My idea is to have a hybrid airship like aeroscraft, but instead of having propellers it would have externally mounted VTOL drones which it could launch and recover. During normal operations the refueling and rearming would be staggered so there's always a fraction of the drones connected to the ship keeping it at high altitude, although it would not be able to have much if any forward thrust. The ship would still be able to launch all the aircraft at once by either being loaded lightly or by falling until the drones get back. Thanks to the large size and mass of the ship compared to the net downward force (weight minus the buoyant force), the ship would fall rather slowly. The ship would hold operators, fuel, munitions, and/or cargo.
But you may ask, "why not just have surface transports do this?" Well, transportation by would be faster and amphibious, and could also be safer.
Anyways, just a thought I had today.
