say your nuclear sub is doing its usual things along the enemy costline in case need be to launch nukes, and say the enemy launched a torpedo at your sub and it was sunk.
could you know it was sunk when and where and who did it?

>and say the enemy launched a torpedo at your sub and it was sunk.
Do you know how many submarines have been sunk by torpedos launched by enemy submarines in all of human history?

>could you know it was sunk when and where and who did it?
Only if it was surfaced.
Although I believe they check in at regular intervals.

There was that one German uboat vs american sub if i remember correctly durying ww2 But idr who won that one

Anon as retarded as the frogposter is you're not much better

It was British, but broadly correct. And it was a very unusual kill, requiring manual pencil-and-paper calculation before firing at a target that was employing constant speed and direction.
Torpedos are much, much better now, making this sort of thing much more easy to do. But the fact remains that if something kills a submarine it will almost certainly be an ASW helicopter or ship.
To answer your question, it can recieve orders via extremely-low frequency (ELF) transmissions while underwater, but not transmit them, while submerged. They may have an automated system to raise a buoy that, once at the surface, can immediately notify their country of the sub's demise. Some of the submarine autists on here can tell you more about that.

I assume no but im no expert.

Everyone in the world would know because they'd be a huge racket caused by a submarine getting hit with a torpedo followed by the wreckage hitting the bottom. You wouldn't immediately be sure on who sunk it though but the enemy coasties would be able to find out if they aren't already tracking the other sub.

When K-129 imploded every listening beacon in the Pacific registered it and the US was able to triangulate its position from that data.

>could you know it was sunk when and where and who did it?
Immediately no.
If you were able to rise wreck (year after) you may find torpedo fragments and id torpedo and who made them. It can be spoofed.
It's spooky.

>>63942449 (OP)
>could you know it was sunk
Yes, they come near the surface for two way communication every so often.
>when and where
Hydrophones and last known location would narrow it down a lot.
>who did it
Only nation states have the capability to sink it so that will limit the suspects, combined with satellites recon you would have a pretty good idea.

>>63942456
during ww1 in the adriatic it happened multiple times between austria hungary and italy.

First of all, herbs because frog poster.
Second of all, OP knows absolutely nothing about submarines except what he's seen on TV, assuming OP isn't a bot or a scripted troll.
Third, fuck me because I'm taking bait.

Boomers (aka Chickens of the Sea, aka the big subs that carry ballistic missiles capable of carrying nuclear warheads (among other things)) do not violate the territorial waters of sovereign states. No, really, they don't; there's no reason for them to do so. They can acheive their mission just fine from outside territorial waters, and it would be a nasty diplomatic incident if one were somehow caught inside those waters. If you're going to violate territorial/coastal waters that's going to be the job of the fast attack/intelligence submarines. IF one of those subs was caught, and IF it was torpedoed then command would know immediately. Why? Because those missions are _closely_ monitored by sattellites so that if a surface vessle seems to be getting maybe a little too close for comfort, a separate asset can be used as a distraction. In other words, any counter submarine actions are going to be seen coming a mile away. If those actions actually end up in a sunk sub, command will know. But even if there weren't constant satellite surveillance of the mission (there is); any exploding torpedo will be heard for thousands of miles under water. That sound will be picked up by the underwater monitoring networks (like SOSUS), immediately triangulated, and conclusions will be drawn. And yes, a torpedo exploding is a completely different sound signature that is easily differentiated from an imploding submarine, or an internal explosion, etc.

IF somebody sunk a Boomer outside of territorial waters it would be an act of war which would be answered with "proportional force". The US would probably sink your entire military fleet over the course of 12 hours about 4 days later. Don't touch our boats.
