ARGO — Dive Vessel · IMO 8601903

ARGO has not broadcast an AIS position for 18 days. The most recent broadcast placed it in the South Pacific Ocean, on 19 Oct 2026, 21:45 UTC. It was sailing from APIA to MAJURO. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

ARGO broadcasts MMSI 312208000 and is registered as IMO 8601903, with call sign V3OW5. 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.

ARGO is classified as a dive vessel vessel registered under the BZ flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full dive vessel fleet at /vessel-type/military-special and full BZ flag list at /flag/bz.

MarineRadar shows the latest AIS broadcast from ARGO 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 dive vessel, ARGO sits in the same design class as the other dive vessels listed in the Similar Vessels section of the vessel page, or in the full dive vessel directory at /vessel-type/military-special. ARGO has a gross tonnage of 244 GT.
