This was the standard armament for most U.S. light cruisers. A dual mounting with antiaircraft capability was under development when the war ended.

The gun was designed for very rapid fire, but while its super-heavy shells had excellent penetration, they also proved to have a defective fuse design, giving a very high percentage of duds during the crucial battles in the Solomons.
