Britain launches nuclear sub that can hear a ship from across the Atlantic
this is london ^ | 08.06.07

Posted on 06/08/2007 10:40:35 AM PDT by george76

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."

its key asset is its stealth. Even with a nuclear reactor and four powerful turbines propelling it through the water, less than one watt of power is radiated, making it incredibly quiet.

Its nuclear reactor means that it will never need to be refuelled in its 25-year lifetime.

The submarine - almost half as big again as the Royal Navy's current fleet of attack boats - is one of three under construction at the BAE Systems shipyard in Barrow-in-Furness.

I wonder what the real numbers are...

“It will be able to remain hundreds of metres under water for up to 90 days at a time while keeping its 98-strong crew safe as they sleep, eat and breath within metres of a nuclear power plant. “

It's pretty impressive. As to how it compares it's probably on par with the latest U.S. boats. Let's just say I'm glad she's on our side.

"With a radar signature equivalent to a dolphin"

Could it be that they mean "sonar" signature?

We had some of those at Prudhoe Bay to drag around the housing modules that were brought up prefab on the barges. Those modules were the size of that submarine part. They also used the crawlers at Canaveral to move the Saturn moon rockets. We used to joke that if somebody hikacked one of the crawlers and drove it south we could still see him going down the road 24 hours later.

My understanding is that the Astute is as quiet as the previous stealth ace, the quietest German HK diesel (the Dolphin class). However it's a nuclear sub.

The Astute's power pack has (apparently) the same acoustic signature as an electric battery.

Yes. Sit in one of them when you can. It’s like inside the cockpit of a Formula I racer. Not so fast but about as low, and that baby will haul!

We’ve had all the sea lanes bugged with Texas Instrument listening devices for decades that can tell by a ships resonant frequency withing a few feet where every ship in the world is.

Thanks for the reality check, agere. There is a strong perception on these boards that the UK's Islamification is far worse that America's. I hope that Britons are waking up with regard to militant Islam as most are here in the states.

4 turbines?

Maybe 2 for propulsion, two for turbine generators? That’s a fairly standard layout.

4 for TG’s, plus a electric prop? That would be quieter, but a little bit heavier. We didn’t have that setup while Rickover was controlling ER’s.

On the down side, if threatened by twelve Iranians in a rubber boat, “Astute” will surrender...

I think it is similar to the “crawler” that moves out shpace shuttles to and from the launching pads.

The best picture I have seen of a real OTH truck/trailer is a photo of a piece of mining equipment moved from Salt Lake City to Golconda, Nevada to a gold mine. It took something like 32 days for the trip and moved at about 2 miles an hour. It was articulated to make “turns and go up and down hills.

Actually, they did try an electric propulsion boat, but they only made one, as it didn’t work so well. I don’t remember which boat (I believe it was a 637).

Something like fifty wheels under it. The ones we had used tracks, but we had gravel roads to start with or they would have been gravel roads afterwards anyway.

“With a radar signature equivalent to a dolphin...”

I’m a little confused by this statement. What relevance is a radar signature when a submarine remains underwater?

I'm pretty sure 90 days is the limit due to food.

And maybe TP.

Unless, of course, they are ordered to listen to Sheryl Crowe.

I remember reading one article about the then-new LA class boats. They would leave port with food packages stacked all over the place.

The writer is goofed up - Sonar is underwater measure of stealth.

(Though radio masts and periscopes that are above water are treated with RAM coatings to reduce radar reflections.)
