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.
Operators
Taiwan (Republic of China): Taiwan's principal fighter type · United States and the Taiwan Strait: Supplier under Taiwan Relations Act arms sales
Battlefield role
Air defence and air policing, including the routine interception activity that constitutes Taiwan's day-to-day response to reported PLA air presence, plus anti-ship and standoff strike roles in a defensive concept.
Strengths
The V-standard upgrade brought a modern active electronically scanned array radar and current-generation missiles across most of the fleet, giving Taiwan a broadly homogeneous and capable fighter force. Deep US support, training and spares ecosystem behind it.
Limitations
A fourth-generation airframe facing an opponent operating low-observable types in growing numbers. More fundamentally, aircraft require runways, and an air force operating from a small island has inherent basing constraints — the principal argument made by advocates of shifting investment toward ground-based and mobile systems. Sustained interception activity imposes airframe hours and crew fatigue costs that fall asymmetrically on the smaller force.
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.

Documented conflict use
Taiwan's air force publicly reports responding to PLA activity around the island on a near-daily basis. Delivery of newly built Block 70 aircraft and the upgrade programme for existing airframes have both been publicly reported, with schedule slippage acknowledged. No basing, dispersal, readiness or sortie-rate information is published in this module.
