The 15 cm/50 41st Year Type gun (50口径四十一式15cm砲, 50-kōkei yonjū-ichi shiki 15-senchi hō) was a naval gun used by the Imperial Japanese Navy before and during World War II. It had a 152 millimetres (6.0 in) bore with a length of 7.6 metres (25 ft) (50 calibre) and fired 45.4 kilograms (100 lb) shell for a distance of 18,000 metres (20,000 yd) (in single mount version) or 21,000 metres (23,000 yd) (in the later twin mounts). The gun was first used in single casemates on the Kongō-class battlecruisers and Fusō-class battleships and later in the Agano-class light cruisers in twin mountings.
