Nevada and Oklahoma machinery split

Within the Nevada class, the U.S. Navy gave Nevada steam turbines and Oklahoma triple-expansion steam engines. Expecting sister ships with different power plants and response characteristics to maneuver together raises an operational problem. Nevada may have sustained top speed longer while Oklahoma may have achieved the quoted cruising range more readily, although these are informed judgments rather than demonstrated measurements. The machinery split affected standardisation, formation handling, endurance, and the logistical burden hidden inside a nominally common class.
