Small-tube boilers as a fleet-wide advantage

Small-tube boilers could have made British capital ships faster, but the benefit would ripple through fleet doctrine and foreign responses.

Question

What if the Queen Elizabeth and R classes had received small-tube boilers?

Short answer

They could have gained useful speed, giving the Royal Navy a fleet-level advantage that other powers would need to answer.

Notes

Better boilers could produce faster Queen Elizabeths and potentially faster R-class ships rather than changing one vessel in isolation. Queen Elizabeths might approach 28 knots and R-class ships roughly 25 knots. Existing high-quality turbines could accept the extra pressure, though faster wear would be a cost. Britain would enter the 1920s with a battle line whose speed changed its operational reach and concentration choices. Other navies would then have to answer a fleet-wide advantage rather than one unusually fast ship.
