NL WARSHIP F831 — Military Ops · IMO 4601034

NL WARSHIP F831 has not broadcast an AIS position for 22 days. The most recent broadcast placed it in the North Sea, on 15 Oct 2026, 08:36 UTC. It was sailing from DEN HELDER to DEN HELDER. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

NL WARSHIP F831 broadcasts MMSI 245965000 and is registered as IMO 4601034, with call sign PAME. 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.

NL WARSHIP F831 is classified as a military ops vessel registered under the NL 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 NL flag list at /flag/nl.
