Or maybe, the current state of the art of missiles, is superior to that strategy?
Consider 1 hypersonic missile, 1 supersonic missile, and maybe 10 subsonic missiles, all cruise missiles flying no higher than 100m off the ground.
Since they're so low, they can only be physically detected at a range of 10km (they're literally "behind the horizon" and cannot be detected beforehand).
With proper timing: all 12 targets pop up on the horizon simultaneously. The 10 subsonic missiles will hit the ship in 30-seconds, the supersonic missile will hit the ship in 15-seconds, and the hypersonic missile will hit the ship in 5-seconds.
They are all flying at a randomized flight pattern at ~2G lateral movements. Its not like missiles fly straight at their targets these days, they fly monte-carlo randomly to throw off defense systems.
------------
Now consider the drone swarm flying at 100mph that crossed over the horizon with the 12 cruise missiles. The Drone Swarm will arrive in 2+ minutes. Do your defense systems even care?
Do the drones have any significant amount of lateral G's that they can pull? Can they fly at 2G random flight patterns to throw off air defenses?
