Navy confirms Chicom sub was not detected

Bill Gertz:

Navy officials confirmed yesterday that an aircraft carrier battle group failed to detect a Chinese submarine that surfaced within weapons range of the USS Kitty Hawk. Anti-submarine defenses for the carrier battle group will be reviewed as a result, they said.
"It was not detected," said one Navy official of the encounter with a Chinese diesel-powered attack submarine. "And we're concerned about that, obviously."
The Chinese Song-class attack submarine surfaced near the carrier in deep waters off Okinawa on Oct. 26. It was armed with wake-homing torpedos and anti-ship cruise missiles.
The officials said it was unusual for the submarine to be operating in deep ocean waters, but the incident was not like the April 2001 collision of a U.S. EP-3 surveillance aircraft and Chinese F-8 jet that ruptured military ties.
"We were operating in international waters, and they were operating in international waters," the official said. "From that standpoint, nobody was endangering anybody. Nobody felt threatened."
However, other defense officials said the submarine surfacing was a provocative action by the Chinese military, which has placed a high priority on practicing anti-aircraft-carrier operations against U.S. carriers and warships in preparation for a possible future conflict over Taiwan.
The carrier was not engaged in anti-submarine warfare exercises at the time and thus did not have active patrols for submarines, the Navy official said. As a result, submarine defenses for the carrier and its accompanying warships will be reviewed, he said.

The suggestion that the sub surfaced after being detected is apparently wrong. It appears taht it surfaced to make a point. It could be a costly point since it will make US forces more vigilant in the future.
