The State Department has issued a document regarding US policy for the suppression of Piracy of the Horn of Africa (HOA) and in the Gulf of Guinea (GOG). It is a brief four page intro and two annexes, eight pages addressing the HOA and ten addressing the GOG.
The link on the State Dept. website is here.
The Coast Guard is mentioned:
“Provide persistent interdiction-capable presence at sea off the HOA. Consistent with other U.S. mission requirements, U.S. Navy and/or U.S. Coast Guard forces operating in the region provide persistent interdiction through presence, conduct maritime counter-piracy operations, and coordinate counter-piracy activities with other forces operating in the region to the extent practicable. When in range, these forces will prevent suspected pirate vessels from operating, respond to reports of pirate attacks with the objective of disrupting such attacks, and, in appropriate circumstances, terminate the act of piracy and any resultant hostage situation with intent to deliver any surviving pirates ashore for prosecution. These forces will also coordinate efforts among all multilateral coalitions such as Combined Maritime forces, NATO’s OPERATION OCEAN SHIELD, the European Union’s OPERATION ATALANTA, and independent naval forces.”
