None of the airship concept art in that article looks like it passes a simple weight-to-lift ratio check. Real airships have a tiny usable compartment relative to the total size of the vessel, and everything is optimised for weight.<p>And sure, carrying one, or a few small planes is possible. But real combat planes are heavier, they require more fuel, ammunition is heavy, especially if we want something beyond basic machine gun rounds. And of course we will need crew, including life support. Leaving the planes hanging under the belly is no good if we want to do basically any kind of maintenance, even loading ammunition could be tricky in this position. But an indoor hangar, and mechanisms for getting planes in and out is just more weight. Realistically we will end up with way fewer and smaller planes than any seaborne aircraft carrier can support.<p>There are suggestions of adding something reminiscent of ship deck guns, but there is no way we have weight budget for that with all the planes, and I doubt the frame of the whole ship is actually rigid enough to absorb the shock of firing a big cannon. I think some light machine gun placements will have to do.<p>We also got the suggestion of the whole thing flying so high that it would be out of range of land-based AA weapons. That sounds neat, but the higher we want to fly, the less lift we get per volume, and we already spend a good part of the lift on just the hull, engines and fuel, we can't actually go terribly high before the number of planes supported drops to 0.<p>But for all this trouble, we will get a fortress in the sky! A fortress made of balsa wood and paper-thin skin that is. Minor bullet holes is one thing, the helium leaks really really slowly. But say someone drops a fire bomb on top of the hull, helium rushing out might extinguish the fire, but not until there is already a pretty big hole for that helium to rush out through. Basically our carrier is really big, really expensive, and really easy to hit.
