Number Three 6/47 triple gun turret, showing the effects of a Japanese shell that struck the turret's 6½-inch class A armor face plate during the Battle of Cape Esperance, 12 October 1942. Photographed at the Philadelphia Navy Yard in November 1942, as the ship was receiving repairs. The shell, of unknown caliber, exploded on impact. It did relatively little damage to the armor, but its fragments riddled nearby structure and gouged the turret's guns. The explosion also destroyed the leather gun bucklers. Official U.S. Navy Photograph, now in the collections of the National Archives.
