Question 1

Where is ROK right now?

Accepted Answer

ROK has not broadcast an AIS position for 5 days. The most recent broadcast placed it in the Sea of Japan, on 4 Sep 2026, 00:24 UTC. It was sailing from BUSAN to BUSAN. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

Question 2

What are the identifiers for ROK?

Accepted Answer

ROK broadcasts MMSI 440800053. 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.

Question 3

What type of ship is ROK?

Accepted Answer

ROK is a maritime vessel registered under the KR flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder and full KR flag list at /flag/kr.

Question 4

How can I see the live position of ROK?

Accepted Answer

MarineRadar shows the latest AIS broadcast from ROK 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.

Question 5

How often is ROK's position updated?

Accepted Answer

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.

Question 6

What class is ROK?

Accepted Answer

The vessel's design class is inferred from its dimensions, gross tonnage and dead weight, all of which are listed in the Identity and Specifications panels on the vessel page.
