A gun for large-sized light cruisers developed in the Country of Tea under the London Naval Treaty.
In order to get around the displacement limits set by the Treaty, these 6inch triple-mounted guns were deployed as the main guns of heavy-cruiser-sized light cruisers.
It was deployed on many light cruisers from the Country of Tea, such as the Town-class light cruiser.
