Notable history
Established on 28 April 2018 in the reorganisation that moved the Coast Guard Administration under the newly created Ocean Affairs Council, the Fleet Branch consolidated the CGA's sea-going forces into one organisation separate from the regional coastal branches. It is the operational centre of the module's grey-zone lane: when Taiwanese authorities report that coast guard vessels shadowed, warned or expelled Chinese state vessels, these are the ships. The branch is also the vehicle for the CGA's expansion — a 2018 programme targeting a large new-build patrol fleet by 2027, and a further special-budget proposal for around forty additional domestically built vessels — which is the clearest instance in this module of a civilian agency being funded on a defence rationale.
Strengths
Provides a proportionate, non-military instrument for non-military pressure, which is the correct answer to a coast guard challenge and the one that avoids converting a law-enforcement encounter into a military one. Its newer larger hulls extend the endurance needed to match sustained presence, and its vessels exercised the wartime transfer arrangement with the navy for the first time inside Han Kuang 42 in August 2026.
Limitations
Outmatched in tonnage and hull numbers by its Chinese counterpart, and structurally required to respond to sustained presence without either conceding jurisdiction or escalating — a position that gets harder the longer it holds. Shipbuilding programmes are announced in vessel counts and delivered over years, and this module publishes no fleet strength, no vessel dispositions, no patrol patterns and no readiness.
Lineage & institutional history
Key events
A coast guard task group is rotated east of Taiwan
Until June 2026 China Coast Guard activity in waters east of Taiwan had occurred only within announced military exercises. In June a task group led by the cutter Daishan began patrols there, described by the coast guard as law enforcement including vessel inspection, fishery protection and rescue. On 4 July a second task group led by the cutter Xiushan replaced it and continued the patrols, with the service stating it would strengthen law enforcement in what it called China's jurisdictional waters. Taiwan's authorities reject the characterisation. The rotation drew statements of concern from regional governments.
Han Kuang 42 closes after ten days
Taiwan's 42nd Han Kuang exercise concluded on 14 August 2026 at Bo'ai Camp in Taipei, ten days after it began on 5 August, with the chief of the general staff, service chiefs and regional commanders present. Defence Minister Wellington Koo said the exercise had run with fully operational command centres at every level for the first time and had continued the unscripted format, with units responding to developing orders rather than a rehearsed sequence; he praised participating troops and told officers to address the problems the exercise had identified. Reporting describes it as Taiwan's largest military exercise since 1984, mobilising more than 20,000 reservists. Its components across the ten days included the two mobile-network throttling windows recorded separately here, dispersal of weapons production and mobilisation of civilian manufacturing, urban resilience training run inside the military exercise, and the first joint navy–coast guard anti-blockade drill. China's defence ministry issued its first official comment on the exercise on its final day, spokesperson Chen Xi calling it a posturing, wasteful charade and accusing the governing party of stoking war panic.
