FORTRESS — Cargo · IMO 9126455

FORTRESS has not broadcast an AIS position for 156 days. The most recent broadcast placed it in the South China Sea, on 4 Jun 2026, 14:28 UTC. It was sailing from SINGAPORE to SINGAPORE ANCH. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

FORTRESS broadcasts MMSI 257507000 and is registered as IMO 9126455, with call sign LAJD8. 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.

FORTRESS is classified as a cargo vessel registered under the NO 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 NO flag list at /flag/no.

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.

FORTRESS is classed by DET NORSKE VERITAS, the classification society responsible for inspecting the vessel against safety, structural and operational rules. As a cargo, FORTRESS 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.
