CALLISTO — Tanker · IMO 9040077

CALLISTO has not broadcast an AIS position for 8 days. The most recent broadcast placed it in the North Pacific Ocean, on 1 Nov 2026, 11:50 UTC. It was sailing from VLADIVOSTOK to VLADIVOSTOK. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

CALLISTO broadcasts MMSI 273215290 and is registered as IMO 9040077, with call sign UBBV8. 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.

CALLISTO is classified as a tanker vessel registered under the RU flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full tanker fleet at /vessel-type/tanker and full RU flag list at /flag/ru.

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.

CALLISTO is classed by GERMANISCHER LLOYD, the classification society responsible for inspecting the vessel against safety, structural and operational rules. As a tanker, CALLISTO sits in the same design class as the other tankers listed in the Similar Vessels section of the vessel page, or in the full tanker directory at /vessel-type/tanker.
