The recordWhat this system is, where it comes from, who operates it and which of Vigil’s modules it is relevant to — with the evidence each of those rests on.
Record
Conflict relevance
This is the catalogue's single record for this system. It is relevant to the module below; each module's Force Atlas shows how it is used there.
Battlefield role
Presence and asserted law-enforcement jurisdiction. Their function is categorical rather than kinetic: a white hull conducting "inspections" is extremely difficult to answer, because a military response is disproportionate and no response concedes the point.
Strengths
Very large hulls with endurance for sustained presence, backed by the world's largest coast guard. Their real advantage is legal and political framing rather than material: they generate pressure while remaining below any threshold that would justify escalation. The framing rests on published authority — the 2021 Coast Guard Law asserts enforcement in undefined "maritime areas under Chinese jurisdiction", and administrative procedures in force from June 2024 set out boarding, inspection and detention of foreign vessels within that space. Endurance matters because it converts presence into routine: a task group that can be relieved on station, as happened east of Taiwan on 4 July 2026, sustains a claim that an episodic patrol does not.
Limitations
The strategy depends on ambiguity holding, and the ambiguity is doing more work than the hulls are. Incidents involving injury or death — as in the February 2024 Kinmen case that preceded the current patrol pattern — carry escalation risk the law-enforcement framing cannot contain. Visible integration into military operations cuts the same way: coast guard vessels operating inside the Justice Mission-2025 joint exercise made the civil–military distinction harder to maintain, which is a cost to the instrument as well as a demonstration of reach. Against a warship these are lightly armed vessels, and their value would fall sharply in any situation where the law-enforcement framing had already been abandoned.
Campaign relevance
Derived: a participant organisation in these campaigns carries a typed equipment association with this system. That is not the same as documented use of the system in the campaign itself.

- Coercive maritime interdiction — quarantine to blockade Assessed contingency
via China Coast Guard (Documented, moderate confidence)
Documented conflict use
Recurring patrols in waters around Kinmen since February 2024, publicly reported by both Taiwanese authorities and Chinese official statements, with Taiwan's coast guard recording scores of incursions in the following year. Participation in the Justice Mission-2025 joint exercise of 29–31 December 2025, with 13 coast guard vessels detected on the first day and 15 on the second. Standing patrols east of Taiwan from June 2026, where a task group led by the Daishan was relieved by one led by the Xiushan on 4 July. Vigil records that these patrols occur and publishes no routes, schedules, patterns or vessel dispositions.

Related 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.
