"American military chiefs have been left dumbstruck by an undetected Chinese submarine popping up at the heart of a recent Pacific exercise and close to the vast U.S.S. Kitty Hawk - a 1,000ft supercarrier with 4,500 personnel on board.
By the time it surfaced the 160ft Song Class diesel-electric attack submarine is understood to have sailed within viable range for launching torpedoes or missiles at the carrier."

"One Nato figure said the effect was "as big a shock as the Russians launching Sputnik" - a reference to the Soviet Union's first orbiting satellite in 1957 which marked the start of the space age.

The incident, which took place in the ocean between southern Japan and Taiwan, is a major embarrassment for the Pentagon."

"Analysts believe Beijing was sending a message to America and the West demonstrating its rapidly-growing military capability to threaten foreign powers which try to interfere in its "backyard"."

I think SAM already posted this somewhere. It happened a year ago.

Diesel-electric submarines are extremely quiet subs. Unless the carrier group was using active sonar, then they shouldn't have been surprised at all. Any surprise would have been that they could have stayed submerged long enough to get within that range ...lack of oxygen, and a build up of carbon dioxide for the crew, if nothing else.

Electric subs are the epitome of quiet.

The millitary will say ANYTHING to get more and more of our money. If we include all security (police, FBI etc... it totals something like ~20% GDP, the same % as what North Korea, a police state, spends.

I see this is another tactic to keep the juice flowing.
