TLP 540 — Military Ops · IMO 4560876

TLP 540 has not broadcast an AIS position for 4 days. The most recent broadcast placed it in the Java Sea, on 2 Nov 2026, 08:18 UTC. It was sailing from SURABAYA to SURABAYA. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

TLP 540 broadcasts MMSI 525114078 and is registered as IMO 4560876, with call sign PLIS . 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.

TLP 540 is classified as a military ops vessel registered under the ID flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full military ops fleet at /vessel-type/military-special and full ID flag list at /flag/id.
