Britain launches massive sub that can hear a ship from across the Atlantic | News | This is London: "She is four years late and a massive £900million over-budget.

But when the Royal Navy's super-sub HMS Astute finally arrived, she made for an awesome sight.

More complex than the space shuttle, and able to circumnavigate the globe without surfacing, the 7,400-ton monster is the largest and deadliest hunter-killer submarine ever built."
