339:-class—allows a gas driven turbine to run generators. This generator can produce electricity to move the ship and also operate a variety of its instruments and accessories. A lot of these electricity-generating turbines are being produced to include integrated electrical propulsion. Integrated electrical propulsion is when the engine strictly runs off of electricity, without the use of any gasoline, diesel, or fuel for that matter. The electric engine is more efficient due to only being electric and not gasoline based. It allows for less pollution and provides electricity to the naval ships instruments and applications. A lot of these electricity-generating turbines are being produced to include integrated electrical propulsion. A good example of one of these systems is the COGAL (combined gas and electric) system.
354:. Electric driven propulsion allows for movement of the ship and provides power generation on-board of the ship. Heat lost by gas turbines is not practical because it is wasting energy as heat dissipates into the surroundings. The COGES system allows the heat to be captured and converted into steam for the generation of electricity. Unlike diesel and other heavy-fuel turbines, the COGES captures the left over heat and exhaust from the turbine and it reduces pollutants from escaping into the atmosphere. The COGES system allows for practical applications in cruise ships, for example the

Gas and steam turbines are most efficient at thousands of revolutions per minute. This is a major drawback because of the need for heavy gears, which drive the engine into one single duty, propulsion. Electric motors provide numerous applications including use of accessories besides that of

Warships require the ability to cruise efficiently for long distances and also to have high power for intermittent bursts of speed. For that reason they use combined power systems that use an efficient prime mover, such as a

or a small gas turbine, for cruising and large gas turbines for high speed. Most of these use mechanical combination of power, through gearboxes and clutches, with systems such as
