Early steels were costly and resisted corrosion poorly, but bulk production in the 1870s made stronger hulls economical without demanding a wholesale change in yard machinery or working practice. By 1890 British yards could build lighter ships with more cargo or fuel capacity, and output peaked dramatically before the First World War. In 1913, yards across Great Britain and Ireland launched 1,460 ships totaling more than two million gross tons. At the same time, Parsons-style steam turbines and the first ocean-going marine diesels opened two propulsion paths that would define the next century.

British shipbuilding from iron to steel, turbines, and diesel
A shipbuilding history explains why steel displaced iron, how Britain's industrial lead translated into lighter and stronger hulls, and why turbines and marine diesels reshaped propulsion before 1914.
