The 14 cm/50 3rd Year Type naval gun was a Japanese low-angle weapon introduced during World War I.
History
[edit]It served as the secondary armament in a number of Japanese dreadnoughts and as the main armament in light cruisers and some auxiliary ships. It was also the most common Japanese coast-defense gun during World War II. "Third year type" refers to the Welin breech block on this gun. Breech-block design began in 1914, the third year of the Taishō period. This breech-block design was also used on Japanese 40 cm (16 inch), 20 cm (8 inch), 15.5 cm (6 inch), 12.7 cm (5 inch), and 12 cm (4.7 inch) naval guns.[2]
This gun was not mounted aboard submarines. Submarine cruisers used the shorter-barreled 14 cm/40 11th Year Type naval gun.[3]
