If the U.S. Navy were to engage in a battle against the PLAN, the CBGs would be in the bottom of the Pacific Ocean. It is a harsh reality no USN admiral would want to face in the event of a Sino-American nation-state conflict.
Their relatively low cost can make it easy for 3rd world nations to acquire these deadly weapons that could keep CBGs at bay. It is a highly effective weapon that delivers a big bang for a moderate sized buck.
The Fasthawk would have been far superior to the triad of ASCMs aforementioned above had it entered service.
An expert (which I am not, of course) could list dozens of weapons which "are capable of obliterating a CBG."
But for every threat there are countermeasures, some visible and well-known, others not so.
And where there are no countermeasures today, you can be sure work is ongoing in labs across the country.
And there is a pretty simple measure to determine if our countermeasures -- all considered together -- have been effective.
The measure is this:
Considering that military weakness invites attack, how many and what kinds of attacks have perceived weaknesses of US naval vessels invited lately?
