PLA 32 Sorties June 4 — NEW All-Time Non-Exercise Record; 25 of 32 Cross Median Line into ALL FOUR ADIZ Sectors; 10 PLAN Vessels + 5 Ships; Tiananmen 37th Anniversary

Taiwan's Ministry of National Defense detected 32 PLA aircraft sorties in the 24-hour window ending at 06:00 local time (UTC+8) on June 4, 2026 — a NEW all-time non-exercise record, surpassing the previous record of 29 sorties set on May 2, 2026. Twenty-five of 32 sorties (78%) crossed the Taiwan Strait median line, entering all four ADIZ sectors simultaneously: northern, central, southwestern, and eastern. Ten PLAN vessels and 5 official ships operated around Taiwan — highest ship count since May 22's 10-vessel post-summit high. The four-sector simultaneous penetration geometry (N+C+SW+E) matches the blockade-rehearsal pattern seen in major prior surges (May 20: 24 sorties, May 7: 22 sorties, May 2: 29 sorties record). June 4 marks the 37th anniversary of the 1989 Tiananmen Square crackdown — Taiwan President Lai Ching-te called on China to 'face up to the June 4 incident, acknowledge the truth, and open the door to reconciliation and dialogue.' Taiwan held a candlelight vigil in Taipei (~500 attendees, themed 'Memory Beyond Borders, Resistance Without Boundaries'). The PLA surge came immediately after Computex 2026 (June 2-5) and the day after Secretary Rubio's Senate testimony reasserting US arms sales independence from Beijing. June 3's 18-sortie surge was followed by this record June 4 surge — two consecutive escalatory days (18→32). The prior three non-exercise records: May 2 (29 sorties), Apr 26 (28 sorties), Apr 21 (24 sorties). Extended sequence: ...→7→18→32. ROC Armed Forces deployed CAP aircraft, naval vessels, and coastal missile systems in response.
