Money would be better spent on Cruise missile type drone and smaller surface cruising part sub part ship to carry them, and anti-satellite satellites. The next major war will require air superiority of a different sort, something more like orbital range superiority.
We already have deployed robo-kaze drones - many shapes, sizes and missions. Shhhhh....
I’d rather have 50,000 super-smart drones carrying a one-pound bomb each, semi-autonomous, solar-powered, and capable of targeting and recognizing an individual person.
Better yet, 250,000 drones the size of a butterfly capable of the above and carrying a one ounce bomb, that flies into the target’s ear.
