CARAT/MAREX Sri Lanka took place in Colombo, at Sri Lanka Navy (SLN) bases in Trincomalee and Mullikullam, and in the Laccadive Sea, Jan. 19-26. The exercise focused on increasing proficiency in humanitarian assistance, disaster relief (HADR), and maritime security capabilities.

“From our maritime roots comes a reliance on the sea for our prosperity, and a shared vision of a world in which all sovereign states can peacefully interact with each other and participate in a rules-based order,” said Rear Adm. Joaquin J. Martinez de Pinillos, vice commander, U.S. 7th Fleet. “This exercise, and the efforts of all who helped bring it to life, are a testament to the United States and Sri Lanka’s commitment to achieving that shared vision.”

SLN offshore patrol vessels SLNS Gajabahu (P 626) and SLNS Vijayabahu (P 627) met amphibious transport dock USS Anchorage (LPD 23), with embarked 13th Marine Expeditionary Unit (MEU), at sea. This year’s exercise included participants from the Japan Maritime Self-Defense Force (JMSDF) and Maldives National Defence Force, as well as the Sri Lanka Air Force.

For the HADR training, two USN landing craft transferred troops, supplies, and vehicles ashore to a beach area of Mullikulam. The subsequent exercises tested and improved the partners’ ability to coordinate and communicate with one another in a simulated disaster environment.

“I thank all participants for their commitment and enthusiasm throughout the exercise and really appreciate all the hard work and level of professionalism demonstrated throughout the last few days in order to conduct this exercise beyond expectations,” said Commander of the SLN Vice Adm. Priyantha Perera. “I hope this good relationship among Sri Lanka, United States, Japan and Maldives will continue progressively in the future to cherish the strong relationships that we are maintaining to effectively address common interests.”

Additional exercises conducted at sea included divisional tactics, visit, board, search, and seizure (VBSS), replenishment-at-sea approaches, and reconnaissance and gunnery exercises. Helicopters aboard Anchorage successfully carried out VBSS exercises, embarkation, and disembarkation of personnel and material on the decks of the SLN ships involved in the sea phase.

Shore phase highlights included a Women, Peace and Security roundtable with members of the Sri Lanka and U.S. militaries hosted by U.S. Ambassador to Sri Lanka Julie Chung, public performances between both countries’ navy bands, a sports day, and a series of community service activities.

"During this fifth iteration of CARAT/MAREX Sri Lanka, our two countries were able to conduct knowledge exchanges with follow-on practical application,” said Lt. Col. Jared Reddinger, commanding officer, Battalion Landing Team 2/4, 13th MEU. “In doing so, we sharpened our skills, improved interoperability, and worked together towards a mutual vision for a free and open Indo-Pacific.”

The shore phase training consisted of subject matter expert exchanges on issues like diving and underwater construction, medical support, and maritime domain awareness. Additional participating U.S. assets included a P-8A Poseidon and personnel from U.S. 7th Fleet, Commander, Task Force (CTF) 72, CTF 73, CTF 76/3, Destroyer Squadron (DESRON) 7, and Amphibious Squadron 7.

“Both on land and at sea, the success of the CARAT exercise is a testament to the depth of the U.S. – Sri Lanka bilateral relationship, which is 75 years strong,” said Ambassador Chung. “We look forward to building on this partnership to continue to advance the security and prosperity of the region.”
