Work on "West Virginia" saw the ship radically altered. In addition to the torpedo bulges, her superstructure was completely revised, with the old heavily armored conning tower being removed and a smaller tower erected in its place to reduce interference with the anti-aircraft guns' fields of fire. The new tower had been removed from one of the s that had recently been rebuilt. The foremast was replaced with a tower mast that housed the bridge and the main battery director, and her second funnel was removed, with those boilers being trunked into an enlarged forward funnel. The ship's weapons suite was also overhauled. She received air-search radar and fire-control radars for her main and secondary batteries, the latter being replaced by a uniform battery of sixteen 5-inch/38 cal. guns in eight twin mounts. These were controlled by four Mk 37 directors. The light anti-aircraft battery was again revised, now consisting of ten quadruple Bofors guns and forty-three 20 mm Oerlikons.
