A Chinese submarine stalked a U.S. aircraft carrier battle group in the Pacific last month and surfaced within firing range of its torpedoes and missiles before being detected


The sub, a Type 039 Song-class diesel-electric boat, is one of the Chinese navy’s newer models, designed and built in China. China also operates Russian-built Kilo-class diesel subs.


China’s military build-up, and naval build-up in particular, should concern us. And within the naval build-up, the obvious strategy to heavily utilize submarines should be very troubling. The use of subs, especially ultra-quiet diesels, will threaten our carrier operations as this incident demonstrates.


Assuming this report in the Washington Times is accurate, a very loud wake-up call has just been sounded. Carrier groups operate with a nuclear attack sub, and the fact that this diesel snuck in under our noses is telling.


There are two things here that need to be noted.
First, plans to greatly reduce our attack sub fleet are misguided.
Secondly, we need to become more adept at tracking (and therefore attacking) diesel-electric subs.
