In the Indian Ocean

The Makin Island Amphibious Ready Group (ARG) with the 15th Marine Expeditionary Unit (MEU) continues to operate off Somalia. The Makin Island ARG and 15th MEU are providing operational and air support to Joint Task Force – Quartz and Operation Octave Quartz. Octave Quartz is the U.S. mission to reposition 700 troops from Somalia to other parts of the region.

USS Hershel “Woody” Williams (ESB-4) is also participating in the operation. Commissioned on March 7, Williams is a Lewis B. Puller-class expeditionary sea base and is based in Souda Bay, Greece.

The ARG includes amphibious assault ship USS Makin Island (LHD-8) and amphibious transport docks USS Somerset (LPD-25) and USS San Diego (LPD-22). The 15th MEU consists of the Command Element; the Aviation Combat Element comprised of Marine Medium Tiltrotor Squadron 164 (Reinforced); the Ground Combat Element comprised of Battalion Landing Team 1/4; and the Logistics Combat Element comprised of Combat Logistics Battalion 15. Other units include Helicopter Sea Combat Squadron 23, Helicopter Maritime Strike Squadron 49, Tactical Air Control Squadron 11, Beach Master Unit 1, and Fleet Surgical Team 1 from San Diego and Assault Craft Unit 5 from Camp Pendleton, Calif.

In the Persian Gulf

On Dec. 21, U.S. 5th Fleet announced that guided-missile submarine USS Georgia (SSBN-729) entered the Persian Gulf.

“SSGNs are one of the most versatile platforms in the fleet, equipped with superior communications capabilities and the ability to carry up to 154 Tomahawk land-attack cruise missiles. The platform can also be configured to host up to 66 Special Operations Forces,” reads the statement from 5th Fleet.

Announcing an SSGN operating in the Persian Gulf is a rare move for the Navy, and this public disclosure is intended as a message both to Iran and U.S. regional allies, USNI News previously reported.

The submarine made a port call at Bahrain from Dec. 24 to 27, according to photos released by the Navy.

Last week, USNI News reported on the growing trend of merchant ship harassment by Iran and militant groups backed by Tehran.

“Iran’s armed seizure of a South Korean tanker, the Hankuk Chemi, on Jan. 4 adds to the list of incidents where civilian ships have been targeted in the Middle East. Iranian forces boarded the vessel in the Strait of Hormuz as it was leaving the Persian Gulf, which comes less than a week after another tanker, Pola, was attacked with a limpet mine on Dec. 31,” reported USNI News.

On Sunday, it was reported the Trump administration has decided to designate Yemen’s Houthi rebels as a foreign terrorist organization for, among other things, attacks on commercial shipping.

In addition to these major formations, not shown are thousands of others serving in submarines, individual surface ships, aircraft squadrons, SEALs, Special Purpose Marine Air-Ground Task Forces, Seabees, Coast Guard cutters, EOD Mobile Units, and more serving throughout the globe.
