United States Navy - Wikipedia, the free encyclopediaThe U.S. Navy is the largest in the world; its battle fleet tonnage is greater than that of the next 13 largest navies combined. The U.S. Navy also has the world's largest carrier fleet, with 11 in service, one under construction (two planned), and one in reserve. The service had 328,516 personnel on active duty and 101,689 in the Navy Reserve in January 2011. It operates 286 ships in active service and more than 3,700 aircraft.
Also factor in the fact that any war with another major power is certain to be nuclear, meaning these ships are useless when it comes to China and Russia, and that the size of our navy doesn't tell the whole story because we also have the best technology, and I really can't comprehend why we need such a large navy. Can any of you?
