Among naval historians, the US Navy 5"/38 caliber gun is considered the best intermediate-caliber, dual purpose naval gun of World War II.  Unlike later lighter-weight marks intended for aircraft carriers, cruisers and destroyers, the 76-ton "Mark 28" version of the twin mount was designed specifically for battleships and was mounted on ships of the North Carolina Class, South Dakota Class, and Iowa Class.  This mark was likely the type mounted to early Atlanta class cruisers
