The ARA Piedrabuena Oceanic Patrol Vessel has been deployed by Argentina's Joint Maritime Command in response to an increase in illegal fishing operations by foreign vessels, primarily from China. The foreign fleet, which includes over 400 boats, poses a threat to local fishermen and endangers the Argentine illex squid. The patrol vessel has been assigned to combat illegal fishing in Argentina's territorial Exclusive Economic Zone and also covers Maritime Search and Rescue tasks in the Ushuaia Search and Rescue Coordination Center.
