTwelve Soviet battleships by 1936 are implausible. Treaty authorization would instead create a long-term program spread across the yards capable of handling the hulls. Engineering capacity and construction time would limit simultaneous work. Stalin's willingness to impose enormous human and economic costs could still drive the program faster than a democratic cost model would suggest.
