A huge fire that ripped through a nuclear submarine factory damaging a £1.3billion vessel was caused by an exploding tool, it has been reported.
Highly-flammable rubber tiles on the hull of nuclear sub HMS Agincourt ignited after a sand-blaster blew up at the BAE Systems factory in Barrow, Cumbria just after midnight on Wednesday.
The tiles, which are designed to absorb enemy sonar, are made of a foam-like polymer with a source saying the fire ‘smelt like burning rubber but worse’.
The revelation debunks fears the blaze was caused by Russian sabotage, with sources saying it was merely an industrial accident.
Security services have been on high alert for Russian arson and sabotage attacks after mystery fires wrecked havoc across Germany, the Baltic and the UK.
The historic BAE Systems shipyard has built all but three of the UK’s fleet of nuclear submarines and has been producing vessels for more than 100 years. The latest, HMS Agincourt, is due for completion in 2026.

Two night shift workers and five BAE firefighters were hospitalised for smoke inhalation following the blaze.
Employees were also shut out of burnt-out sections of the the site that were deemed ‘unsafe’.
Locals said the fire appeared to be centred on the six-acre Devonshire Dock Hall, the main construction site, where the £1.3billion sub was being assembled.

Locals took to social media to tell of their concerns as the fire at the massive factory could be seen for miles around.
One man told the Daily Mirror he had heard a ‘big thump’ from the building earlier in the night.
Another resident asked: ‘Isn’t this really bad?’ A further local said: ‘It’s scary because the last thing you want is BAE of all places up in flames. But if it was a threat to life or the town they would have emergency-warned everyone.’
