The U.S. Navy's Nimitz Class aircraft carriers are some of the most powerful weapons systems known to man, floating cities that can take strike warfare capability to the far reaches of the planet, places unreachable by other military assets.  With an embarked air wing these carriers are manned by 5,500 sailors (and a few Marines) and home base for more than 80 airplanes.


Here are the places that make these 97,000 ton ships work:

The Nimitz Class carrier's two reactors are what puts the nuke in nuclear power. This amazing energy source allows the carrier to sail for up to 25 years before refueling.
