Taiwan’s Ministry of National Defense has published a daily count of detected PLA aircraft, naval vessels and government ships every morning since 2020. It is the most consistently maintained open-source series in the Indo-Pacific, and for four years it moved in one direction. Summed across the first six months of 2026, the fighter component comes to 1,334 sorties — less than half the figure for the same period in 2025, and the lowest operational tempo since 2023.

The past 48 hours in the Taiwan Strait are best understood against two converging pressures: the ongoing Balikatan 2026 exercises reshaping the military geometry of the first island chain, and the approaching Trump-Xi summit that has introduced a layer of calculated restraint — and calculated anxiety — into Beijing’s Taiwan posture.

Balikatan and the PLA response. The combined Balikatan 2026 exercises, running April 20 through May 8, mark a structural inflection. Japan is participating for the first time in an active operational role, not merely as an observer. The exercise has prominently featured sea denial systems — the US Navy-Marine Corps NMESIS and Japan’s Type 88 anti-ship missile — deployed to the Batanes Islands in the Luzon Strait. The positioning is deliberate: anti-ship systems in the Batanes directly contest the PLAN’s primary breakout route from the first island chain through the Luzon Strait. Beijing read it accordingly. The Southern Theater Command announced on April 24 that a surface task group led by a Type 055 guided missile destroyer, accompanied by a Type 052D destroyer, a Type 054A frigate, and a replenishment vessel, had conducted exercises east of Luzon. The STC conducted additional South China Sea exercises on April 28, citing Philippine provocations. Unverified satellite imagery circulated on PRC social media appeared to show the carrier Liaoning operating in the South China Sea with a three-destroyer, six-frigate escort group — Liaoning had transited the Taiwan Strait southbound on April 20. Separately, the PLAN’s new Type 076 landing helicopter dock departed Shanghai for sea trials in the South China Sea around April 22, possibly in conjunction with the response posture. The PLA also released footage of YJ-20 hypersonic anti-ship missile test launches, timed to coincide with the Balikatan peak, including previously unseen shots of the launch sequence beyond what was disclosed in December.

The Taiwan crisis is forecast as a future event. It is also a present event, conducted continuously across a spectrum of activity that does not produce headlines but does produce strategic effect. The grey zone war over Taiwan has been running for most of the last decade. Treating it as preliminary to the real war misses that the grey zone is the real war for now, and may remain so indefinitely.
