This exercise brings together service members from each nation’s military in a combined effort to enhance interoperability in pursuit of common regional security goals. Service members from participating units plan, coordinate and conduct operations over land and at sea.
Vessels from each navy will plan and prepare amphibious landings and air assaults while also conducting formation maneuvers, air defense exercises and communication drills.
The culminating events are scheduled to include surveillance and insertion of forces via JSDF CH-47 Chinook helicopters from French Mistral-class amphibious assault ship Tonnerre (L9014), followed by a helicopter-borne assault via U.S. Marine Corps MV-22 Ospreys from USS New Orleans. Once all forces are together on the ground they will begin an assault on a shared objective.
