An item referred to the magazine Scientific American which reported that at least at two large shipyards along the Clyde two super dreadnoughts, sister ships, with about the same length of the proposed American battle cruiser (a length of 850 foot) and an main armament of 10/12-40cm (or even heavier) guns and the heaviest armour were designed and built in around 18 months. Both ships had two shifts each working 10 hours with 4 hours quietness between.
