What happens to fleet composition if the oil crisis continues into the 1920s?
Short answerOil-secure powers expand storage and overseas access, while navies unable to guarantee supply retain coal-fired ships for longer.
NotesA continuing oil shortage would encourage Britain to invest in more storage and pursue overseas access more aggressively. Countries able to secure oil would concentrate on doing so, while those without reliable access would retain coal-powered ships. The timing matters because most ships in the 1910s still used coal, sometimes supplemented by oil. The discussion identifies the Queen Elizabeth class as the point at which wholly oil-powered British capital ships enter this comparison. By that stage Britain had already worked to secure substantial access to oil.
