Taiwan Strait: Deterrence, Pressure and Strategic Competition
A Watch question is not a forecast. It names the evidence that would change an assessment and records what each review found — including the reviews that found nothing moved.
Where it stands
Standing assessment
Current assessment
Moderate confidenceAs of
Held in public in Washington; enacted as law, not money, in Taipei.
On 23 September 2026 the Secretary of State said Taiwan arms sales remain under review, citing US industrial capacity; a senators' letter reports $300m of military financing unobligated, $1bn of cooperation funds not set aside and a $14bn sale withheld. The backlog stood at $29.72bn in mid-2026. On 27 August the legislature replaced the Cabinet's drone act with a NT$240bn six-year funding principle through annual budgets; the 2027 and supplementary budgets have had no committee action. The first two F-16 Block 70s of the 2019 case arrived on 2 October.
Latest reviewNo material change3 without change
No second F-16 Block 70 delivery on the ministry's Chinese release list to 23 October, and no US notification or decision on the held package found. A newspaper account from an unnamed defence official of force restructuring is not a decision. The check of US notifications was limited.

What would change the assessment2 assessment-change conditions · qualitative, as the record states them
A backlog figure that falls with named deliveries across two consecutive reports, together with an enacted 2027 budget whose domestic uncrewed-systems line is restored
Assessment effectmoves the question from execution to fielding.
The outstanding package refused or deferred publicly, or the 2027 budget cut on the pattern of May 2026
Assessment effectmoves the constraint from industrial to political on both sides at once.
Observables6 named · 2 met · “met” describes evidence, not success
01Test
The notified-but-undelivered backlog figure
The published aggregate, read against the previous figure, with named case milestones rather than announcement values.
02RecordedMet
Named case milestones — contract, delivery, fielding
A specific case moving between the five states, reported by either government. Announcement values are not milestones.
Recorded by The first new F-16s reached Taiwan, which is a case arriving at delivery and not yet a capability
03Test
A decision on the package Taipei has asked to be approved
Approval, refusal or an explicit public deferral — a stated decision to postpone, with or without a date. Any of the three is a finding. A statement that the package is under review is not a deferral: it is evidence of friction, recorded as movement.
04Test
Enactment of the 2027 defence budget and the supplementary budget
Committee action, scheduling decision or party position change in the Legislative Yuan on the two appropriations before it.
05RecordedMet
The NT$210bn drone procurement bill leaving committee
The bill's passage, amendment or lapse, and whether uncrewed-systems funding reappears through appropriation instead.
Recorded by Taiwan's drone bill was settled a month ago, and what was enacted is a funding principle, not money
06Test
Disbursement and delivery against enacted appropriations
Enactment, then disbursement, then delivery — reported at case level for the domestic programmes the special budget kept.
2 of 6 tests have been recorded as met. “Met” states that the evidence appeared, not that the development was favourable.
Review ledger14 entries · opened · newest first, each tied to the review that made it
No material change
No second F-16 Block 70 delivery on the ministry's Chinese release list to 23 October, and no US notification or decision on the held package found. A newspaper account from an unnamed defence official of force restructuring is not a decision. The check of US notifications was limited.
Weekly Brief Taiwan Strait developments — 25 October 2026
No material change
No second F-16 Block 70 delivery on the ministry's release list or in reporting to 17 October; the minister told the legislature on 12 October that six of 66 had passed factory acceptance and hoped for more deliveries this month. No US notification or decision on the held package found; the US arms-sales agency's site could not be read.
Weekly Brief Taiwan Strait developments — 18 October 2026
No material change
No second F-16 delivery and no US decision on the outstanding package. The TPP chairman said on 10 October that committee review of the 2027 budget and the supplementary budget had not begun.
Weekly Brief Taiwan Strait developments — 11 October 2026
Observable met
A named case reached delivery on a government's report: the Air Force said the first two F-16 Block 70s of the 2019 sale landed on 2 October. It is delivery, not fielding; acceptance and conversion training follow. The $14bn package stays under review, 21 Democratic senators urged delivery, and no budget committee action was found.

Assessment changed
The US side moved from an unexplained wait to a stated deferral. The Secretary of State said on 23 September that sales remain under review and named US industrial capacity; a senators' letter, as reported, adds unobligated financing and unallocated cooperation funds to the withheld $14bn sale. The leaders' meeting of 24 September passed without an approval or a notification. Read with the drone act, both sides of the question now carry a stated constraint rather than a pending decision.
Brief item Washington named a reason for the wait and made no decision, which is a constraint stated rather than a policy changedEvent A $14bn package is held back as a "negotiating chip"Reviewed in 2026-09-27
Observable met
Found late and recorded now. The bill's fate was settled on 27 August, when the legislature rejected the Cabinet's NT$210bn special act and passed the opposition parties' own act — NT$240bn over six years, NT$40bn a year, as a funding principle through annual budgets — which the president promulgated on 11 September. The briefs of 30 August, 6 and 20 September described the bill as still in committee; they stand as published. The second half of the observable, funding through appropriation, is unmet: the act appropriates nothing.

Movement observed
Evidence on the fielding end rather than the notification end. HIMARS launchers and ALTIUS 600M loitering munitions were fired at Jiupeng in the exercise of 16 to 18 September, which is delivery and fielding observed rather than described. No backlog figure was published, no named case reached a new milestone, no outstanding package decision was announced and no disbursement figure appeared. The drone-bill observable is worth restating here: the munitions exercised are of the class the legislature cut from the special budget in May, and nothing in the window restored that funding.

Movement observed
No new signature, delivery or public decision on the outstanding cases was identified, and no committee action was recorded on the supplementary budget. New evidence bears on the delivery side from an unexpected direction: Japanese reporting on 12 September, sourced to unnamed officials, says Beijing has signalled it could cancel the leaders’ meeting scheduled in Washington for 24 September if Washington approves new sales. If that linkage is real it makes an approval date a diplomatic decision rather than a procedural one; it rests on one outlet and anonymous sourcing, and neither government has confirmed it.
Brief item A reported linkage between a summit and an arms approval, which would change how transfers are timedReviewed in 2026-09-13
Movement observed
A supplementary budget funds uncrewed systems through appropriation rather than through the drone bill, and does not resolve it; the 2027 proposal is unaddressed in its third window; no US decision on the outstanding package.

No material change
No committee action, scheduling decision or party position change on the 2027 proposal; the drone bill still in committee; no new US signature, delivery or decision, and the package Taipei has asked to be approved remains outstanding.
