Found this article on the net, translated it, and here it is:
"The British nuclear sunmarine Tireless has collided with an unknown object at the North Pole, and the sub has now returned home to the Faslane base at Clyde in Scotland. There's no damage to the reactor on board. Experts believe that it has hit an iceberg, but the British Defence has no comments on the issue, according to The Times. Tireless had a serious problem back in 2000, where the reactor was close to a thermal meltdown. It's not the first time that UK sub's has difficulties finding their way under water, and avoid collisions. Last November, the
sub Trafalgar ran aground, and the damage runs at $8.000.000. British Defence: "These things happen, they are being investigated as they happen."
The sub, build in 1985, is equiped with state of the art systems that should be able to find everything in the water, enemy sub's......and icebergs."
That's two acidents this yr, let's hope it stops here.
