This nuclear reactor was used in the world's first nuclear-powered aircraft carrier, the USS Enterprise (CVN-65). The four propulsion plants on Enterprise each contained two reactors, numbered according to the shaft they powered, 1A-1B, 2A-2B, 3A-3B, and 4A-4B. Each propulsion plant was capable of operating on one reactor plant through most of ...
A CODLAG system employs electric motors which are connected to the propeller shafts (usually 2). The motors are powered by diesel generators.For higher speeds, a gas turbine powers the shafts via a cross-connecting gearbox; for cruise speed, the drive train of the turbine is disengaged with clutches.
Turbo generators are used for high shaft rotational speeds, typical of steam and gas turbines. The rotor of a turbo generator is a non-salient pole type usually with two poles. [5] The normal speed of a turbo generator is 1500 or 3000 rpm with four or two poles at 50 Hz (1800 or 3600 rpm with four or two poles at 60 Hz).
As Navy planners developed requirements for the Gerald R. Ford class, they concluded that the A4W reactors that powered the previous Nimitz-class aircraft carriers offer too little power for current and anticipated future shipboard needs, [2] and decided to commission a new reactor design from Bechtel Corporation, [3] which has "performed ...
The General Electric LM6000 is a turboshaft aeroderivative gas turbine engine. The LM6000 is derived from the CF6-80C2 aircraft turbofan.It has additions and modifications designed to make it more suitable for marine propulsion, industrial power generation, and marine power generation use.
An example of integrated electric propulsion in the Type 45 destroyer (GT: gas turbine; DG: diesel generator) Integrated electric propulsion (IEP), full electric propulsion (FEP) or integrated full electric propulsion (IFEP) is an arrangement of marine propulsion systems such that gas turbines or diesel generators or both generate three-phase [1] electricity which is then used to power ...

Makin Island is the eighth ship of the Wasp class, but features noteworthy technological advances. Changes from the previous LHD design include gas turbine main propulsion engines, all-electric auxiliaries, an advanced machinery control system, water-mist fire-protection systems, and the Navy's most advanced command and control and combat systems equipment.
