In the Eastern Pacific
About 7,500 sailors and Marines with the Theodore Roosevelt Carrier Strike Group departed Oct. 7 from San Diego for a scheduled deployment to the Western Pacific and the Middle East.
They are steaming west and are currently about halfway to Hawaii.
The Roosevelt Strike Group is expected to ultimately relieve the Nimitz Strike Group in the Persian Gulf.
In the Gulf of Aden
The America Amphibious Ready Group (ARG), 15th Marine Expeditionary Unit (MEU) and Amphibious Squadron (PHIBRON) 3 have transited the Bab-el- Mandeb from the Red Sea into the Gulf of Aden. The Bab-el-Mandeb is a strait between Yemen on the Arabian Peninsula and the Horn of Africa and is about twenty miles across. In Arabic, Bab-el-Mandeb translates to the “Gate of Tears.”
The America 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 continues to conduct anti-ISIS strikes in Syria and Iraq in support of Operation Inherent Resolve.
In the Western Atlantic and the Caribbean Sea
USS Harry S. Truman (CVN-75) is underway in the fleet operations areas off of Norfolk, Va., conducting a Tailored Ship’s Training Availability (TSTA). This is the final step in the individual ship training period and culminates in a Final Evaluation Problem (FEP). The next underway phase of the carrier’s training will integrate other ships as Truman continues deployment work-ups.
The 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 Marine Expeditionary Unit, continue to support the humanitarian relief efforts for Hurricanes Irma and Maria in Puerto Rico.
Hospital ship USNS Comfort (T-AH-20) arrived off Puerto Rico on Tuesday, Oct. 3.
“Comfort’s primary mission is to provide an afloat, mobile, acute surgical medical facility to the U.S. military that is flexible, capable, and uniquely adaptable to support expeditionary warfare,” according to Military Sealift Command.
“Comfort’s secondary mission is to provide full hospital services to support U.S. disaster relief and humanitarian operations worldwide.”
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.
