If sub launched drones can eventually engage in precision bombstrikes and air-superiority operations, this could presage another shift in naval warfare.
It used parts of the Tomahawk system, the precision bombing was largely covered. Drones are supposed to be cheap. Billion dollar delivery platforms don't really align with that. This is the US Navy trying to keep a weapon system designed for the cold war. An attack submarine that isn't stalking boomers is a hole in the water into which money is poured.
That only applies to this iteration. I don't see any reason why submerged drone launches couldn't be made cheaper.
