Usa Destroyer
A hypothetical variant for the complete rearmament of USS Hull, a Forrest Sherman-class destroyer with advanced 203 mm Mark 71 guns developed in the 1970s under the Major Caliber Lightweight Gun (MCLWG) program. The program was aimed at creating guns capable of attacking Soviet coastal positions. The Mark 71 prototype was installed in the bow of USS Hull from 1975 to 1979.
