Astute Class SSN

[DanCanovas]

found a great site with good computer generated images and loads of info on the project. Check it out here http://navy-matters.beedall.com/astute.htm

Much to read. Nice find. Thanx! :)

Bad link could you repost?

[DanCanovas]

The two vessels outboard of the T45 are part of a disputed order to Brunei.

That super-structure looks like one of Death Star's Laser Towers.

[Linton]

A replica of the superstructure is on top of a hill in Pompey as part of the trials process.

[ABBAFAN]

ah the links work now nice pics of future RFAs there too!

Good find DanCanovas! The shipyard is a few miles down the coast from me.

I read that the Astute class can "detect QE2 leaving New York harbour from the English Channel". I find that hard to believe.

I've been lucky enough to go onboard HMS Vigilant, a Vanguard class sub. They used quite old technology because it was tested as reliable, this new sub must be something else!!!

I would be interested to know how the Astute compares to the equivalent US subs... anyone know?

:-?

Hopefully it's as lethal as it is ugly.

Have you read the sun article on it. So many errors as to be unbelievable.

Anyway I think the dolphin nose is probably more hydrodynamic

Bill & Drebbel posted some additional articles on the main Subsim page,

The Astute, the first attack submarine to be built in almost two decades, is the "most stealthy in the world" and will put the Navy at the "top of the premiership", commanders said.

It is also the first submarine not to have a conventional periscope. Instead a fibre optic tube - equipped with infra red and thermal imaging - pops above the surface for three seconds, does one rotation and then feeds an image in colour that can be studied at leisure.


Sheesh, I guess they assume the readers are adding the words Royal Navy in front of the word "submarine" :dead:

Excluding the pioneer submarines (Pre WWI), I do belive that this is incorrect. The Virginia Class uses the photonics mast, not a periscope.



...is the "most stealthy in the world" and will...

More than a Traffy or a Gotland? That's amazing.

Is it just me or does this look photoshoped?

Agreed.

Maybe it's should say that the QE2 can detect it in New York when the sub is in the English Channel?:rotfl:

Uh well, seeing how the sub is not launched or anything yet, you tell me if it's photoshopped or not :p

I can't see that that would be usefull info as the sound would surely take hours to reach the sub...that said I don't know the speed of sound in water and I'd be too lazy to calculate it anyway.

[horrgakx]

LOL! ;) You're absolutely right - that is an "artists impression" of how the sub WILL look when it is launched :) Though I think it looks like it is sitting too high in the water.

Not impossible. The old legends say that the Alfa, at high speed, can be tracked using a Bermuda SOSUS array when it is in the Barents. Under certain conditions, low frequency sound can travel intercontinental distances underwater.

"You want to know how noisy the Russian Foxtrots were?”
Take this rendition: SSN departs Norfolk, passes the curve, and submerges. Sonar does its first submerged sweep, reports 'Conn, Sonar, contact bearing 090 degrees, designate Sierra One, Russian Foxtrot Diesel Submarine, just exiting the Straights of Gibraltar.' "
-- Dave Goodson- COB SS(B) 39 Cobra, Pier 48, Seattle

:lol: :lol: :lol:

[Tchocky]

Kaz, that's an Alfa at high speed.....I'd say it's like a lawnmower inside your head :D
