The U.S. has approximately 70 submarines, whereas the ocean is literally enormous. They can’t possibly defend the entirety of American AND foreign waters with a mere six dozen subs, because an enemy sub can just slip right past them. What am I missing?
>an enemy sub can just slip right past them
your premise hinges on a misunderstanding which is yours by virtue of misinterpretation or because you listened to a moron at face value
what exactly do you think the mission of a submarine is? they don't form continental picket lines.
Well if submarines can travel under floating warships undetected, then it seems like the only thing that can defend against them is another sub. If your subs are spread out so thinly, what’s to stop a hostile sub from creeping right up to the shore of a major coastal city?
>Well if submarines can travel under floating warships undetected, then it seems like the only thing that can defend against them is another sub.
there are tons of weapons and sensors that are used in anti-submarine warfare. Destroyers and helicopters work together to comb the sea with sonar and drop accurate depth charges on enemy submarines during wartime. In fact, other submarines are probably pretty shitty for this purpose.
>sonar
I thought most modern submarines were relatively soundproof and thus impervious to sonar?
Sonar and signal processing tech has advanced just as steadily - probably more so.
but if it WERE the case that submarines were invisible to sonar, then how would one sub find another anyways?
drop a buncha bombs everwhere
>but if it WERE the case that submarines were invisible to sonar, then how would one sub find another anyways?
Looking out the window?
the sound of drawing the curtains would be audible on sonar, moran.
Shit dude, come on. There are two types of sonar, passive and active. Passive is just a microphone that listens to existing sound in the water, whether that's the screws turning, motors running or launch transients from torpedo tubes. Active sonar on the other hand is echolocation, not unlike what bats use to navigate caves in total darkness; you send out a pulse and listen to the echoes to see if there are objects in the water.
Man made objects always make some sound, so it's impossible to be completely silent. And if you're a hunk of metal in the water you're going to have a reflection regardless of all the anechoic tiles you have attached on the skin. If you're too close you're going to be found.

another misunderstanding
Is this a board for 10 year olds?
Yes. But that's a different topic
Summer /k/ us a perennial thing, newbies.
local subhuman has absolutely no idea how subs work but still makes a thread about them
Is this a new shit skin cope?
“USA only had 70 subs and has too many naval ships”
I'm English you speak my language and stuff
Go pay the telly tax, Nige
we have these things called spy satellites, they find the ships and direct the subs onto their targets
i suggest you get on wikipedia and start reading
This. Start here: https://en.wikipedia.org/wiki/SOSUS
Damn homie that shit so sus no cap
Networked intel from external assets such as satellites, surface vessels, sonar buyus or MPAs. Also, sound carries for a long distance in the water and onboard and towed arrays are quite sensitive.
There's also the DoE gay that posts here saying he's working on using SAR to track submarines from space by finding and analyzing the wakes.
lurk moar homosexual
>What am I missing?
You're missing that Submarines aren't the only ships in the US Navy, and that the US has partner/allied nations who also do naval patrols or whatever the Navy calls it primary mission. You're also forgetting that ships and planes have radar/sonar to detect submarines.
Additionally we don't defend every drop of water because not all of it belongs to us or our allies or is considered an important place to be.
>Additionally we don't defend every drop of water because not all of it belongs to us
That's not very Pax Americana of you
What if the U.S. like, tracks foreign navies and sends subs and ships there when needed
Do you think that ships defend something by physically making a big wall with their hulls that you can't drive through?
U-864 is the only submarine ever sunk by another submarine while both were submerged, its not really a core requirement driving submarine design nor a standard approach to ASW.
oh my frick you are moronic
The US knows where most if not all enemy submarines are based and either has a sub waiting for the enemy sub to come out or waiting at a large number of ocean choke points that other subs have to pass through. Plus a lot of patrol planes.
No since subs could snorkel and torpedos could be guided the best way to hunt and enemy sub has been with another sub. Look into the development of the 688 class, Seawolf, Serria, and Akula subs. Also the MK-48 ADCAP.
Correct
Listen here you dimwit. Approx 1/3 of US submarines are for the express purpose of putting a continental sized curtain of nuclear fire anywhere we want with about 45 minutes notice. 1/3 of US submarines are for the other purpose of preventing any other country including our allies from doing the same and 1/3 are just to swing our dick around.
>1/3 are just to swing our dick around.
Or if you particularly hate the US, to surface directly underneath boats full of schoolchildren. Which I suppose is the same thing in the end.

Would you want to frick with the US after seeing that?
They aren’t spread out evenly.
Jesus frick the war tourists are getting dumber.
