But since neither country is currently involved in a shooting war, don't ya think it would be a good idea to hit the 'off' switch on that shit? Or at least honk your horn?
“One if by land. Two if by sea”
Is it possible that they were being environmentally sensitive and not using their best sonar to avoid offending the sea people.
Boomers aren't there to fight shooting wars. Boomers are there to deter nuclear attack by Russia or China.
Once a boomer has to fire its missiles, it has failed its primary mission of deterrence.
A boomer is effective only because its location is not known and, thus, a Russian attack on France or Britain results in Mutually Assured Destruction. Once you make your location known to the French or Brits, chances are you have made your location known to the Russians and the boomer has lost its deterrent power as it can be killed by a Russian fast attack sub prior to a Russian nuclear strike.
Not for these guys. They are boomers, nuclear missile submarines. Their job is to make like a hole in the water, waiting for the command they all hope will never come.
If they turned that stuff off, not there likely is any "stuff" other than good design, then the bad guys could locate them and take them out, then attack their countries.
