Head of the naval forces of the Red Army V.

Actually proposal of "Battleship B", appropriate to the tasks - no less 30 900 ton.
New tasks, November 26, 1936 - to 30 900 ton, 36 knots, decreased armour
Recommended variant - 32 870 ton, 230 mm belt, 125 mm deck, 300 000 hp, 35,5 knots

Jule 3, 1937, tasks - 36 800 ton, 35 knots
Such a ship was considered too large to fight enemy cruisers and too weak to fight enemy battleships.
A. Zukschwerdt, head observer, June 21, 1937 - "Battleship A" with 9 x 406 mm, "Battleship B" to fight enemy battleships with 9 x 356 mm and 30-32 knots, and heavy cruiser to fight enemy cruisers, with 12 x 254 - 280 mm guns, 34-35 knots, and 26 000 - 30 000 ton.
Project 64 task - to fight enemy 406 mm battleships - 3 x 3 x 356 mm, 6 x 2 x 152 mm, 4 x 2 x 100 mm, 8 x 4 x 37 mm, 406 mm shells and 500 kg bombs proof armour, 28-29 knots
Project 64 - to 53 000 ton, 385 mm belt, 40 + 20 + 150 mm decks, 29 knots, 201 000 hp, 8000 miles range
Project 64 was very close to a normal battleship, and there was no point in its construction.
