Would the Queen Elizabeth class gain triple turrets or small-tube boilers in this scenario?
Short answerSmall-tube boilers are judged more likely, potentially with five twin turrets and a speed of about 25-26 knots.
NotesThe proposed Queen Elizabeth alternatives include triple turrets or small-tube boilers. The expectation favours boilers because the Royal Navy had already tested progressively smaller-tube machinery elsewhere. Triple heavy-gun turrets lacked the same history of British service experience at this point. The comparison with later triple 4-inch mounts illustrates the preference for trying an arrangement on a smaller scale first. Retaining five twin turrets would give ten guns, with an estimated 25-26 knots despite an initial aim of 28. The boiler improvement is also qualified as period machinery, rather than the more developed equipment of much later ships.
