When World War I began, Armstrong-Whitworth were building the battleship Almirante Latorre for Chile, armed with 10 of its 14-inch guns. The battleship was acquired by the British government and completed as HMS Canada and served in the Royal Navy in World War I, with its guns designated BL 14 inch Mk I.

After World War I the battleship was sold to Chile as Almirante Latorre as originally intended.

Railway guns

Elswick built several guns for Japan which went into British service as railway guns in World War I under the designation BL 14 inch Mk III. They were similar to but lighter than Mk I, and were modified to give similar performance as Mk I.
