   September20 notices schedule New Taima and Taima Star evening sailings, following yesterday’s provisional outlook. A separate notice schedules Nangan–Dongyin service on September21–22. September21 evening service remains subject to weather and the following morning’s decision. These notices establish scheduled availability, not completed voyages; no military closure is stated.

   Aircraft sorties fall again; naval count steady for a second day
   共機架次再降；共艦數連兩日持平

   MND reports 5 aircraft sorties, 11 naval vessels and 6 other official ships, with all 5 sorties in its median-line/ADIZ subset. Aircraft fell 28→20→5 over three reporting days; naval vessels stayed at 11 for two days and other official ships rose 3→6. These figures do not measure airlift, unique fleets or territorial-airspace violations. Direct MND TLS failure continues. Official mirrors confirm counts; the Air Force end date is misprinted as September18, while the main MND indexed original and September20 MNA item support the September19–20 window.

   The September 19 notice schedules New Taima service between Keelung, Nangan and Dongyin. September 20 evening service is provisionally expected, subject to the next morning’s announcement and changing sea conditions. A timetable is not confirmation the voyage operated. No military restriction is stated in this notice.

   共機架次回落；共艦單日增加

   MND reports 20 aircraft sorties, 11 naval ships and 3 other official ships; 13 sorties in the median-line/ADIZ subset. Aircraft fell from 28; naval ships rose from 7. This follows the September 18 alert, with no new sustained naval increase established. Direct MND collection failed TLS. Official Air Force and MNA fallback pages confirm counts; MND indexed original resolves the Air Force mirror’s duplicated September 18 end date. These are the same official claim, not independent detections or territorial-airspace violations.

   The operator notice carried by Matsu Daily confirms a scheduled New Taima departure from Keelung at 22:30 on September 18, resolving yesterday’s provisional decision. Nanbei Star 2 is scheduled for Nangan–Dongyin on September 19 and the return on September 20. September 19 evening long-route service remains provisional until that morning’s announcement.

   CGA reports the premier’s September 18 Matsu visit to review a proposed NT$735 million coast-patrol/Fuao inspection facility. Approval is expected in 2026, construction in 2028 and completion in 2032, with space for about 190 personnel. These are planned dates and capacity, not a current deployment increase. General references to Chinese Coast Guard pressure do not describe a new dated incursion.

   CNA, citing a Presidential Office release, reports that President Lai inspected Taiwan’s three-day joint precision-missile exercise in Pingtung on September 18 and described the first integration of multiple attack-drone types. Record this as Taiwan training and attributed capability development. Its coincidence with rising PLA sorties does not establish causation or prove PRC mobilization; CNA and official material quoted within it are not independent corroboration.

   MND reports a separate September 17 joint patrol after the daily cutoff
   國防部另通報九月十七日每日統計截止後的聯合警巡

   MND, through its Military News Agency, reports 19 aircraft sorties from 08:45 Taiwan time, including 15 crossing the median line into southwestern and central airspace in coordination with naval vessels. The mix includes combat, support and unmanned aircraft; Y-8 electronic-warfare aircraft are not an airlift count. This partial-day event follows the separate 24-hour report ending at 06:00 (19 sorties, 17 median-line/ADIZ subset). Keep the windows separate; do not add this event to the daily series or a later daily total. No territorial-airspace violation or mainland buildup is established.

   Matsu Daily carries New Taima sailing notices for September 16 and 17 after earlier weather and maintenance disruption, plus Nanbei Star 2 service on September 17–18. These are schedules, not proof of completed voyages. The September 18 evening long route remains provisional pending that morning’s decision. Separate operator notices adjust Fuao–Langqi departures during September 16–30 and October 2–9 because low tidal water levels affect Langqi port; no military cause is stated. Exact revised times are in notice images and were not transcribed.

    馬祖：臺馬之星公告開航，保養與海象分列

    The September 15 notice schedules Taima Star’s evening departure from Keelung via Nangan and Dongyin back to Nangan, without a return to Keelung. This resolves the prior provisional sailing announcement, but does not verify a completed voyage. New Taima’s September 15 trip is suspended for maintenance; September 16 evening service is still provisional. Nangan–Daqiu’s September 16 service is cancelled for sea conditions. No military cause is stated.

