UK submarine put ferry passengers in danger of collision, report finds

Inquiry says possible collision averted in Irish Sea in 2018 after ferry altered course

Ferry passengers were in immediate danger when a nuclear-powered submarine almost collided with a ship that sailed out of Belfast harbour, an accident investigation report has found.

An inquiry by the Marine Accident Investigation Branch concluded that the Royal Navy submarine and Stena Superfast VII ferry came within 50-100m of each other in the North Channel in November 2018, after the submarine underestimated the ferry's speed. It was the third near-miss between navy submarines and a surface vessel in four years.
