Where British battleship materials came from

Where did the materials used to build British battleships come from?

Most came from Britain, with some strategically important rare metals supplied by imperial sources such as South Africa and Canada.

A large share of the raw material for British battleships came from Britain itself, reflecting the country's extensive domestic industrial base. Imperial supply remained important for selected inputs rather than for every ton of steel. South Africa and Canada supplied some of the rare metals needed for specialized components. Home shipyards therefore drew on a wider resource network for particular materials.
