France, Belgium, Japan and U.S. Forces Complete Group Arabian Sea Warfare Exercise

By Commander U.S. Naval Forces Central Command Public Affairs |

ARABIAN SEA – France, Belgium, Japan and U.S. forces conducted a Group Arabian Sea Warfare Exercise (GASWEX) in the Arabian Sea and Gulf of Oman, March 19-22.

Led by the French Marine Nationale’s Charles De Gaulle carrier strike group, this combined, multilateral surface, air and sub-surface training is the first major multilateral exercise conducted since commencing their Clemenceau 21 deployment in February.

“The capability to train in such conditions of realism and complexity certainly represented a challenge but also and above all a real opportunity. It put the capabilities of the Charles de Gaulle carrier strike group with its American, Belgian and Japanese partners into high-end operations to ensure the security in any strategic area where our shared values would be at stake,” said Admiral Marc Aussedat, commander of TF473, French carrier strike group.


Units involved from the Charles De Gaulle carrier strike group included the aircraft carrier FS Charles De Gaulle (R 91) and its carrier air wing (20 Rafale marine fighter aircraft, 2 E2C Hawkeye, helicopters Caïman marine and Dauphin), auxiliary ship FS Var (A 608), frigates FS Provence (D 652) and FS Chevalier Paul (D 621), Belgian frigate BNS Leopold I (F 930) and Japanese destroyer JS Ariake (DD 109), a French SSN and an Atlantic 2 maritime patrol aircraft.

“We conducted a multilateral exercise with the French Navy, the Belgian Navy, and the U.S. Navy in the Gulf of Aden, an important area for Japan’s sea lines of communications,” said Cmdr. EZAWA Naritaka, commanding officer of JS Ariake. “We believe this exercise was a significant effort to protect the maritime order of the Indian Ocean, while deepening cooperation and trust with the participating navies.”

During the exercise, participating forces focused on the full spectrum of maritime warfare operations, practicing anti-air warfare (AAW), anti-surface warfare (ASUW), and anti-submarine warfare (ASW) tactics and procedures.

Participating forces exercised the ability to operate aircraft from different partner nation ships, hunt enemy submarines, provide layered defense against air and surface threats, and conduct long range maritime strikes against simulated adversarial forces.

“GASWEX was a unique opportunity for our combined forces to practice the full breadth of our mutual combat capabilities,” said Brig. Gen. Farrell Sullivan, commanding general of Commander Task Force 51/5. “Our Marines and Sailors gained invaluable maritime security experience operating alongside their French, Belgian and Japanese counterparts.”

U.S. forces participating in the exercise included the amphibious assault ship USS Makin Island (LHD 8) with F-35B Lightning II joint strike fighters and MV-22 Osprey tiltrotor aircraft from the 15th Marine Expeditionary Unit (MEU), guided-missile cruiser USS Port Royal (CG 73), P-8A Poseidon multimission aircraft, and U.S. Air Force E-3 Sentry airborne warning and control system aircraft.

Exercises like GASWEX 21 improve operational effectiveness and enhance interoperability of our combined and joint force.

“Partnership is fundamental to everything we do, and those partnerships are our asymmetrical advantage,” said Vice Adm. Samuel Paparo, commander of U.S. Naval Forces Central Command (NAVCENT), U.S. 5th Fleet and Combined Maritime Forces. “Integrating processes, systems, and command and control functions strengthen relationships and trust – neither of which can be surged in time of crisis.”
