In an unannounced move showcasing growing maritime cooperation, the U.S. and Taiwan conducted impromptu military exercises in the West Pacific. This development comes amid rising tensions between Taiwan and China, ahead of the inauguration of Taiwan's president-elect, Lai Ching-te. According to unnamed sources cited by Reuters, the drills took place during routine naval encounters.
One source mentioned the involvement of “multiple military assets,” while another highlighted that these exercises were unofficially termed “unplanned sea encounters,” implying a tacit agreement that these drills were coincidental rather than premeditated.
These exercises occurred between a series of scheduled high-profile drills. In mid-April, the U.S. conducted a trilateral exercise with Japanese Maritime Self Defense Force (JMSDF) and Republic of Korea Navy (ROKN) vessels, focusing on interoperability and warfighting capabilities. Shortly after, the Balikatan 24 exercise in the Philippines involved the U.S., Philippine, Australian, and French forces, concentrating on counter-landing operations and maritime domain awareness.
During the unplanned U.S.-Taiwan drills, around six ships, including supply vessels and frigates, engaged in basic communications, resupply operations, and joint anti-submarine warfare (ASW) exercises. These drills are critical for ensuring operational compatibility between the two navies in emergencies, involving tactical maneuvers and underwater target searches.
Taiwan's Ministry of National Defense spokesperson, Major General Sun Li-fang, stated that the exercises adhered to the Code for Unplanned Encounters at Sea (CUES), which manages interactions between different militaries at sea. This protocol was previously utilized in 2016 during an encounter between the USS Chafee and three ROCN ships.
The disclosure of these exercises follows Taiwanese Chief of General Staff Admiral Mei Chia-shu’s visit to the U.S. Indo-Pacific Command (USINDOPACOM) change of command ceremony in Hawaii in early May. Shortly after, China conducted significant military exercises around Taiwan, labeled “Joint Sword-2024A,” which involved near-encirclement maneuvers similar to those after Nancy Pelosi's visit in 2022.
In late May, the U.S. began Tiger Strike 2024 with Malaysia, focusing on amphibious warfare and multi-domain awareness. Early June saw the announcement of the “Freedom Edge” exercise, a first-time trilateral drill involving the U.S., Japan, and South Korea.
These high-profile activities in the West Pacific lead up to the Rim of the Pacific 2024 (RIMPAC 24) exercises, scheduled from June 28 to August 2, involving 29 nations, 40 surface ships, 3 submarines, 14 national land forces, over 150 aircraft, and more than 25,000 personnel. The Italian carrier Cavour and a French Navy FREMM air defense frigate will also participate.
