Yamato's main battery consisted of nine 46 cm (18.1 in) 45 Calibre Type 94 naval guns — the largest calibre of naval artillery ever fitted to a warship. Each gun was 21.13 metres (69.3 ft) long, weighed 147.3 tonnes (162.4 short tons), and was capable of firing high explosive or armour piercing shells 42 kilometres (26 mi).[22] Her secondary battery comprised twelve 155-millimetre (6.1 in) guns mounted in four triple turrets (one forward, one aft, two midships), and twelve 127-millimetre (5.0 in) guns in six twin mounts (three on each side amidships). In addition, Yamato carried twenty four 25-millimetre (0.98 in) anti-aircraft guns, primarily mounted amidships. When refitted in 1944 and 1945 for naval engagements in the South Pacific, the secondary battery configuration was changed to six 155 mm guns and twenty four 127 mm guns, and the number of 25 mm anti-aircraft guns was increased to 162.
