BB27 Michigan BB26 South Carolina |
The first American dreadnoughts mounted the same broadside as Dreadnought, but requiring 2 fewer barrels. The design's weakness was in the refusal to adopt steam turbines, instead keeping the triple expansion engines. |
|
BB28 Delaware BB29 North Dakota |
The Delawares added 2 more 12" guns, and had a heavier secondary armament. Whilst Delaware had triple expansion engines, North Dakota was the first American battleship with steam turbines. |
|
BB30 Florida BB31 Utah |
The Floridas were enlarged Delawares, but were planned with 8 14" guns, which were not developed in time. They were the first American battleships with 4 shafts. |
|
BB33 Arkansas BB32 Wyoming |
The Wyomings were enlarged Floridas, and were designed with triple turrets. As this was not available, a unique 6 twin turret layout was adopted. |
|
BB34 New York BB35 Texas |
The New Yorks reverted to triple expansion machinery as the standards for the steam turbines set by the navy were refused by the builders. They were the first American battleships to mount 14" guns. |
|
BB36 Nevada BB37 Oklahoma |
The Nevadas were the first American battleship with all or nothing protection. Oklahoma kept to triple expansion machinery, while Nevada readopted steam turbines. |
|
BB39 Arizona BB38 Pennsylvania |
The Pennsylvanias were the first American battleships with triple turrets. Cruising turbines were fitted on the wing shafts to increase range. |
|
BB42 Idaho BB41 Mississippi BB40 New Mexico |
New Mexico became the first major warship to be fitted with turbo electric drive whilst the others retained geared turbines. In the interwar years all were modernised. |
|
BB44 California BB43 Tennessee |
The Tennesees were improved New Mexicos. Both were sunk at Pearl Harbour, and, after salvage, were effectivly rebuilt. |
|
BB45 Colorado BB46 Maryland BB47 Washington BB48 West Virginia |
The Coolorados were the first American battleships to mount 16" guns, the decision being influenced by the Japanese Nagatos. |
|
BB50 Indiana BB53 Iowa BB54 Massacusetts BB51 Montana BB52 North Carolina BB49 South Dakota |
None of the South Dakotas would be completed due to the Washington Treaty. Protection was considerably improved on their predecessors. |
|
BB55 North Carolina BB56 Washington |
The North Carolinas were designed with 14" guns in quad turrets, but Japanese secrecy about their intentions forced n increase to 16". |
|
BB60 Alabama BB58 Indiana BB59 Massachusetts BB57 South Dakota |
The South Dakotas were improved versions of the North Carolinas. Protection was improved, but the increased beam meant that they were slower then their predecessors, even with more installed power. |
|
BB65 Illinois BB61 Iowa BB66 Kentucky BB63 Missouri BB62 New Jersey BB64 Wisconsin |
The Iowas were the ultimate in American battleship design, and have proved amongst the most military projects in history. Increased length and engine power created the fastest battleships built, and they were also very manouverable. |
|
BB71 Louisiana BB69 Maine BB67 Montana BB70 New Hampshire BB68 Ohio |
The Montanas were intended to be enlarged Iowas, with speed traded for protection. Wartime priorities and economies meant than none would be built. |
