8" gun turret, USS Baltimore

Gun turrets 1,2, and 3 for the USS Baltimore and its derivative Oregon City class heavy cruiser, which saw action in the Second World War. A brief summary from Wikipedia about their exploits follows: "The Baltimore-class cruiser was a large class of heavy cruisers commissioned during or shortly after World War II by the United States Navy. Fourteen Baltimores were completed, more than any other class of heavy cruiser, including three ships of the Oregon City class sub-class. Fast and heavily armed, the Baltimore cruisers primarily protected fast aircraft carriers in battle groups from air attack during World War II. Their 8-inch (203 mm) main guns and secondary 5-inch (127 mm) guns were frequently used to bombard land targets in support of amphibious landings. After the war, only six Baltimores - St Paul, Macon, Toledo, Columbus, Bremerton, and Helena - and two Oregon City-class ships - Albany and Rochester - remained in service, while the rest were moved to the reserve fleet. However, all ships except Boston, Canberra, Chicago, and Fall River were reactivated for the Korean War. Except for St Paul, all ships retaining all-gun configurations had very short (18 years or less) service lives, and by 1971 were decommissioned, and started showing up in the scrap-sale lists. Nevertheless, four Baltimore-class cruisers were refitted and converted into some of the world's first guided missile cruisers, becoming two Albany-class and two Boston-class cruisers. The last of these was decommissioned in 1980, with Chicago lasting until 1991 in reserve. No example of the Baltimore class still exists today."
