It is in Submarine warfare that China truly lags behind. The USN's lead on this regard is enourmous. The 093 subs are the quitest SSN sub in the PLAN arsenal, but the USN has proven capability to detect and track the world's quitest SSN boats. China needs to invest in quieting technology for its SSN. The other side of the equation is detection. Can china detect a well handled LA class SSN? Does it possess the sonar suites to be able to do this?

SSK's, even with the AIP, are still very vulnerable due to the fact that they are useless above their 5 knot "quite" speed. At higher speeds, they are noisy, their batteries run out faster, etc. In comparison, the Seawolf has a "quite" speed of "more than" 20 knots, and that is using US sonar suites.

Training and tactics are the other pillar. The USN has been using nuke boats since the 60's. They had plenty of time to home their skills in the coldwar and know how to handle their boats. They have established doctrines and tradition.

With regards to the above and ability/capability issues i remember watching the Discovery channel recently perhaps the article below is informative ...


While they are probably the most capable, certainly the largest diesel-electric (conventional)submarines in the world, massive problems with noise and the weapons software suite resulted in a series of delays. In 2005, it was revealed that the maximum diving depth of the Collins class had been reduced, following an incident in February 2003, when a seawater hose failed on HMAS Dechaineux, flooding the engine room and almost sinking the vessel.[1] The maximum depth remains classified. The government claims that the problems of the Collins class are now solved or on their way to resolution. In a 2003 joint naval exercise, three Collins-class submarines reportedly "sank" two American Los Angeles class attack submarines and a US aircraft carrier, supporting the claims of defect resolution and combat effectiveness.[2]

Re: Chinese sub thread

The following Kockums statement shows us the capacity of the Gotland Class prior to the current US mission. It also gives data on how lethal a SSK with AIP is when it is in the right place on the right time so to say..


"In the past few days, the RSwN submarine HMS Halland (Gotland Class) has swept the board in exercises with Spanish and French naval units in the Atlantic. Futhermore, she also defeated the USS Houston from the USA.

During a sub-hunting exercise, in a “duel” with Spanish naval units, HMS Halland recorded a victory. In a similar “duel” against an SSN-class nuclear submarine of the French Navy, HMS Halland won.

The exercises were carried out in the Atlantic and thereby so-called “blue-water” exercises.

In an additional battle she also defeated the USS Houston, a Los Angeles-class nuclear attack submarine."

I found this working-paper on the net for all you interested. Surely you all read it already and will curse me for wasting your time.

Thanks for posting that information. As for that link. That sucker long. Believe it or not I've read a lot of that previously. But did find some new info. It is very interesting nevertheless.

I've always said that the USN was good at posting what I call 'happy news"..That's a fact. I know I lived it.

I'm going to search for info on the USS Houston to see what the USN spin is on the situation. Betcha I can't find anything.

Well I did. The USS Houston was in a excersise but the USS Houston is homeported in Guam and the excersise was with the Austrailans...Humm? How old is that article Mazepa? This story is from the navy.mil. dated 10/18/2005. I know the Houston is still in Guam because it moved their eairler in 2005 to repalce the USS San Francisco. Anyway like I said this article is just 'happy news" No real news...

USS Houston Strengthens Warfare Capabilities
Story Number: NNS051018-15
Release Date: 10/18/2005 10:11:00 PM

By Lt. Arwen Chisholm, U.S. Naval Forces Marianas Public Affairs

SANTA RITA, Guam (NNS) -- The nuclear-powered attack submarine USS Houston (SSN 713) partnered with the Australian Navy in September to strengthen its warfare capabilities through an annual joint exercise, Lungfish 2005.

Lungfish 2005 is a tactical development exercise between the two navies that trains and teaches tracking methods of both nuclear and diesel submarines.

In a direct response to the U.S. Pacific Fleet’s priority to enhance anti-submarine warfare abilities, the submarine’s crew participated in two anti-submarine missions and joint submarine command courses while deployed to Perth, Australia, this summer. The joint exercises allowed for the U.S. Navy to learn and gain knowledge from the Australian diesel submarine HMAS Farncomb (SSG 74) and one of the country's nuclear submarines, HMAS Rankin (SSG 78).

“We tracked their submarine and tried some tactics out to enhance our ability to track and detect a diesel submarine,” said Lt. Cmdr Brian Davies, executive officer of Houston.

While both navies conducted tracking and detecting exercises, three Sailors from Houston were afforded the opportunity to ride aboard Australia’s diesel submarine.

“She is a pretty new submarine, totally automated with computerized systems, different from our boat,” said Machinist's Mate 2nd Class Thomas D. Douthitt of Grand Prairie, Texas, who participated in the exercise from inside the Australian diesel submarine. “Ours is manual. Everything is done by us mechanics.”

According to Davies, the exercise provided both navies hands-on, real-time training, which is more effective than any teachings conducted by a simulator or trainer.

“You can sit in front of a trainer all day long, but it is just different when you have a real exercise, a torpedo in the water, and getting a chance to see how you perform under pressure,” he said. “Any chance we have to go against a real diesel boat is beneficial to the U.S. Navy.”

In addition to the skills developed, the weeklong exercise strengthened communication ties between the two allied countries.

“They aren’t that much different than us,” Douthitt added. “We are all submariners. We all have the same ideas, same beliefs, but we say it different. They are all brother submariners.”

Houston, a Los Angeles-class submarine, is homeported in Apra Harbor, Guam. It is designed to seek and destroy enemy submarines and surface ships. Its other missions range from intelligence collecting and Special Forces delivery to anti-ship and strike warfare.

Re: Chinese sub thread

I think the statement from the Gotland class contructor Kockums was from 2000 due to the use of HMS Halland. So its not smoking news from the press so to say :)

The thing that struck me as quite illogical is the use of NAU on submarines doing exercise with the USN. Is it common practice to enhance the signature with such a device and how does the USN justify the use? I thought that training was done to learn and find out if system works as they are supposed to do in real-combat situations. Surely the foes of USA will not bring their NAU:s in combat to help USN to find them....

Mazepa you are so right! The enemey is not going to bring anything with them that would help find them. So many of these excersise are just that. Excersises. The results are sometime known before the "excerise" begins. I'm just happy that some US "allies" have desiel boats.:) Because my good old USN that I love so much can't find a desiel boat. Nobody else can either....

Re: Chinese sub thread

I'm pretty shocked that the Australian sub managed to sink an aircraft carrier !

Wonder how that would work with a Sunburn ?

No you're not. That's just sarcasm. Much like many of us in this forum. Myself included.:p

That's an intresting idea about the Sunburn. Can it be launched from under water? I don't know. I'm sure it would take a speical version. And if launched from underwater would it still atain the same supersonic speed?

Re: Chinese sub thread

poeye, a popular method for launching anti ship cruise missles for china is to seal the missle in a tube. the tube is fired out of the submarine, and rises to the surface. it breals open and the missle flys out. this has already been done on for the yk-82, and may work for a moskit.

Thanks Miggy..I learn something new everyday. I'm not sure what method the USN uses and I'm not going to look it up. I just know they can do it.

The Sunburn in desiel boat would be a formidable weapon. Devestating!

Can the Sunburn fit inside a torpedo tube. Those are not exactly small missiles.
