PP 3570 — Law Enforce · MMSI 416143900

PP 3570 has not broadcast an AIS position for 207 days. The most recent broadcast placed it in the East China Sea, on 16 Apr 2026, 05:04 UTC. It was sailing from TAIPEI to TAIPEI. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

PP 3570 broadcasts MMSI 416143900, with call sign SSD. The MMSI is the radio identifier used by AIS; the IMO number stays with the ship for life and does not change with re-flagging or sale.

PP 3570 is classified as a law enforce vessel registered under the TW flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full law enforce fleet at /vessel-type/military-special and full TW flag list at /flag/tw.

MarineRadar shows the latest AIS broadcast from PP 3570 above, with current position, course, speed, and navigation status. Tap "View on map" to centre the live tracker on the vessel and watch its movement update in real time. The same data is available offline-friendly in the iOS and Android apps.

AIS transponders broadcast position every 2 seconds when underway at high speed and up to every 3 minutes at anchor. The position you see refreshes whenever the ship is in range of a coastal AIS receiver or a satellite pass — typically seconds in coastal waters and minutes offshore.

As a law enforce, PP 3570 sits in the same design class as the other law enforces listed in the Similar Vessels section of the vessel page, or in the full law enforce directory at /vessel-type/military-special.
