I saw a piece on TV somewhere, History Channel maybe or PBS, about converting Trident submarines into semi trucks of the sea, capable of dispensing pods of various sorts of fighting units. Could no way begin to fully replace carriers -- even if they could be fitted to launch a fighter plane, say one with foldable wings that could open after launching from some device, there's no place for the plane to land. Pontoons maybe?

One idea was to lauch capsules complete with landing craft, land vehicles, and troops.

Even as I'm writing, it seems hopelessly Rube Goldberg.
