The ship loitered until 2 pm the next day, before the Royal Navy dispatched a Wildcat helicopter from Yeovilton naval air station in Somerset. The location of the vessel's overnight stop is particularly noteworthy because it's less than a mile from five undersea cables that connect Britain to Spain, Portugal, Canada, and the U.S. The report follows a revelation in September, which stated that a Russian "military spy ship" had been monitored surveilling and mapping undersea cables along Europe's Atlantic coastline. UK shadow security minister Alicia Kearns said of this week's incident: "The movements of this Russian ship are deeply suspicious. The UK Department for Transport said "a clear warning" was issued to Sinegorsk instructing it to leave UK waters "after it entered to undertake essential safety repairs."
