How would small-tube boilers in the Queen Elizabeth class alter the ships and their role in the First World War?
Short answerThey could create 28-knot-plus capital ships and give the Royal Navy a faster, more cohesive heavy wing during the Battle of Jutland.
NotesGreater boiler power could be used with the existing hull or paired with a finer length-to-beam ratio to produce a 28-knot-plus capital ship. At Jutland, the Fifth Battle Squadron could close the Run to the South more quickly. Fast battleships with the Grand Fleet might also reinforce the Third Battlecruiser Squadron and intensify later encounters with the German scouting force.
