There was just two forms of defence agansit a submarine attacking a target with her torpedoes. One was to destroy the submarine herself or improve the protection of the target, especially the bottom of the surface ship. In his article described Biles (1) some designs of battleships which should be able to keep fighting even after being torpedoed by a 21” torpedo. One of the solutions was to armor the bottom resulting in reducing her speed with 2 knots. The newest battleships had a form with a low resitance to forward motion. His idea was to develop a form better adapted to fitting and carrying armor despiter creating greater resistance or a reducing speed.
One design he suggested was without a reduced speed, upper armor and armament but able to fight next other dreadnoughts in the First or Second Battle Squadron and which was armored against torpedoes. Displacement 28,500 tons and as dimensions 570 (between perpendiculars)-600 (over all) x 91 (extreme) x 28.6. feet. Speed 21 knots. Armament 10-14” guns and 16-6” guns. Armour consisted on side at waterline 10”, above waterline 7 and 5”, below waterline 4”, on casemate 2”, on barbettes 12” and with 3” thick protected deck-plating.
