The first of the UK's new generation of nuclear-powered attack submarines has been unveiled in Cumbria by the Duchess of Cornwall.
Due to enter service in 2009, BAE Systems' Astute is the most advanced submarine of its kind and comes bristling with the very latest in military technology.
BAE said: "With a radar signature equivalent to a dolphin, it can remain undetected thousands of miles from home and hundreds of metres underwater.
"In the right conditions it can detect the QE2 leaving New York harbour from the English Channel."
As some of you know, I spent some time in the US Submarine service. I enjoyed my time there, but we never had anything like this. Pretty damn cool.
