BL 18 inch / 40 naval gun
The British 18 inch naval gun was the largest gun ever in the service of the
Royal Navy. The official designation was "18 inch /40 Mark I". The gun was up-scaled from the BL 15 inch /42 naval gunand proved accurate and reliable. Only the Second World WarJapanese 40 cm/45 Type 94had a slightly larger calibre, 18.1 inches, but the British shell was heavier.
A total of 3 guns were built by
Armstrong Whitworthin Elswick. One gun was installed in the "large light cruiser" (a form of battlecruiser) HMS "Furious" in a single turret, but was removed after trials showed the vessel could not handle firing and she was converted into an aircraft carrier. Two other guns were mounted in the "Lord Clive" monitors "General Woolfe" and "Lord Clive" and were used for bombarding German occupied Belgiumin 1918. Two guns were scrapped in 1933 and the third was used for trials until it too was scrapped in 1947. A total of 85 18" shells were fired in action.
