PLA Surges to 17 Sorties + 7 PLAN Vessels on April 11 — 15 of 17 Cross Median Line Into Northern + SW ADIZ; Highest Single-Day Count Since March 29

Taiwan's Ministry of National Defense reported (as of 0600 local time April 11, 2026) detecting 17 PLA aircraft sorties alongside 7 PLAN vessels and 1 official ship operating around Taiwan — with 15 of the 17 sorties crossing the Taiwan Strait median line and entering Taiwan's northern and southwestern ADIZ sectors. Taiwan deployed CAP aircraft, naval ships, and coastal missile systems in response. The April 11 count of 17 sorties is the highest single-day total since the late-March spike peak of 19 sorties (March 29, 2026), and represents a dramatic escalation from 6 sorties on April 9 and 7 sorties on April 10. The surge comes the day after the historic Xi Jinping–KMT Chairwoman Cheng Li-wun summit at the Great Hall of the People (April 10) — a pattern consistent with PLA doctrine of signaling that political dialogue does not constrain military pressure. The multi-sector northern and southwestern ADIZ crossings (15 of 17 sorties penetrating the median line) represent a sustained combined pressure signal as Cheng's visit continues on Day 5 in Beijing. The 7-vessel PLAN count is slightly down from 8–9 vessels during April 7–9, but the sharp air activity surge to 17 sorties is the dominant signal of the day. Interpretation: PLA used the post-summit window to reassert coercive deterrence posture, preventing any perception that the Xi-KMT dialogue represents a softening of military pressure against Taiwan's current DPP government.
