ROC Air Force
Taiwan's air arm — the service that meets near-daily reported PLA air activity and operates the island's layered air and missile defences.
Broad area of activity
Taiwan's airspace and air defence identification zone
Notable history
Modernised substantially in the 1990s with the near-simultaneous acquisition of F-16s, Mirage 2000-5s and the indigenous Ching-kuo fighter — a three-type fleet that remains its structure today, now upgraded rather than replaced. Since the mid-2010s its most demanding routine task has not been combat but attrition management: responding to sustained PLA air activity that erodes airframe hours, fatigues crews and consumes readiness without a shot being fired.
Strengths
An upgraded and increasingly homogeneous fighter fleet with modern radar and missiles, extensive layered ground-based air and missile defence, and the accumulated experience of managing constant interception activity.
Limitations
Faces a far larger opposing air force; sustained grey-zone activity imposes a real and asymmetric maintenance and fatigue burden; and an air force operating from a small island has inherent basing constraints that drive its investment in dispersal, hardening and mobile systems. Vigil publishes no basing, dispersal or readiness detail.
