Drones have been an absolute game changer. The cost of one/more drones versus the cost of a ship is mind boggling.
So long as the targets haven't evolved defenses. The US Navy seems to be doing pretty well against the stuff Iran is throwing up. I like their use of the CIWS the other day. Very cheap in that it only expends a thousand or so 20mm rounds instead of a multi-million-dollar missile. Lasers will do even better. Bring 'em on!

That said, sea drones based on jet skis seem to sink ships pretty well and are apparently possibly within the budget of a home hobbyist let alone an even poor nation. Game changer indeed.
