Hey, I have a great idea for transportation! Pods!
--- every startup these days.
Always a bunch of tech bro's who want to reinvent the train but worse, made an animation of it and somehow manage to hoard in millions for just a dumb concept which would never work.
There is also the concept of a cargo plane which can drop drone swarms. A few drones are for jamming, some have radar, some have missiles to take out anti air systems and the rest are duds (to saturate defenses) or carry a payload for kamikaze to hit the actual target. The plane loiters outside enemy range while dropping 100 to 500 drones. Thing is, drones don't need a large platform. You can even easily convert a small attack submarine to a subsurface drone carrier if you like.
