There are two Carrier Fleet Logistic Support squadrons-one on each coast. VRC-30 is based at Naval Air Station North Island, VRC-40 is based at Naval Station Norfolk. These squadrons send two-plane detachments with each deploying aircraft carrier.
The U.S. Navy has 10 aircraft carriers, nine amphibious assault ships, 22 cruisers, 62 destroyers, 17 frigates and 72 submarines. In addition to ships, the U.S. Navy has 3,700 aircraft, making it the second largest air force in the world. At 323,000 active and 109,000 personnel, it is also the largest navy in terms of manpower. What makes the U.S. Navy stand out the most is its 10 aircraft carriersâmore than the rest of the world put together. Not only are there more of them, theyâre also much bigger: a single Nimitz-class aircraft carrier can carry twice as many planes (72) as the next largest foreign carrier.
