其他国防官员说，里根号最近的潜艇遭遇跟2006年中国潜艇跟踪小鹰号航母类似。
在那次事件中，中国的宋级攻击潜艇在鱼雷范围内浮出水面之前未被探测到。

Other defense officials said the Reagan’s recent submarine encounter appeared similar to China’s stalking of the aircraft carrier USS Kitty Hawk in 2006.

During that incident, a Song-class attack submarine surfaced undetected within torpedo range of the Kitty Hawk on Oct. 26, 2006—nearly nine years to the day of the recent Reagan encounter.
