CSB 4036 — Wing In Grnd · MMSI 574004036

CSB 4036 has not broadcast an AIS position for 106 days. The most recent broadcast placed it in the South China Sea, on 24 Jul 2026, 02:48 UTC. It was sailing from HAI PHONG to HAI PHONG. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

CSB 4036 broadcasts MMSI 574004036. 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.

CSB 4036 is classified as a wing in grnd vessel registered under the VN flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full wing in grnd fleet at /vessel-type/high-speed-craft and full VN flag list at /flag/vn.

MarineRadar shows the latest AIS broadcast from CSB 4036 above, with current position, course, speed, and navigation status.

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 wing in grnd, CSB 4036 sits in the same design class as the other wing in grnds listed in the Similar Vessels section of the vessel page, or in the full wing in grnd directory at /vessel-type/high-speed-craft.
