On March 20, following operations involving the Boracay and the Grinch, the UK Navy deployed commandos aboard the Deyna, a 250-meter-long oil tanker flying the flag of Mozambique. The vessel, which departed from Murmansk, was navigating south of the Balearic Islands en route to Port Said, Egypt. This operation aimed to verify the presence of the Russian “ghost fleet” within UK territorial waters.
