 The first Tactical @-@ Technical <unk> ( abbreviated in Russian as TTZ ) for the large battleship design was issued on 21 February 1936 but proved too ambitious , <unk> nine 460 mm guns and a speed of 36 knots ( 67 km / h ; 41 mph ) on a displacement of 55 @,@ 000 tons . The TTZ was revised in May 1936 by Admiral Orlov , Commander of the Soviet Navy , reducing speed to 30 knots ( 56 km / h ; 35 mph ) , and weakening the secondary and anti @-@ aircraft batteries . A few months later Admiral Orlov further reduced the size of the battleship to 45 @,@ 000 tons and set the size of the main guns at 406 mm . Shortly afterward , the Soviet Union signed the Anglo @-@ Soviet <unk> Naval Agreement of 1937 and agreed to follow the terms of the Second London Naval Treaty that limited battleships to a displacement of 35 @,@ 560 metric tons ( 35 @,@ 000 long tons ) , although they did add a <unk> that allowed them to build ships of unlimited size to face the Imperial Japanese Navy if they notified the British . Yet another TTZ was approved by Orlov on 3 August for ships of 41 @,@ 500 tons with an armament of nine 406 @-@ millimeter , twelve 152 @-@ millimeter ( 6 @.@ 0 in ) , twelve 100 @-@ millimeter ( 3 @.@ 9 in ) , and forty 37 @-@ millimeter ( 1 @.@ 5 in ) guns , a maximum armor thickness of 380 mm ( 15 in ) and a speed of 30 knots .