    H I Sutton reports reviewing satellite images and interprets a ship under construction as a possible submarine-drone mothership. Its proposed role and capacity remain analyst assessments. Construction evidence does not establish operational readiness, deployment toward Taiwan or amphibious troop transport. ISW’s September 18 update repeats this assessment; this monitor has not independently analyzed the imagery.

    Aircraft activity continues rising; maritime counts do not show the same increase
    共機活動持續增加；船艦數量未呈現同幅上升

    MND reports 28 aircraft sorties, 7 naval ships and 2 other official ships for the window ending September 18 at 06:00, including a 24-sortie median-line/ADIZ subset. Daily sorties rose 4→8→15→19→28 across five reporting dates. The seven-day mean is 12.29 against 4.68 in the preceding 28 days (2.63×); naval means are 6.71 versus 7.43. This warrants a notice of sustained short-term air activity, not an invasion forecast. Yesterday’s 19-sortie partial patrol falls inside this full-day window and is not added again. These are official detections, not unique aircraft, airlift totals or territorial-airspace violation counts.

    Operator notices confirm New Taima’s September 14 outbound and September 15 return are cancelled for sea conditions, resolving yesterday’s uncertainty. Nanbei Star 2’s September 15–16 trip is also cancelled. Donghai Mingzhu announces an added Nangan–Dongyin trip for September 14–15. September 15 New Taima maintenance is a separate cause; a possible Taima Star evening sailing remains provisional. Announcements do not prove completed voyages. No military cause is stated.

    Matsu Daily carries notices for September 13 evening New Taima and Taima Star sailings, plus September 13–14 Nangan–Dongyin service. These are schedules, not confirmation of completed voyages. The September 14 evening long-distance service may be cancelled, pending that morning’s decision because of forecast sea conditions. Nangan–Daqiu is cancelled September 14 because tides hinder docking. No military cause is stated.

    海巡再通報金門事件，延續先前關注的模式

    Taiwan’s Coast Guard says the same four Chinese coast guard ships entered Kinmen restricted waters on September 11 and all subsequently left. It calls this the fourth episode of the week and the second consecutive day. Together with September 8 and 10, the reviewed accounts cover four episodes on three dates, not four incident days or sixteen distinct ships. This continues the pressure flagged on September 10; CGA’s interpretation of planned harassment remains an attributed claim without independent corroboration.

    The operator confirms that the September 11 outbound and September 12 return New Taima voyage is cancelled because of rough seas, resolving yesterday’s provisional notice. A September 12 evening sailing is expected but remains subject to the September 12 announcement. Separately, the Fuao–Langqi operator announces resumption from September 12 after assessing sea conditions as safe. These are route-specific operator plans, not independently verified completed sailings or evidence of military restrictions.

    海巡署通報本週第三次金門限制水域事件

    Taiwan’s Coast Guard says four Chinese coast guard ships entered Kinmen restricted waters on September 10 and all left after its response. It describes this as the week’s third episode and says the frequency has increased. Together with its two September 8 accounts, the reviewed evidence covers three episodes on two dates, not three incident days or twelve distinct vessels. The repetition warrants closer attention, but the frequency assessment remains attributed to CGA and lacks independent corroboration; no mainland buildup is established.

    The Maritime and Port Bureau’s September 11 notice cites an August 10 Taiwan Navy Headquarters letter and prohibits vessels from entering designated exercise waters on September 9–10,15–18 and21–24. This is a Taiwan-issued planned exercise notice, not a newly announced PRC closure. The English heading says southwestern waters while the attachment label refers to southeastern areas; exact boundaries and hours were not extracted, so use the original notice and attachments for navigation.

    Operator notices confirm cancellation of the September 9–10 and 10–11 New Taima round trips. They also announce September 11 cancellation of the Fuao–Langqi service and September 11–12 Nanbei Star 2 sailings; Taima Star cannot provide the advertised short-route support. All cite sea conditions. The September 11 evening New Taima departure is only provisionally doubtful, pending a September 11 announcement. These are route-specific announced weather disruptions, not evidence of military closure or complete isolation of Matsu.

