Perfectly reasonable. Yet one would think that with the right software the radar could distinguish the faster vehicles and use the missiles more sparingly.
So something else needs to be used as well, or we need a lot more Phalanx CIWS on ships with deeper magazines.
Yep. That was obvious two years ago.
Some of the antiship missiles and some of the drones can fly at about the same speeds. There are loitering antiship missiles these days, just like there are loitering drones, and they can be roughly the same size and radar return. It’s not just a matter of “the faster ones are the lethal missiles” - additionally, some of the drones are large enough to be loaded with anti-armor warheads and used as suicide drones, turning them into small antiship missiles as well.
Keep in mind that some of the Houthi drones are not “child’s toy” but a significant fraction of the size of a real aircraft, or the size of a conventional missile, so they can carry a decent payload or warhead. It’s how they’re sinking merchant ships.
