Ok, now if you read these articles, you will view the first ever posted top speed of a seawolf sub by the us military. Since the sub crash last week in the Indian Ocean and the death of a sailor, information has been slow to come out of the pentagon. I don't know if this was an error on information released in the rush to release news on the sub crash and death, but its on the web now, so I thought I would pass it on to you all at ATS.

65mph in a sub!

January 14, 2005: The USS Jimmy Carter (SSN 23), a modified Seawolf-class submarine, is used for missions the navy does not like to talk about. The Carter displaces 12,151 tons submerged, is 100 feet longer than a baseline Seawolf (453 feet compared to 353 feet).

SSN-23 and the Multi-mission Project
The new missions and design concepts outlined by the DSB and NDIA reconfirmed the soundness of the Navy's plan to provide one of the three Seawolf (SSN-21)-class submarines with advanced, versatile multi-mission functionality. The third of the class, USS Jimmy Carter (SSN-23) was chosen to serve as a test bed for studying the evolution of submarine missions in the 21st century. It will support classified research, development, test, and evaluation (RDT&E) efforts for notional naval special warfare (NSW) missions, tactical undersea surveillance, and undersea warfare concepts. The Navy, with funding approved by Congress to complete the Multi-Mission Project, has tasked General Dynamics Electric Boat Division (EB) to provide Jimmy Carter with additional volume and functionality to support new multi-mission opportunities. These changes will have no direct impact on the ship's organic warfighting capability but will give the submarine an enhanced payload capability with a more modular architecture. The required modifications will delay her scheduled delivery by approximately 27 months, until mid-2004, but the ship will be fully operational within a year after delivery.

Wow 65 mph!
Jeez, difficult to drive a boat underwater with no windows on it!

Teach the US navy to stay under the speed limit!

Guinness World Records,

Fastest Submarine:
"The Russian Alpha class nuclear-powered submarines had a reported maximum speed of over 74 km/h (40 knots)"



globalsecurity.org:
Alpha class subs - 83.34 km/h max
SSN-23 Jimmy Carter - 65 km/h max




???????

im a bit confused

If this is tru you are looking at 55 knots. i wonder how quiet it is at that speed?

Usually the faster submarines move, the more noise they produce and therefore will make sonars and weapons lock onto them more easily. The more noise the submarine makes it self will also degrade the accuracy of their own on board sonar because there are just too much noise to accurately detect other subs.

That is dependant on thier shape. From my understanding a huge amount of the noise comes from the pumps for the reactors and the like.

Also anechoic tiles can reduce the sound emitted out side the sub from the machinery that makes the ship move. Also dosen't the Sea Wolf use a pumpjet propulsor? Which is much quieter than conventional propulsion systems.

I'm confused; does this U.S. submarine go 65 MILES per hour or 65 KILOMETERS per hour??

according to 'official' SSN-23 specification - Kilometers Per Hour.

But the big differnece between the Alfa and the Seawolf:

Safety, the CCCP was pretty indifferent about the safety of its systems.
Noise, the ALfa could be heard from almost an ocean away as it was soooo noisy at full power.

man the Alpha Class has gotta be among the best looking subs out there IMO

Forget how much noise it makes just traveling at 65mph....How much noise did it make coming in contact with an underwater mountain at 65mph?

That's kilometers per hour vs. miles per hour. The US sub would smoke the Alpha IMHO.

Acording to globalsecurity.org and janes fighting ships it only goes about 40 MPH....what they do like stick NOS in it?
And the russian alpha is only
40MPH as well...

If you read the articles you will realize that the original poster misquoted the speed. The sub only travels at 65Km/h, which is still incredibly fast when you're underwater.. The Russian sub travelling at 40mph is approximately the same as 65km/h that the US sub travels at.

We must challenge the Russians to a "SUBMARINE DRAG RACE". That will settle this once and for all.

no way can a sub do 65 mph!!!! It just doesnt have the power. The resistance of a sub in deep water is proportional to the speed cubed. The re is a reason ships and subs havent got massively fast over the last 40 years!

Firs the Russians will have to scrap up enough money to actually put one of their subs out to sea fully operational. The best sub in the world is useless if you can't afford to get it out of the docks.

But a "normal" ships don't have nuclear propulsion with more than 30MW output!

Why not? They have already SUCCESSFULLY fired torpedos under water mach 1, why cant a sub go 65mph? Ill need to pull the article, but it was a Pupular Science issue this past year. I read someplace the Russians are chasing it too. Only huccup so far is they cant steer it yet.
