NRP ZARCO — Military Ops · MMSI 263143000

NRP ZARCO has not broadcast an AIS position for 144 days. The most recent broadcast placed it in the North Atlantic Ocean, on 16 Jun 2026, 15:43 UTC. It was sailing from SETUBAL to COVA DA PIEDADE. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

NRP ZARCO broadcasts MMSI 263143000, with call sign CTEH . 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.

NRP ZARCO is classified as a military ops vessel registered under the PT flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full military ops fleet at /vessel-type/military-special and full PT flag list at /flag/pt.

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.
