Reuters said a Chinese submarine stalked a U.S. Navy aircraft carrier battle group in the Pacific last month and was undetected until it surfaced within firing range.
The Chinese Song-class diesel-powered attack submarine was seen within five miles of the carrier Kitty Hawk and its accompanying warships on October 26, the Washington Times reported, citing defense officials.
The surfaced submarine was spotted by a routine surveillance flight by one of the U.S. carrier group's planes, the report said.
Disclosure of the surprise encounter comes as the commander of the U.S. Navy's Pacific Fleet
, Adm. Gary Roughead, was making his first visit to China which began over the weekend, The Washington Times said.
