Identity provenance
Service ensign: Flag of the Republic of China Air Force — carried by ROC Air Force, not issued to this record. The Air Force flag — a sky-blue field charged with the service's winged badge around the white sun. Public domain on Commons in its own right; the ROC Ministry of National Defence is recorded as the author of the original design. LEGIBILITY, STATED: the badge is a detailed device and at the 18x12px the formations index renders a mark at it resolves to a pale form on sky blue. It was kept because the FIELD COLOUR carries the identity at that size and the badge resolves properly at the 38x26 and 40x40 the Atlas card and masthead use — the same test the 1MB Iranian service flags failed and were refused on.

In brief
The command that holds Taiwan's ground-based air and missile defence — the layer beneath the fighters, and the one the module's missile-defence analysis actually refers to.

- Notable history
- One of the four commands the Air Force Command Headquarters publishes as its components, and the organisational answer to a question the module raises constantly: when analysis says "Taiwan's layered air and missile defence", this is the thing it is naming. The command consolidated air-defence artillery and surface-to-air missile functions that had previously been divided between services, which is why a capability most militaries hold in the army sits in the air force here. It operates both imported and indigenous layers — the Patriot family alongside the domestically developed Tien Kung series — and the warning picture that makes either useful depends on a long-range early-warning radar that has been operational since 2013 and publicly credited with detecting a ballistic launch in July 2026.
- Strengths
- A genuinely layered system combining imported and indigenous interceptors, fed by long-range early warning, under one command rather than split across services. The indigenous layer matters disproportionately: it is the part of the inventory whose expansion does not require a foreign export decision.
- Limitations
- Interceptor inventories are finite and the opposing missile inventory is not comparably constrained; every serious published treatment of this problem is a magazine-depth argument, and none of the figures involved are published by this module. Early warning from a small island is measured in minutes, and the single long-range radar that provides it is the most obvious first-night target in every scenario written about it — which is a structural observation made in public commentary, not an assessment made here. No site locations, battery counts, coverage, interceptor numbers or readiness are recorded anywhere in this module.
Key events
Special defence budget passed at NT$780bn, well below the request
After months of gridlock, Taiwan's Legislative Yuan passes a multi-year special defence budget of NT$780bn — substantially more than the opposition's initial NT$380bn counter-proposal, and roughly 38% below the NT$1.25tn the executive had sought to fund US procurement, domestic industry and an integrated air-defence programme.
