Food is the limiting supply on a nuclear submarine I’ve done a 72 day patrol and I know of a couple of 150++day patrols on “special boats” and the USS Pennsylvania did a l o n g patrol
Eventually, it will have to go in dry dock. Sea animals will begin to cling to it. Thus, a sub must leave the water at some time. A nuclear sub can remain underwater (due to it's oxygen generating capability). But, it must leave for the dry dock at some time. This is true for all ships.
In the strictest sense, 20 plus years for nuke powered subs. If it weren’t for the need for food for the sailors, indefinitely, till the reactor needs refueling, possibly never.

😂😂😂😂😂 Look up at other reply ☝️ Walter snerkle🤭🤭🤭
They can stay underwater for years... Some from WW2 are still down there, lol.
Yep rotting away 👍
Hehehe... brilliant comment @Tom Winchel 😄

Replacing batteries with hydrogen fuel cell will be a good option
You still need oxygen (ie air) for the hydrogen to burn.
@@MarkYeung1 that can be carried in a separate tank. Hydrogen has a higher energy density than any other fuel
How about the German style fuel cells AND the lithium batteries that the Japanese are using?
AIP system best for diesel subs.
Thanks.
How long can a submarine stay underwater? what a question !!! the answer is very simple for as long as there is enough food .and of story .
Background music name pls?
Even I wanna know
Cheel, kurt
what is the largest submarine that was ever made?
Titanic
It can submerged and never surfaced
@@rosalynmatanguihan9246 best joke ever 👍
@@rosalynmatanguihan9246 dark😹
class I140 of IJA, if you consider Nuclear Sub then it’s Russian Typhoon class
Russia Typhoon class
Sub can stay under as long as it has food
Submarines feed on large fish

"How long can a submarine stay underwater?"
Ummm.
Forever if something goes really wrong.
What about the Turtle used in the American Revolutionary War??@!!!?!?!?!??!?!?!?!?!!!!!!
Good luck Russia 🔝
They'll be fine I'm sure.
How long can a kilo submarine stay underwater?
Forever if they sink.
Forever if they just had an endless supply of food:)
Who else has notice the voice on this channel has changed recently?
hmmmm why not produce oxygen under water and pass it to engine for combustion
Safest place on earth during ww3 =sub
不思議なのが水中で見付からない様にエンジン切り静かに(留まる)それでも静かに沈むよね❓静かなモーターで海水を(出-入)する❓⭕２日ジ～としてたら🤣(前～後)(左右)傾いて来るよね❓---素人考え🤔Ai---昔の無い頃--
Bis es nichts mehr zu Fressen gibt - noch so eine dumme Frage bitte?!
It takes a special person to do that type of duty, I'm good, I'd rather ground pound all day!
I was in the Navy, spent a few hours in a submarine and noticed it starting to close in on me a bit.
No thanks. No sewer pipes for me.
@@abrahamdozer6273 🤣🤣🤣
your voice changed
For sure the battery technology will get crazy good. Maybe even compete with the Nuke.

Russian submarines can stay for years in underwater...lol..dont look at american side...outdated information 🤣🤣🤣
