A large-scale search operation involving multiple agencies is currently underway off the coast of County Donegal, Republic of Ireland, following the disappearance of a UK navy crew member. The Irish Department of Transport (DfT) confirmed that the individual was last seen around 22:30 (local time) on Friday near Tory Island. The Irish Coast Guard received a distress call from a UK naval support vessel early Saturday morning, prompting the immediate launch of search and rescue efforts. The Royal Navy is actively participating in the operation, focusing on locating the missing crew member from the Royal Fleet Auxiliary. The search involves the Irish Coast Guard, the Irish Air Corps, the Royal National Lifeboat Institution (RNLI), and the UK naval vessel. The Malin Head Coast Guard is coordinating the operation, which spans the northwest coast between Tory Island and Eagle Island in County Mayo. Air support includes the Coast Guard’s fixed-wing plane Rescue 120F from Shannon Airport, the Coast Guard helicopter Rescue 118 from Sligo, and the Irish Air Corps plane CASA 284. Additionally, the UK Naval support vessel and three RNLI all-weather lifeboats from Ballyglass, Arranmore Island, and Lough Swilly are conducting sea searches. The operation highlights the collaborative efforts of Irish and UK authorities in responding to maritime emergencies.
