RADICAL changes in dreadnaught design are coming out of the war tests between battleship and bomber, chief among them the streamlining of decks and turrets, not for aerodynamic reasons but to fend off aerial bombs, and the multiplication of anti-aircraft batteries. Otto Kuhler, American designer, suggests the whale-back battleship at the bottom of this page, its foredeck roofed with heavy armor plate, quantities of anti-aircraft guns over the enclosed bridge and streamlined aft turret, below which is a hangar housing bombers, fighters and reconnaissance planes launched by catapult. The larger drawing is that of an English designer, showing similar arched superstructure designed to let bombs and shells ricochet off with minimum damage. This battleship would have exhaust outlets at the stern, displacing the conventional funnel, and its 70,000 tons would call for turbines of 252,000 horsepower driving six propellers. Armament includes eighteen 14-inch guns, twenty-four 5.25-inch guns, sixteen 4.7-inch anti-aircraft guns and seven multiple pompoms.
