U. S. Navy lieutenanr Matt Howland Signor published in the The Proceedings dated March 1902 his vision of a battleship. Displacement with all ammunition, stores and water and 1,000 tons coal was 15,975 ton and a draught of 26.5 feet and with 2,500 ton coal 17,475 ton and a draught of 28.5 feet. The dimensions were 400 x 80 x 17-15-16 (armored freeboard fore-amidships-aft) feet. Endurance with a speed of 16 knots was 3,000 nautical miles, with 18,000hp able to maintain during 4 hours a speed of 18 knots and with 11,500 hp a sea speed of 16 knots.
Normal displacement 15,975 tons:
Hull steel, 4,000 tons
Armor decks, main and protective 1,600 tons
Hull, wood 140 tons
Hull fittings 720 tons
Outfit, masts, ladders, furniture 100 tons
Equipment 125 tons
Electrical 15tons
Boats 25 tons
Officers, men and effects 110 tons
Stores 200 tons
Fresh water fordrinking 50 tons

The armament was to consist of 2x3-33,02cm/13”cal 40 guns (fore and aft), 2x3-25,4cm/10” cal 40 guns (beam amidships), 12-12,7cm/5” 60 cal guns and 16-7,63cm/3” cal 50 guns, totally 40 guns. An option was to replace the 12-5” guns by 18-10,16cm/4” cal 60 guns. Signor wrote that 3-10” guns in a beam turret was preferable above a 2-12” gun turret. The problem was to solve as 4x3-12” gun turrets or 2 turrets with 13” and the others with 10 guns. He maintained his opinion that the battery should be 6-13” and 6-10” guns.
The original article supplies much more details including dealing with the proposed armor.
