The US and others have fallen into the trap of preparing for the next big war by looking at the last (WWII). Did anyone see the recent opening ceremonies at the Olympics? It included a presentation of 1800 drones flying in precise coordination. It does not take much imagination to see potential of drone swarms on the battlefield.

No one has great plans for swarms but everyone is looking into ways of dealing with them. One reason they're not giving up on it entirely is that using tons of quadcopters like make up those aerial displays is they have pretty low capacity which limits the damage they can do. Control software is also still an issue because it's unlikely gps will be still usable around ships so you need way better software guidance than the display swarms have.

They're definitely going to be one of the major challenges in the next major war but we're still in the early stages of both offense and defense for drones and drone swarms.

Drone swarms are useless for blue water naval combat. Drones cheap enough to build in large numbers don't have sufficient range, speed, or sensors. But navies are actively developing large, expensive drones to supplement or replace manned tactical aircraft.

What makes you think the US government isn't investing in drones? Heck, just google "drone strikes"
