I'm not an expert but I was in the military a decade or so ago. The Coast Guard and DHS definitely do partner operations in international and state-run waters for interdiction; the Navy definitely did similar interdiction operations with their smaller boats usually with partner nations. The Navy shooting missiles at alleged narco boats is new. At most the Navy and Coast Guard would engage to defend or disable. There's documentaries on streaming services where they put this on full display.
