A fire broke out overnight at BAE Systems’ nuclear submarine shipyard in Barrow-in-Furness, England, sending two people to the hospital due to smoke exposure. The main assembly area was evacuated, and authorities confirmed there was no nuclear risk involved. Local fire services advised residents to keep windows closed as crews worked for hours to extinguish the flames. An investigation is underway, though the cause remains unknown. The facility is currently constructing four Dreadnought-class submarines for the Royal Navy, set to replace the Vanguard fleet in the coming years.
