The picture of USS Nevada at the top of the article is of Nevada post rebuild:
Upon my return to Bremerton, a profound change was occurring in the silhouette of the Nevada’s superstructure, foremast, and smokestack. The 10 casemated guns had been removed, and eight dual-purpose twin 5-inch gun mounts were being installed. These guns were more suitable for defense against incoming enemy planes and could still be used against surface craft using modern electronic fire-control systems and computerized range-finding equipment to provide rapid firing and movement.
As built, Nevada (and other BBs) had casemate mounted 5"/51 guns on each side for defense from destroyers and other smaller craft. She also had a number of 3"/50 AA guns. After rebuild, Nevada had turret mounted dual 5"/38 dual-purpose guns for anti-ship and AA. These are the turrets that can be seen along the superstructure.
After a short stay in New York harbor to avoid a hurricane threat, the Nevada entered a drydock at Norfolk on September 18, 1944. The crew was given a 21-day leave while an interesting and unusual event took place. Our 14-inch guns were relined, and the guns in Turret 1 were replaced with tubes salvaged from—of all ships—the Arizona and Oklahoma, both stricken at Pearl Harbor.
BB main guns were rifles, and barrels had a finite life, after which range and accuracy would be significantly affected. Like Nevada, Arizona's and Oklahoma's main guns were 14"/45; Oklahoma was Nevada's classmate, and Arizona from the next class of BBs.
USS Nevada was used in but not sunk by the Bikini A-bomb tests.
