PLA Surges to 15 Sorties on Navy 77th Anniversary — 14 of 15 Enter SW ADIZ; Re-Escalation from April 22 Pullback

Taiwan's Ministry of National Defense reported 15 PLA aircraft sorties and 5 PLAN vessels plus 1 official ship operating around Taiwan as of 06:00 local time on April 23, 2026 — a significant re-escalation from the 6-sortie pullback of April 22. Of the 15 sorties, 14 entered Taiwan's southwestern ADIZ — a concentrated southwestern penetration pattern. The spike coincides directly with the PLA Navy's 77th founding anniversary (founded April 23, 1949), a date the PLA routinely uses for symbolic military signaling. The April 23 jump to 15 sorties disrupts the expected post-spike de-escalation arc: Liaoning carrier transit April 20 (5 sorties) → 24-sortie surge April 21 (highest non-exercise count since Justice Mission-2025) → 6-sortie pullback April 22 → 15-sortie anniversary spike April 23. Taiwan's armed forces deployed combat air patrols, naval ships, and coastal missile systems in response. With 21 days remaining before the Trump-Xi summit in Beijing (May 14-15), the PLA anniversary spike signals Beijing will maintain military pressure throughout the pre-summit diplomatic period rather than showing restraint to ease negotiations. Analysts note that the concentrated southwestern ADIZ focus (14 of 15 sorties) differs from the multi-sector pattern of the April 21 surge and more closely resembles baseline elevated-pressure operations rather than exercise rehearsal geometry.
