POLAR KING — Cargo · IMO 8711320

POLAR KING has not broadcast an AIS position for 13 days. The most recent broadcast placed it, on 25 Oct 2026, 15:17 UTC. It was sailing from ARKHANGELSK ANCH to PEVEK. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

POLAR KING broadcasts MMSI 273352370 and is registered as IMO 8711320, with call sign UBTI3. 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.

POLAR KING is classified as a cargo vessel registered under the RU flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full cargo fleet at /vessel-type/cargo 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.

As a cargo, POLAR KING sits in the same design class as the other cargos listed in the Similar Vessels section of the vessel page, or in the full cargo directory at /vessel-type/cargo.
