Oil firing and an alternate fast-battleship fleet

Did turbines and oil fuel together define the dreadnought, and what if Queen Elizabeth had achieved 28 knots?

Turbines were decisive for Dreadnought, while oil firing arrived later; a 28-knot Queen Elizabeth generation could have created a large fast battle line and altered Hood, treaty bargaining, and interwar fleet balance.

Dreadnought's turbine revolution preceded the Royal Navy's adoption of oil firing. If Queen Elizabeth had combined oil, small-tube boilers, and 28 knots, the Revenge and Admiral classes might have evolved as fast battleships rather than splitting into slow battleships and extreme-speed battlecruisers. Nelson and Rodney might also have been designed around the faster fleet standard. Britain could then have retained roughly eighteen capital ships capable of at least 28 knots, with refits focused on preserving that speed. An American 21-knot battle line would have faced a markedly different parity problem during treaty negotiations.
