JO HAM 1 has not broadcast an AIS position for 17 days. The most recent broadcast placed it, on 20 Oct 2026, 11:49 UTC. It was sailing from ONNE to ONNE. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

JO HAM 1 broadcasts MMSI 657215673 and is registered as IMO 9801641. 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.

JO HAM 1 is classified as a military ops vessel registered under the NG 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 NG flag list at /flag/ng.
