PLA Activity — Jul 21–27

Weekly total: ~103 sorties across 7 days. Median line crossed every day. Jul 25–26 alone: ~59 sorties.

Daily MND figures (sorties / PLAN vessels / official ships — crossings noted):

  • Jul 21: 4 sorties / 6 PLAN / 5 official — all 4 crossed median; N, central, SE ADIZ. First confirmed PLA helicopter median line crossing — loitered in Taiwan's restricted zone R9 ~9.5 hours (10:20–19:40 local). UAV also crossed same day.
  • Jul 22: 8 sorties / 8 PLAN / 2 official — helicopter crossing confirmed in follow-on MND report.
  • Jul 23: 21 sorties / 6 PLAN / 2 official — 20/21 crossed median; N and SW ADIZ. PLA satellite launch from Xichang Satellite Launch Center pre-warned by MND; overflew SW ADIZ.
  • Jul 24: 8 sorties / 6 PLAN / 4 official — 6/8 crossed median; N, SW, E ADIZ.
  • Jul 25: 29 sorties / 6 PLAN / 5 official — 17/29 crossed median; N, central, SW ADIZ.
  • Jul 26: 30 sorties / 7 PLAN / 5 official — 26/30 crossed median; all four ADIZ quadrants. No confirmed triggering diplomatic event in open sources.
  • Jul 27: 3–4 sorties / 7 PLAN / 4 official — 1 crossing; SW ADIZ. Sharp one-day pullback.

New Gray-Zone Template: Helicopter Crossing

Jul 21 helicopter crossing is the first publicly confirmed PLA rotary-wing median line transit. The helicopter + UAV combination introduces a lower-cost, higher-persistence harassment vector with 9.5-hour loiter capability inside Taiwan's restricted zone. Two new gray-zone mechanisms introduced simultaneously.

SCMP analysis (Jul 22) assessed the tactic as rehearsing additional control mechanisms short of kinetic action. Taipei Times reported the helicopter as a new template not previously employed, distinct from fixed-wing ADIZ incursions. Sustained recurrence would constitute escalation of the gray-zone pattern established since the Jul 4 CCG east-Taiwan institutionalization.

CCG Status

No new CCG incidents reported Jul 21–27. CCGS Xiushan standing patrol ~54nm east of Hualien continues. No additional vessels or rotations confirmed this week. Taiwan CGA two-vessel shadow maintained.

Arms Sale — Status Downgrade

$14B package (PAC-3, NASAMS, HIMARS, M109A7): STATUS PAUSED. Acting Navy Secretary Hung Cao informed Congress May 22 the sale is on hold to preserve munitions depleted by Operation Epic Fury (US strikes on Iran, begun Feb 28, 2026). This is a downgrade from "under executive review." No resumption announcement as of Jul 27.

Component-level items on separate tracks (unchanged):

  • PAC-3 MSE (102 units): deliveries began Jan 2026 under prior contract; separate from the $14B package.
  • NASAMS: approved FMS contract; completion projected 2031.
  • HIMARS (18 launchers + 20 ATACMS + 864 GMLRS): ahead of schedule — expected Q4 2026 (prev. 2027).

Diplomatic Developments

  • Jul 23: Trump confirmed Xi Jinping White House visit Sep 24, 2026 — AI governance named primary agenda item. At May 2026 Beijing summit, Xi warned Taiwan mishandling could cause "clashes and even conflicts."
  • PORCUPINE Act (H.R.7146): No House floor vote. HFAC 45-0 (May 13) status unchanged; no scheduling announced.
  • PRC Ethnic Unity Law: Entered force Jul 1, 2026. Taiwan's national security apparatus warns it extends extraterritorial sanctions authority over overseas dissidents, Taiwanese citizens, and foreign researchers.
  • Taiwan drone budget — opposition cuts: KMT proposed freezing NT$44.2B (~$1.37B) Executive Yuan drone industry plan (Jul 26 audit prompted). TPP proposed cutting NT$200M from NT$623M MOOE drone training allocation (Jul 27). May 2026 opposition cuts left only FMS channels intact; domestic procurement blocked.

Polymarket & Probability Assessment

Polymarket (approx. Jul 25, 2026):
Invasion before Jan 1, 2027: 4.2% (~$39M vol) — ↑ from 3.75%
Military clash before 2027: ~7% — ↓ from ~12.5% (note: market definitions may differ between periods)
Invasion by Dec 31, 2027: ~14.5% — ↑ from ~12%

Assessed invasion probability — unchanged from Jul 20:

  • 1 month: 1–2% — helicopter crossing is a new tactic, not an invasion precursor; Sep 24 Xi–Trump summit imposes near-term de-escalation constraint.
  • 6 months: 5–7% — Xi–Trump summit diplomacy constrains risk through Q4 2026.
  • 1 year: 10–13% — unchanged.
  • 5 years: 18–24% — quarantine/blockade scenarios weighted 2–3× landing invasion within this figure.
Warning tier: BASELINE. Jul 21 helicopter crossing is a new gray-zone template; sustained recurrence would trigger WATCH. The Jul 26 30-sortie surge occurred without a confirmed exercise designation but falls short of the ≥20-sortie / ≥3-consecutive-day threshold for tier escalation. Tier reviewed per-week.
