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 ...
Electric power for the propulsion motor is conducted through slip rings that let the Azipod unit rotate 360 degrees about the vertical axis. [8] Because Azipod units utilize fixed-pitch propellers, [ 9 ] power is always fed through a variable-frequency drive or cycloconverter that allows speed and direction control of the propulsion motors.
A turbo generator is an electric generator connected to the shaft of a turbine (water, steam, or gas) for the generation of electric power. [ note 1 ] Large steam-powered turbo generators provide the majority of the world's electricity and are also used by steam-powered turbo-electric ships.

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.
A powership (or power ship) is a special purpose ship, on which a power plant is installed to serve as a power generation resource. Converted from existing ships, powerships are self-propelled, ready to go infrastructure for developing countries that plug into national grids where required. [1] Unmotorised powerships, known as power barges, are ...
The Francis Scott Key Bridge, a significant span over the Patapsco River in Baltimore, collapsed after it was struck by a Singapore-flagged container ship, 'Dali.' on March 26, 2024, in Baltimore, MD.
Nuclear reactors power aircraft carriers by the fission of enriched uranium to boil water, causing turbines to turn and generate electricity. This process is largely the same as in land-based nuclear power stations, but with one notable difference. Naval reactors directly use turboshaft power for turning the ship's screws. Over decades of ...
