Skip to comments.Britain launches nuclear sub that can hear a ship from across the Atlantic

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.

What say our naval FReepers about this boat? How does it compare to American subs?
Why is the Duchess of Cornhole unveiling anything?.........
I think it’s time the US Navy Atlantic Fleet start feeding the sailors lots of beans...
Be thankful it's only a sub she's unveiling.
The truck is higher tech than the Deathstar it is carrying.
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.
Can you hear me now?
I’m sure the subs will serve Allah well.
That truck looks like fun to drive.
But can this sub stop an Iranian navy canoe from seizing British sailors?
Don't want any more hostages y'know....
Yeah, but would they be able to hear THIS in the Atlantic?
One Ping Only!
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.
Thanks for the ping—nice boat!
Britain. 3% Muslim.
America: 3% Muslim.
You are welcome.
I downsized the picture for folks on dail up.
Hmmm.....our boats could do this in the 60s. :-)
Do the crawlers for the saturn rockets go one mile in three hours ?
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.
Don’t make me watch that... again.
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.
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...
The truck is higher tech than the Deathstar it is carrying.””
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.
(wry smile) There is a strong perception on FR that the UK is like the last reel of “Dawn of the Dead”, with Zombies feasting upon our scooped-out brains :0)
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?
Britain. 3% Muslim.
America: 3% Muslim.
We are free citizens and we have guns.
They are subjects and are unarmed (except for criminals and muslims)
Cool. Almost reminded me of an Akula though at first glance.
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.
So if it floats it weighs less than a duck?
Heh. The Duchess of Cornwall at the submarine races.
I guess I should have added “click at your risk...”
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.)
