Soviet era, when he was returned he drew up a battleship design in 1936 September that could fire all or almost all of her guns in any direction providing a ship with unprecedented arcs of fire for her 406mm and 180mm guns. At long range all primary and secondary guns could fire at both sides while directly forward or aft, 66% of main guns and 50-66% of the secondary guns.
Bot not just this which were revolutionary, the engines to power the ship would be as unique as well! 3 Gas turbines would provide the ship with an extraordinary speed of 61-65km/h together with the reduced mass the big and bulky boilers would take up (33-35knots) but Kostenko provided an alternative as a more conventional steam turbine power plant.