    ISW interprets PLA discussions of civilian resources as future wartime requirements. Its linked September 13 PLA Daily original discusses replacing damaged military functions with civilian resources; this is doctrine, not a mobilization order. The linked CCTV amphibious-training page is dated September 8, although ISW describes a September 13 video. The text reports amphibious live-fire assessment but does not give a dated coastal concentration, force total or validated airlift increase. Video-specific drone claims were not independently verified. Keep publication dates distinct from unknown exercise dates.

    Taiwan’s Coast Guard reports morning and afternoon entries into Kinmen restricted waters by the same four Chinese coast guard ships on September 8, with all leaving after its response. The afternoon notice updates the morning report: this is one daily record covering two reported episodes, not eight distinct vessels or four incidents from mirrored pages. These are attributed official claims without independent corroboration. The record does not by itself establish a sustained increase or mainland force concentration.

    September 8 transport notices revise September 9–10 Nangan–Dongyin service: the original ferry is scheduled to resume September 9 as seas ease, with a substitute planned September 10 because of poor sea conditions. A separate notice identifies September 8 maintenance and says a possible September 9 evening cancellation remains subject to confirmation. These are published plans, not verified completed sailings or blanket island isolation. The stated causes are sea conditions and maintenance, not military restrictions.

    Taiwan’s Coast Guard says a China Coast Guard ship entered Dongsha’s restricted waters on September 7. Its notice described a confrontation at publication; a later outcome has not been verified. The agency also reported 12 expulsions of Chinese coast guard vessels from Dongsha waters during 2026 to date. That is its cumulative figure, not this database’s independent incident count. This is an attributed official report, not independently corroborated evidence of mainland force massing.

    A September 6 CNR Military report says a 71st Group Army brigade conducted live-fire assessment with newly received 155mm self-propelled artillery at a training ground in eastern Anhui. The exercise date and equipment count are not stated. A September 9 SCMP article frames the upgrade as Taiwan-facing firepower, citing state media. The primary written account supports an equipment-and-training report in Anhui; it does not establish a current concentration on the Fujian coast, new amphibious deployment, or military-airlift increase. Independent corroboration is absent.

    A Taiwan Coast Guard clarification describes two Chinese coast guard ships east of Green Island on September 3 and disputes China’s description of an enforcement patrol. The body dates the activity to September 3; the retrieved page shows a September 8 update while RSS carries September 3, so the original publication date remains unverified. This is a historical official account added today, not a new September 8 event or evidence of a territorial-water entry. The underlying PRC statement has not been independently reviewed.

He highlights helicopter transport, amphibious vessels and logistics development. The article also says landing capabilities remain inadequate at this stage.

    ISW reports an August 28 revision to China’s National Defense Mobilization Law, effective October 1, and assesses possible implications for civilian sealift, drones and other technology. An official promulgation notice retrieved through search supports the adoption and effective dates; the linked NPC full text was unavailable for direct review. The broader legal interpretation remains attributed to ISW. This is a change in a legal framework, not evidence that requisition, mobilization, a transport surge or force concentration is occurring.

    ISW reports roughly monthly two-ship coast guard rotations east of Taiwan, most recently September 4, using Starboard data. It interprets the pattern as normalization of a persistent presence. Xinhua separately attributes an August 10–31 seabed survey to the natural-resources ministry. ISW could not independently verify the reported militia escort.

    August snapshot provides retrospective context, with unresolved count differences
    八月海峽快照提供回顧脈絡，數值差異尚待釐清

    TSM describes lower August air activity alongside continuing maritime pressure, citing MND and CGA. It reports 171 sorties and 7.7 daily naval detections; this monitor retains 176 sorties and 7.81 for reporting windows ending August 1–31. Shifting those windows one day gives 173 and 7.65, so date alignment alone does not fully resolve the difference. TSM also inconsistently describes 171 as tied with March while giving March as 173, and calls the 11-sortie patrol one of the two largest days despite listing a 20-sortie day. Preserve both accounts; do not overwrite primary daily records. This is August context, not independent confirmation of a September buildup.
