I always wonder about the US Navy when I see reports of mass attacks by cheap(ish) drones against high value targets. Will there come a time when the US carrier based fleets are on the wrong side of that equation?
The new Ford class aircraft carrier costs an estimated $13 billion to build and outfit. Very well protected and with power projection that's unparalleled and unique to the US but ... the nations thought the same of the Battleship into the 1930s. Is the drone problem something that will (eventually) turn the page on the modern behemoth aircraft carrier?
($13B=13,000 ea $1,000,000 drones)
For the particular example you cite, the answer is probably "no". First of all, an aircraft carrier is actually pretty hard to find. It moves around enough that if you launch a lot of drones towards where your LEO satellite located it, by the time they fly the 300 miles (minimum) to get there, it will be many miles (30 minimum, probably more) away in an unknown direction. The drones will have to go find it. They can do this, but many of them will guess the wrong direction and not ever find the carrier. Of course that means they all have to carry a good radar, which pushes the price up. It also means they can't all be using their radar, as they will interfere with each other :-). How one manages that problem is a good question.
Of course, the E2 will have seen this swarm of drones approaching with almost constant bearing long before they get anywhere near the carrier. The carrier will sortie all fighters they have available to go "thin out" the swarm. As has been demonstrated at least twice in the middle east recently, that is quite doable and effective. An entire country that wasn't even moving was defended from drones :-). None got through. What did get through were a few ballistic missiles. Ukraine has also had significant success in defending against drone swarms with far, far, less counter air that a carrier can put up.

Even assuming there are quite a few "leakers" that eventually enter the Inner Air Defense Zone, the escorts (at a minimum, 3 guided missile combatants and possibly more in a "wartime" scenario) can engage lots of targets. The air wing in the air has to be reminded that the TAO has given the escort "weapons free" authority. Verify your mode 5 is on and working. Stay outside the IADZ until everybody has calmed down :-). That should do the job. If it doesn't the carrier herself has several CWIS RAM and also EA capability. Given all of the above, conventional long range drones are not going to be the problem. At least in exercises, this approach seems to work. That doesn't mean the Navy can "forget about it". They still need to maintain an adequate superiority to this kind of attack. One can thank the Russians during the cold war for sensitizing the Navy to the problem. The Russians are also good at using quantity as a weapon, so that was part of the drill.
Ballistic missiles are a different beast altogether. China is touting their DF-xx series missiles as "carrier killers". Different subject for a later post maybe, but not really "drone related".
