Counter-piracy and the US Navy's original mission

Is counter-piracy mainly a Coast Guard mission?

Local Coast Guard duties differ from overseas counter-piracy, and combating North African piracy was a founding US Navy mission.

Domestic maritime law enforcement differs from operations far from a nation's coast. The Coast Guard is designed principally for local and national waters. Counter-piracy in the Mediterranean or Indian Ocean needs a navy able to deploy and remain overseas. The early US Navy's operations against North African piracy show that this is a longstanding naval task.
