UPDATE: reader Charles points out this report is a replay, not original reporting:
Apparently the story is a mistaken rerun of a 2006 incident… here the scoop…
I’m not sure why this penetration was surprising. The Song class diesel-electric subs are extremely quiet. As are the Australian Collins class subs. That is why the U.S. Navy exercises regularly with the Aussies [and why the U.S. supplies top of the line U.S. electronics to Australia - the only such nation to have access to the U.S. technology].
At least one Australian submarine has already successfully demonstrated just such a penetration capability during joint exercises. Excerpt:
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.
According to senior Nato officials the incident caused consternation in the U.S. Navy.
The Americans had no idea China’s fast-growing submarine fleet had reached such a level of sophistication, or that it posed such a threat.
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…
