Sea going aircraft carriers are obsolete. They need to be replaced by mile long dirigible trains.
These trains would be made up of hybrid dirigible blimps like the design you see pictured below. Such trains would become a combination assault drone, AWACS, and logistics platform.
They would be protected by swarms of Drimes, or drone proximity mines. There would litteraly be thousands of these, say, 5 to 10 kilo Drimes surrounding the train. The train would support them by deploying tethered recharge/control nodes that would be set up to handle the recharge turnaround of something on the order of 50 to 100 Drimes.
The Drimes themselves would employ a claymore type, shrapnel explosive, with active directional control, to provide the best bang to payload ratio, while still allowing for significant battery load.
Such Max-Tac (or maximum tactical) train platforms would be able to loiter indefinitely at 30 to 40 thousand feet because any Drib (dirigible blimp) segment would be capable of independent flight. As such, end Dribs could attach and reattach as needed for resupply on an ongoing basis. And if the military could come up with some form of reusable, steerable, parafoil drop pallet for 50 to 100 ton loads, the system would be complete.
Like I said. Just a thought.
