"Aren't our nuke subs noisier than the opposition's conventional subs?"

Not from my training and experience. Our subs are VERY quiet, too quiet for our OWN sonar if they are running deliberately 'quiet.' They do that any time they are in tactical combat.

But sure - if they are doing 'flank speed' underwater, they do make a whine that is audible - IF your ship is listening with the right equipment (rarely done continuously.) But, you won't find any sub captain doing flank speed in most combat situations - because he knows he would be a fool to do so.

Noise created by a sub is not even part of sub detection now-days - surface ships worry far more about temperature layers beneath the surface that bend sound waves - and even hide subs altogether - for long enough to 'get away.'

Why bother to repeal DADT if you're going to scrap submarines?

You’re only saying that because they’re [old joke omitted to avoid getting banned].

Is the FleetASW base still around in San Diego?

Hey guys, thanks for the info.

I’m glad to know how that ping thingy works. I think my pings here on FR are broke, sometimes, LOL.

Seriously, the only thing I know about submarines is what I’ve read in novels or seen in movies. (Yeah, I know - great source for factual info, right? LOL)

I love stories about subs. That started when I was a teenager and read “Run Silent, Run Deep” and “Up Periscope”.

And one of my favorite movies is “The Hunt for Red October” with Sean Connery.
(here’s a trailer if you haven’t seen the movie)

(Of course, I haven’t seen or read any Tom Clancey stuff that I didn’t like, heheh.)

;^D

It’s there for Surface ST’s and Coast Guard. All Submarine schools moved back to Groton in 91-94.It’s a shame too, one of my Favorite things about PCS orders to a school in San Diego was the drive there from Groton, and a stop at the Big Texan in Amarillo.
