In depth: Astute

The nuclear submarine that can remain underwater for 25 years.

In a Barrow-in-Furness shipyard last October, Stuart Godden, the director of engineering for BAE Systems' submarines division in Cumbria, is narrating a slide show and comparing the UK's latest submarines programme -- the Astute class -- to Nasa's Space Shuttle programme.

"They've got a crew of five to seven, we've got 97 or so," he says. "They go out for a couple of weeks, we go out for 90 days. They typically went on 100 missions, we've got 25 years to operate. In terms of environment, they're 200 miles up, we're hundreds of metres beneath the sea. It's very benign up there, because there's no pressure or corrosion, whereas it's very high pressure and very corrosive under the sea."
