A pair of designs were prepared in June 1920, derived from the "U-4" battleship design of 1914, of ships with displacements of about and armed with eight or nine guns, in four twin or three triple gun turrets mounting a new gun then under development. The only limitation of the design was the inability to use British dockyards and pass through the Suez Canal. The most unusual feature of these designs was that none of the turrets were superfiring, presumably to keep the centre of gravity as low as possibleBrown, pp. 172–173 and avoid the extra weight required for tall, superfiring barbettes.Campbell, Part 2, p. 13
