China Conducts Three-Day Naval Exercise Around Taiwan Strait, Deploying Carrier Battle Group

Background

China has conducted periodic large-scale military exercises around Taiwan since the 1990s, most notably during the Third Taiwan Strait Crisis of 1995 to 1996, when PLA missile tests bracketing the island prompted the United States to deploy two carrier battle groups to the region. Since 2022, following the visit of US House Speaker Nancy Pelosi to Taipei, China has conducted increasingly large and complex exercises that the PLA has described as 'Joint Sword' operations and which have included realistic rehearsals of blockade, strike, and amphibious assault elements. The pattern of exercises has grown in scale and frequency, reflecting both the PLA's increasing capabilities and Beijing's stated goal of using military exercises as a form of political pressure on Taiwanese authorities and as a deterrence signal to the United States. The Fujian aircraft carrier, China's third and most capable carrier, was commissioned in 2024 and represents a significant advancement in PLA Navy power projection capability. Unlike China's earlier carriers, the Liaoning and Shandong, which use ski-jump launch systems, the Fujian features electromagnetic launch catapults similar to the US Navy's EMALS system, enabling it to operate a wider range of aircraft at higher sortie rates. The carrier's deployment in the Taiwan Strait exercise signals China's intention to use its most advanced assets in exercises calibrated to demonstrate capability and resolve without triggering the specific tripwires that would activate US security commitments to Taiwan.

Exercise Details and Military Assessment

The October 12 to 14, 2026 exercise was announced in advance by the Eastern Theater Command of the PLA through a NOTAM, a notice to airmen and mariners restricting navigation and overflight in designated areas of the Taiwan Strait and western Pacific. The designated exercise areas included sea spaces east of the Taiwan median line that China has previously characterised as outside its claimed territorial waters, and airspace directly adjacent to Taiwan's Air Defence Identification Zone. The Fujian carrier battle group operated in the southern Taiwan Strait with its accompanying cruiser, destroyer, and replenishment vessels, while submarine assets were assessed by US and Japanese intelligence to have operated in the Philippine Sea east of Taiwan. Surface combatants from the Northern and Southern Theater Commands also participated, creating a multi-direction exercise that Taiwan's military acknowledged required it to monitor approach vectors from north, south, and west simultaneously. Anti-ship missile launch events on October 13, assessed by US Indo-Pacific Command as tests of the YJ-21 hypersonic anti-ship missile, were conducted against target vessels in the exercise area. Taiwan's Ministry of National Defense stated that 103 PLA aircraft and 27 ships were detected within or adjacent to Taiwan's ADIZ and waters over the three days, the highest cumulative count in any single exercise since August 2022. The US response included the repositioning of destroyer squadrons from the 7th Fleet toward the Philippine Sea and a statement from the National Security Council characterising the exercise as 'destabilising and provocative' while stopping short of categorising it as a change in the status quo.

• YJ-21 hypersonic anti-ship missile tests assessed on October 13.
• 103 PLA aircraft and 27 ships detected within or adjacent to Taiwan ADIZ over three days.
• US repositioned 7th Fleet destroyer squadrons to Philippine Sea in response.

Political Context and Implications

The timing of the October 2026 exercise is linked by regional analysts to Taiwan's upcoming local elections in November 2026, in which the ruling Democratic Progressive Party faces challenges that could reshape the island's domestic political balance. Beijing has historically used military pressure ahead of Taiwanese elections in an attempt to influence voter behaviour, though the evidence for the effectiveness of this approach is mixed, as exercises in 2022 and 2024 did not produce the electoral outcomes China sought. The exercise also follows a period of elevated Taiwan Strait tensions related to Taiwanese government announcements about expanding domestically produced submarine capacity and upgrading the island's air defences with additional Patriot PAC-3 MSE batteries, both of which Beijing described as 'provocations'. Japan's response was particularly significant, with the Japanese Maritime Self-Defense Force publicly disclosing its own anti-submarine warfare exercise conducted simultaneously in the Philippine Sea and the Japanese government issuing a statement describing the PLA exercise as 'a serious security concern for Japan and the region'. The Philippines government called for restraint while expressing concern about freedom of navigation in waters adjacent to its northern islands. The exercise provides data for PLA planners on the coordination capabilities of the multi-carrier and multi-theater formation, and for US and allied planners on the specific sequences and capabilities being rehearsed. Military analysts note that the exercise's simulation of blockade elements suggests continued PLA development of options short of full-scale invasion, consistent with a strategy of maintaining coercive pressure on Taiwan while preserving decision space for Chinese political leadership.
