Talk:8inch Triple Gun Mount Mk.9/@comment-44299528-20191102003305/@comment-2605:6000:1715:4096:2D5D:B201:E284:8AFF-20191102033010

It was the mk. 12 and mk.15 that were 17 tons. mk. 14 was still 30 tons like the original mk. 9.   I highly suspect it's because of the mount design for the Pensacola and Northampton classes didn't allow it for whatever reason. It should be noted Minneapolis one of the three new Orlean class cruisers to carry the mk.9/14 guns later carried switched to the mk. 15 during the war. New Orleans probably didn't recieve the mk. 15 because she wasn't in the dry dock as long as Minnie and probably the priority of mk. 15 went to the new constructed Balitmore class ships.
