Russian attack submarines have conducted missions around the Irish Sea twice since the 2022 invasion of Ukraine, three people familiar with the matter said, an unprecedented move by the Kremlin that forced the UK military to take steps to protect British and Irish waters.

The first deployment of a Russian Kilo-class submarine close to the Irish Sea, which separates the island of Ireland from Great Britain, happened around 18 months ago, said the people, who asked not to be identified discussing private assessments. The second occurrence took place more recently. The extent of the submarine movements went beyond what UK officials had previously seen, they said.
