U.S., Thailand conduct anti-submarine exercise in Andaman Sea

06 April 2019

From MC1 Greg Johnson, CTF 73 Public Affairs

The U.S. Navy and Royal Thai Navy began the 8th iteration of exercise Guardian Sea with a ceremony aboard the frigate HTMS Bhumibol Adulyadej, April 7.

ANDAMAN SEA - The U.S. Navy and Royal Thai Navy (RTN) began the 8th iteration of exercise Guardian Sea at the opening ceremony aboard the RTN frigate HTMS Bhumibol Adulyadej in the Andaman Sea, April 7.

A U.S. Navy Los Angeles-class fast attack submarine and underway replenishment oiler along with two RTN frigates, a corvette and a Sea Hawk helicopter will participate in over a dozen evolutions, designed to incorporate shared techniques in real-world at-sea environments.

“The U.S. and Royal Thai Navy continues to work closely in anti-submarine warfare towards building upon our already-established combined capabilities,” said Capt. Matt Jerbi, commodore of Destroyer Squadron 7. “Guardian Sea 2019 is a premier exercise that demonstrates our commitment to each other in ensuring that we are ready to counter any threats together, both above and underwater.”

Guardian Sea 2019 marks the first time the RTN will deploy a towed array. The towed array sonar aboard HTMS Bhumibol Adulyadej, used for detecting undersea contacts including submarines, demonstrates the increasing complexity and sophistication of the exercise with more advanced training objectives.

“This is the kind of training our Sailors practice for at home and implement at sea,” said Rear Adm. Jimmy Pitts, commander, Submarine Group Seven. “We’re excited for the opportunity to showcase the skills our crews have honed and sharing our best practices with our Thai Navy counterparts.”

The exercise is organized in two phases with a shore phase consisting of subject matter expert exchanges across every aspect of anti-submarine warfare and a subsequent sea phase that culminates with tracking a submarine while protecting a surface ship in a “free-play” event.

"Our ability to conduct anti-submarine exercises while implementing lessons learned, advanced tactics and procedures into each new iteration of Guardian Sea is a testament to the professionalism and interoperability of both U.S. Navy and Royal Thai Navy forces," said Lt. Josh Northcutt, U.S. Navy Guardian Sea lead planner. "Having been part of the team during Guardian Sea 2018, I look forward to building upon shared knowledge from last year and reconnecting with our friends from the Royal Thai Navy."

Guardian Sea builds upon other engagements and exercises with Thailand to include Cooperation Afloat Readiness and Training (CARAT), now in it’s 25th iteration; Pacific Partnership, the largest annual multilateral humanitarian assistance and disaster relief preparedness mission; Southeast Asia Cooperation and Training (SEACAT) involving more than a dozen partner nations; and Cobra Gold, Indo-Pacific's largest multinational exercise. These engagements serve to enhance information sharing and coordination, build mutual warfighting capability and support long-term regional cooperation.
