The United States has 11 aircraft carriers.
Here are where our carriers currently are: 1 underway to the South China sea, 1 deployed in Japan to be ready to respond to North Korea, 1 deployed in Japan to help in relief efforts, 1 deployed in the Red Sea heading to the Suez Canal, and 1 in the Arabian Sea.
We have 1 additional carrier ready to be deployed in case WWIII breaks out tomorrow. The rest (5) are under-repair.
At the start of the Arab protests, the US had no carriers deployed in the Mediterranean. Instead, we are relying on the French working over-time to get their carrier out of the docks, and the Spanish being generous enough to deploy their own despite being borderline bankrupt. I do not know if the Italians have deployed theirs, and the British no longer have a carrier worthy of the name. None are comparable to US carriers: the French one is less than half the size of a standard US carrier.
Just something to keep in mind the next time someone tells you we need to cut the military budget by 50%.
