"Anyway, the point of power-projection is that these bases are mobile. As we finish up our job in Afghanistan / Iraq, we can move these super-carriers elsewhere for support. Puerto Rico was serviced by a super-carrier Abraham Lincoln for instance (hospitals on board, + Helicopters delivered supplies), while the Super-Carrier Ronald Regan helped Japan clean-up the Fukashima Nuclear disaster."

I know that's reality but using aircraft carriers for disaster relief is an awfully expensive way to do this.

I'm unsure if any other sea-bearing vessel has a ton of helicopters that can deliver supplies to and from a remote area (ie: Puerto Rico once all the roads were wiped out by Hurricane Maria).

Helicopters need an area to land and refuel. The pilots need an area to sleep. Carriers seem like the ideal service vehicle.

And sure, the Nimitz class carrier, with two nuclear reactors and outfitted with enough weaponry to take on entire countries... is a bit overkill. But there are benefits to a mobile super sea-base.

The alternative is to build a ton of smaller carriers... but smaller carriers can't launch airplanes. You need a large area so that planes can land. Airplanes like Airborne early Warning (https://en.wikipedia.org/wiki/Airborne_early_warning_and_con...) can be launched from super-carriers.

Once you have radar-dishes in the air however, you now need to think about how to defend those radar-dishes from enemy fighters. And then we get the F35.

While carriers are certainly used in this role, I've taken part in two such missions while deployed with the USS Ronald Reagan, there are ships that are more capable in handling humanitarian and disaster relief, and non-combatant evacuation efforts, such as LHDs -- which also have a larger complement of helicopters/V-22s and ground-troop support than a carrier.

Outside of the US supercarriers, all other carriers are smaller, and many launch planes (often V/STOL aircraft, particularly commonly Harriers.)

[dragontamer]

Fair. But still, the point stands. The shorter the runway, the fewer planes you can launch.

And yes, there's a catapult to help launch the planes, but the longer the runway, the less stress you put on the planes, and the more kinds of airplanes can land on your carrier.

US Supercarriers have more than just fighter-jets, they also have larger cargo aircraft like: https://en.wikipedia.org/wiki/Grumman_C-2_Greyhound. Capable of delivering 5-tons of cargo over 1300 miles.

I don't believe Britain (which does have fleets of smaller carriers) have any support for such a large cargo-aircraft. They're limited to helicopter delivery. Long-range delivery is most efficient with wing-aircraft.

I'm not an expert on the HMS Queen Elizabeth carrier. Are you aware of any cargo-aircraft ability of the smaller carrier? (And mind you: The Queen Elizabeth is the 2nd largest carrier-class in the world. So even if it can do it, the fact remains that you need to build BIG carriers if you wish to support remote delivery of cargo through aircrafts)

One of the consequences of the F-35B being late and over budget is that the uk now have a brand new carrier with no fixed-wing planes.
