Former and other names

Names attested for this ship other than its current name.

Name	Evidence	Date	Source
BRITISH WARSHIP	Former name, change seen on AIS	Oct 6, 2026	AIS (vessel's own broadcast)

A sanctions list's date is the earliest date the list shows the name, not when the ship took it. A name on a list is shown as a former name only where AIS shows the ship using another name after that date; otherwise it is listed as a name the list uses. AIS name changes are dated when Voydar saw them.

Port calls

Two kinds of evidence, kept apart: calls Voydar detected from the ship's AIS positions, and arrivals and departures published by port authorities and customs records.
