Key Judgment

The three Taiwan MND releases establish that the ministry reported a fall and partial rebound in detected aircraft sorties across adjacent daily windows, while its reported PLAN ship count remained at six. They do not independently establish total PLA activity or explain the operational cause of the variation.Translation unavailable; showing original.

What Changed

Taiwan MND reported 10 aircraft sorties for the 24 September release, 2 for 25 September, and 5 for 26 September; reported PLAN ships remained at 6 in all three windows.Translation unavailable; showing original.

Evidence

The reported sequence supports a moderate-confidence bounded judgment about the ministry’s publications, not total PLA activity.Translation unavailable; showing original.
