Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

OTB 2 broadcasts MMSI 232027844, with call sign MHJY9. 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.

OTB 2 is classified as a military ops vessel registered under the GB 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 GB flag list at /flag/gb.
