Airplanes do more than keep away other airplanes. They're also useful to blow up the enemy ashore, close air support for the grunts, deep tactical missions to isolate the battlefield.
You're still going to need flying machines. Need some way to get them close to the battlefield. This might not Ford class super carrier but it's going to be _some_ kind of carrier.
Let's say you wanted to protect the west coast of the U.S. You'd deploy 80 or 90 of these things (underwater, of course) along the shore. Every so often, one would surface, illuminate the skies with powerful radar, take out several targets, then disappear. Maybe it all happens inside of ten minutes. Then it relocates. Now picture that happening over a wide area with scores of ships.
My numbers might be off, but you could get total coverage and not really present a target for counter-attack. And maintain that coverage for months or years without having to worry about refueling, port calls, a logistics train, or personnel issues.
Lasers will change things in a big way, including creating completely new types of ships.
