RIO ARLANZA — Law Enforce · IMO 9871543

RIO ARLANZA has not broadcast an AIS position for 124 days. The most recent broadcast placed it in the Mediterranean Sea, on 8 Jul 2026, 13:00 UTC. It was sailing from CAGLIARI to CADIZ. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

RIO ARLANZA broadcasts MMSI 225991173 and is registered as IMO 9871543, with call sign EBSL. 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.

RIO ARLANZA is classified as a law enforce vessel registered under the ES flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full law enforce fleet at /vessel-type/military-special and full ES flag list at /flag/es.

MarineRadar shows the latest AIS broadcast from RIO ARLANZA 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 law enforce, RIO ARLANZA sits in the same design class as the other law enforces listed in the Similar Vessels section of the vessel page, or in the full law enforce directory at /vessel-type/military-special.
