RMN 331 — Military Ops · MMSI 533300001

RMN 331 has not broadcast an AIS position for 20 days. The most recent broadcast placed it in the South China Sea, on 17 Oct 2026, 08:49 UTC. It was sailing from KOTA KINABALU to SANDAKAN. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

RMN 331 broadcasts MMSI 533300001, with call sign 9MJP . 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.

RMN 331 is classified as a military ops vessel registered under the MY 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 MY flag list at /flag/my.
