| has gloss | eng: The British BL Mk I naval gun was a naval gun in the service of the Royal Navy during the First World War. It was the largest and heaviest gun ever used by the British. Only the Second World War Japanese 40 cm/45 Type 94 had a larger calibre, , but the British shell was heavier. The gun was a scaled up version of the BL 15 inch Mk I naval gun and was developed to equip the large light cruiser (a form of battlecruiser) . Three guns were built, but they did not see combat with Furious as they were removed from her and transferred to the s and for coast bombardment duties. Only 85 rounds were fired in anger before the war ended. All three were removed from service in 1920 and served as proving guns for cordite tests. Two were scrapped in 1933 and the last one survived until it was scrapped in 1947. |
