They were modified versions of the featuring improved underwater armor for better torpedo protection and 30-degree elevation on their main batteries, as opposed to 15 degrees for the ''New Mexicos''. Both ships were extensively rebuilt after being damaged during the attack on Pearl Harbor, and survived World War II to be scrapped shortly after. ==Class history== ''Tennessee'' and her sister ship ''California'', already incorporating many of the innovations in the , were the first American battleships built to a "post-Jutland" hull design. As a result of extensive experimentation and testing, her underwater hull protection was much greater than that of previous battleships; and both her main and secondary batteries had fire-control systems. Since ''Tennessee's'' 14 inch (356 mm) turret guns could be elevated to 30 degrees—rather than to the 15 degrees of earlier battleships—her heavy guns could reach out an additional 10,000 yards (9 km). Because battleships were then beginning to carry airplanes to spot long-range gunfire, ''Tennessee's'' ability to shoot "over the horizon" gave her a material tactical advantage. The ''Tennessee'' class, and the three ships of the which followed, were identified by two heavy cage masts supporting large fire-control tops, twin funnels and no secondary gun casemates in their hulls. These features distinguished the "Big Five" from the rest of the battleship force (older battleship classes had had their noticeably lighter cage masts replaced with tripod masts during inter-war modernization and were built with single funnels and casemates in their hulls). In the attack on Pearl Harbor, ''Tennessee'' was damaged by two bombs and ''California'' was sunk by two torpedoes and two bombs. Both ships (and ''West Virginia'' of the ''Colorado'' class) were extensively reconstructed into essentially new vessels. Their hulls were 'bulged' for better stability, superstructures were scrapped down to the deck and completely rebuilt, their secondary battery of 5 in (127 mm) 51-caliber anti-surface and 3 in (76 mm) 50-caliber anti-aircraft guns was replaced by a uniform secondary of 5 in (127 mm) 38-caliber dual-purpose guns, and they added a number of 20 and 40 mm anti-aircraft weapons. The twin funnels were replaced by a single funnel flared into the superstructure tower, similar to the newer . 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tennessee-class battleship」の詳細全文を読む スポンサード リンク
