The carrier itself probably not to much. They are nuclear powered.
The Kitty Hawk is conventonaly powered and uses about 140 barrels an hour underway. So that would be about 3360 barrels a day. The John F. Kennedy is also conventional and is probably about the same.
A lot. The George Washington has tanks that can carry 1.4 million gallons at full capacity.
bout a million gallons including jet fuel
they're nuclear powered so they don't quite "burn fuel" per se. unless of course you're talking about oil.
