In Hong Kong
USS Ronald Reagan (CVN-76) is at anchor in the port of Hong Kong along with guided-missile destroyer USS Chafee (DDG-90).
The two ships are part of the Navy’s forward-deployed Task Force 70, the service’s largest operational battle group.
The task force is composed of Carrier Air Wing (CVW) 5 and Destroyer Squadron (DESRON) 15. The leadership of both the task force and DESRON 15 have changed following continuing results of investigations following two fatal collisions in the Western Pacific.
In Sasebo, Japan
USS Bonhomme Richard (LHD-6) returned to homeport in Sasebo, Japan, on Sept. 25 after four months of operations in the Western Pacific.
In the Red Sea
The America Amphibious Ready Group (ARG), 15th Marine Expeditionary Unit (MEU) and Amphibious Squadron (PHIBRON) 3 are operating in the Red Sea.
The ARG includes amphibious assault ship USS America (LHA-6), amphibious dock landing ship USS Pearl Harbor (LSD-52) and amphibious transport dock USS San Diego (LPD-22).
In the Persian Gulf
The Nimitz Carrier Strike Group is conducting anti-ISIS strikes in Syria and Iraq in support of Operation Inherent Resolve.
The CSG has been conducting operations in the Persian Gulf since Aug. 1.
In the Western Atlantic and the Caribbean Sea
USS Gerald R. Ford (CVN-78) is underway for training.
Amphibious assault ships USS Wasp (LHD-1) and USS Kearsarge (LHD-3) and dock landing ship USS Oak Hill (LSD-51), along with the Marines of the 26th MEU, are providing humanitarian relief efforts for Hurricanes Irma and Maria.
Hospital ship USNS Comfort (T-AH-20) got underway from Norfolk on Friday and is steaming toward Puerto Rico. Comfort changed her homeport to Naval Station Norfolk, Va., in March 2013, a move that placed the ship closer to supplies and the medical crew, most of which come from Naval Hospital Portsmouth, Va.
Comfort is credited with a top speed of 17 knots. At top speed, she will arrive off Puerto Rico by late today or early Wednesday.
Wasp has been re-tasked from providing humanitarian relief in Dominica to provide support for Puerto Rico.
In addition to these major formations, not shown are thousands of others sailors and Marines serving aboard submarines, individual surface ships, aircraft squadrons, SEAL teams, Special Purpose Marine Air-Ground Task Forces and other units around the globe.
