DEFENDER — Local Vessel · MMSI 368219290

DEFENDER has not broadcast an AIS position for 4 days. The most recent broadcast placed it in the Gulf of Mexico, on 2 Nov 2026, 17:17 UTC. It was sailing from PORT ARTHUR to PORT NECHES. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

DEFENDER broadcasts MMSI 368219290, with call sign WDM5794. 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.

DEFENDER is classified as a local vessel vessel registered under the US flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full local vessel fleet at /vessel-type/cargo and full US flag list at /flag/us.

MarineRadar shows the latest AIS broadcast from DEFENDER 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 local vessel, DEFENDER sits in the same design class as the other local vessels listed in the Similar Vessels section of the vessel page, or in the full local vessel directory at /vessel-type/cargo.
