Pentagon: New Class Of Silent Submarines Poses Threat
POSTED: 6:54 pm PDT October 19, 2006 UPDATED: 6:15 am PDT October 20, 2006
SAN DIEGO, Calif. -- The Pentagon said it believes the greatest undersea threat facing the U.S. Navy since the end of the Cold War has arrived.
The threat involves a new a new class of silent submarines -- subs that the U.S. Navy is having trouble finding under water. In this exclusive investigation, NBC4's Chuck Henry looked into one of those submarines in San Diego.
Following is a verbatim script from the on-air report.
CHUCK HENRY: The threat is real. And it has the Navy so concerned that it's turning to Sweden for help. That's because the Swedes have those silent submarines.
And right now, one of them is stationed at Point Loma. Earlier this month, NBC4 had unprecedented access to the Swedish sub and its crew.
What NBC4 aired few people have ever seen and certainly not in the United States.
On the surface it looks like any other submarine, but the U.S. Navy said it could be the most dangerous sub in the world.
FREDERICK LINDEN: Being noisy is something that is dangerous for us.
HENRY: Fredrick Linden is the commander of the HMS Gotland. He and his crew of 29 call the sub base at Point Loma home. They came to San Diego because the Navy is worried about this new generation of silent subs.
The Pentagon leased the Gotland for one year, but now has extended the lease for a second year, as they try to learn why this submarine so difficult to find underwater.
Subs have always had two weaknesses: they make noise and can't stay submerged very long. But the Gotland runs on a high-tech system called Air Independent Propulsion -- or AIP.
LINDEN: With AIP, I can stay submerged for weeks.
HENRY: Not only can the sub stay submerged for up to a month, the AIP technology also makes it quieter than other subs, and almost impossible to pick up on sonar.
When the Gotland wants to be silent and undetectable, especially along coastal waters, there's not a place it can't go. And that's one of the reasons it's here.
Since last summer the Navy has spent months playing a game of cat and mouse with the Gotland off San Diego, and time after time the Swedish sub has eluded its pursuers.
HENRY (TO COMMANDER): As an adversary, how good are you at what you do?
LINDEN: Very good.
HENRY: Can you tell us about your accomplishments?
LINDEN: We are satisfied with being good.
HENRY: According to Swedish newspapers, in training exercises the Gotland has sunk our most sophisticated nuclear submarines. But perhaps even more disconcerting, it reportedly sunk our largest aircraft carrier, the U.S.S. Reagan.
NORMAN POLMAR, NAVAL ANALYST: She's really run rings around our carrier groups.
HENRY: Norman Polmar is a military analyst specializing in naval intelligence. He says since the end of the cold war, funding of the navy's anti submarine warfare program has been scaled back dramatically.
As the U.S. funnels billions into the war on terror, countries like North Korea, China and Iran are building or trying to get submarines like the Gotland.
Two months ago in the Persian Gulf, Iran tested a new anti-ship missile fired by one of its subs.
If the Iranians are successful in getting a Gotland-class submarine, it could pose a new silent danger to vital oil tanker traffic in the region.
POLMAR: With more of these submarines being bought by countries that don't particularly like us, Iran being a good example, yes, there is a potential. There is a threat.
HENRY: And the commander of the Gotland knows just how vulnerable the United States could be if a sub like his fell into the wrong hands.
HENRY: If you look at our coast, North America, is there any place that you can't go?
LINDEN: No.
HENRY: No place?
Linden then shakes his head.
HENRY: Although this emerging undersea threat is a top priority for the U.S. Navy, the U.S. is committed to its nuclear submarine force, and has no plans to develop subs like the Gotland.
The Navy says it just wants to know how to detect and kill them.

Don't the Russians also have a hard to track sub??
I'm skeptical...
Its called the Kirsk, damn near silent.
The news package alone, which I saw on MSNBC this morning, was scary enough.
This is serious stuff.
And Norman Polmar is a guy to listen to. He's smart and a no nonsense kinda guy.
I am sure we'll adapt our boats to counter this threat. Question is when?
Russia also has a supersonic torpedo and plasma stealth for it's aircraft.
Their Kilo class boats are hard to track,but the Gotland is superior to it in most respects.But even the Gotland is being relegated to the background as Germany,France & even Russia bring out new SSK designs with more effecient & higher endurance AIP modules than the Gotland's liquid oxygen/diesel system.
sceptical of??
WARNING! WARNING!
Don't be. Diesel electric subs on batteries are notoriously hard to track because there is almost nothing putting out noise, the only way to passively track submarines. AIP subs are just as hard to track for the same reason, and add to that their underwater endurance is counted in weeks and not days. The sub that's quieter is the sub that wins, nuclear or not.
Now bear in mind this a technologically advanced sub from a highly industrialized country manned by a skilled, professional crew. And I cannot emphasize the quality of the crew enough, the best sub in the world is worthless if you put a bunch of amatures onboard it. Having Gotland on hand is an excellent idea for training, because if you can beat them then you have truly beaten the best at the business with the platform you're training against.
I understand that acoustics are still the primary means of detection. But, don't we also now detect magnetically...and via ultra-low frequency acoustics (subsonic physical disturbance)?
Paging Commander Bond! England needs you to steal the Stromberg submarine tracking system!
