Trivia

The 15.2cm guns were originally designed by Vickers as secondary weapons for the battlecruiser Kongo, which was built in Britain by Vickers-Armstrong (Barrow). The Japanese version was designed by Engineer Hata Chiyokichi and adopted in 1908. In the Japanese Navy, Vickers-built guns were designated as Mark II while those built in Japan were designated as Mark III. The design itself was outstanding at its time, but 15.2 cm shell proved too heavy for Japanese sailors and had inferior firing rate (circa 6rpm), thus the lighter variant of 14cm caliber was later designed in-house.

When the 'Kongo-class was modernized in the 1930s, these guns were removed and reused on the Agano-class light cruisers in new twin mountings. There are also some coastal defense batteries at Guam were also equipped with these weapons.

This type of gun comes in a casemate mounting and would be mounted in an armored room along the side of the ship known as a casemate. Casemates too close to the waterline or too close to the bow of the ship were prone to flooding thus making the gun ineffective.
