Boracay, a Benin-flagged tanker, had just changed its name from Pushpa. Under that name, it was monitored sailing west around Denmark last week, and was cited by naval experts as one of a handful of Russia-linked vessels that may have been involved in the drone incidents.
Copenhagen airport was closed for four hours in the evening of 22 September and Aalborg airport two days later, after drones were sighted in Danish airspace. None, however, were shot down and while Denmark has pointed the finger at Russia its investigators have not been able to say who is responsible.
One line of inquiry is that the drones almost certainly larger delta or fixed-wing craft were launched from a ship or ships near Denmark, giving the countrys military little time to respond. Though the drones identity is not known definitively, such drones can be launched from a catapult that could easily be carried on a large ship.
Investigations by Danish media have also identified two other commercial vessels, the Astrol-1 and the Oslo Carrier-3, as sailing in the region at the time, and a Russian warship, the Aleksandr Shabalin, which was filmed by a Danish tabloid from a helicopter south of Langeland, at the very west of the Baltic.
