Queen Elizabeth design question

The central question is whether the Royal Navy made the right choices with the Queen Elizabeth class. The ships entered a worldwide dreadnought field that already included American, French, Italian, Japanese, and Australian construction. Their designer associated about 900 tons of avoidable weight with the change from an original coal-burning arrangement to oil fuel, a redesign that affected machinery layout, draft, speed, and space for armament. A later estimate suggests that a cleaner oil-fired design might have saved about 1,200 tons for more armor or propulsion. The class therefore needs an integrated judgment across all these features.
