US, Japan Rehearse Strikes to Counter PLA Control Near Taiwan

US and Japanese forces have rehearsed strike scenarios designed to challenge the People’s Liberation Army’s control of waters near Taiwan, according to a report from the South China Morning Post. The exercise is the latest in a string of allied drills near the island that Washington and Tokyo have cast as routine but that Beijing treats as a direct challenge to claims it asserts over the surrounding waters.

Specific units, platforms, and the precise locations rehearsed have not been detailed beyond the initial SCMP report. America Strikes will update this story if US Indo-Pacific Command, Japan’s Ministry of Defense, or China’s Ministry of National Defense issue their own statements.

A contest over who controls the water

The PLA has spent the past several years building a layered presence in the waters around Taiwan — coast guard patrols, naval task groups, and air defense identification zone incursions — that functions less as a conventional blockade than as a slow assertion of control short of open conflict. A US-Japan rehearsal aimed squarely at challenging that control marks a shift in emphasis from deterrence-by-presence toward deterrence-by-demonstrated-capability: showing Beijing, concretely, that allied forces have planned for scenarios in which they would need to contest PLA-controlled waters rather than simply sail through them.

That shift lands one day after China demonstrated its own rapid missile response capability during a separate round of US-Japan drills in the same waters, as America Strikes previously reported. Taken together, the two episodes describe a strait where neither side is waiting for the other to make the first move in a crisis — each is instead rehearsing, in public view, how it would respond if the other did.

Taiwan’s own buildup

Taiwan has not been a passive audience to this exchange. The island’s military has been accelerating development of autonomous drone swarms intended to blunt PLA coercion at a fraction of the cost of crewed patrol vessels or fighter sorties, a buildup America Strikes detailed in coverage of Taiwan’s drone program. A US-Japan rehearsal focused on contesting Chinese control of nearby waters complements that approach: Taipei’s drones are built for persistent, low-cost denial close to the island, while Washington and Tokyo are signaling they retain the heavier strike capability to back that denial up if a crisis escalated beyond what Taiwan’s own forces could handle alone.

Neither track has produced a direct incident. Both are designed, at least publicly, to operate as signaling rather than provocation — demonstrations meant to be observed and factored into the other side’s planning rather than acted upon in the moment.

Washington’s bandwidth problem

The timing raises a familiar question for US planners: how much capacity Washington has to manage simultaneous flashpoints. The Pentagon and State Department are already tracking a renewed risk of an Israeli-US strike on Iran, a Russia-Ukraine war where trilateral peace talks have just restarted after stalling for weeks, and now a Taiwan Strait rehearsal explicitly framed around contesting Chinese control. None of these theaters is isolated from the others. Every carrier strike group, submarine rotation, or munitions shipment allocated to the Indo-Pacific is one not immediately available to the Middle East or Eastern Europe, and vice versa — a constraint that shapes how aggressively Washington can posture in any single theater without drawing down its readiness in another.

What to watch

America Strikes is tracking whether China’s Ministry of National Defense responds publicly to the rehearsal, whether Japan’s government characterizes the exercise as routine or elevates its language given the recent pattern of tit-for-tat signaling, and whether Taiwan’s own military references the drills in its next public briefing. A single rehearsal does not change the balance of forces in the strait, but a pattern of them — paired with China’s own missile response demonstration and Taiwan’s drone buildup — points to a strait where every actor is now rehearsing for a crisis none of them has said they want.
