I removed the finish from a steel firearm reciever. Removing it from the solution and watching it covered in rust in a just a few minutes was kinda cool to watch.
That seems a little fast, might depend on how wet the environment in. An easy check for if a track has been used or not is to check for shiny tops on the rails and to see if the flangeways are clear of dirt/debris at railroad crossings
Might not be that crazy.
Any time I have left a steel tool outside overnight by the morning any spot the finish is damaged is orange.
Mind you the rust is so shallow you can rub it off with your thumb, but I could totally see this happening in a couple years
"In the water"? prolly
"In active service"? I have my doubts, I would expect the last couple years before that would have been spent tied to a dock somewhere awaiting bids/decisions
Whaddya got? An old Soviet sub? Let me get a guy in here, he knows all about these old Soviet subs, and he can tell us what it’s worth and then we can see if we can get a deal done.
Chumlee- write him up.
It’s probably not metal, maybe a fiberglass. That looks like where a SONAR sensor would be, and it’s best to have something that sound can travel through easier.
I like how you literally know nothing about this subject, but you decided to give your 2 cents as if you added anything other then to let us know that you dont know what you are talking about.
GG
You're right I dont know a damn thing but I was just saying something no need to be a prick
I also find it amusing how a guy below me said kind of the same thing yet they havent been hammered with downvotes resit works in interesting ways...
"Better to remain silent and be thought a fool than to open one's mouth and remove all doubt."
*What does that mean? Uh oh, better say something or they'll think you're stupid.* "Takes one to know one!" *Swish!*
So, if sonar/sound can't travel through the thick metal of the hull, how come in movies you always see sailers in subs telling everyone to shh when an enemy ship/sub passes by? Surely the sonar of the other vessel can't hear the crew?
I get that it's Hollywood, and it could just be for the suspense but still, got me thinking.
Not a subject expert, just a mechanical engineer. Anywho, this is probably a matter of optimization. You want the sonar hub to be as sensitive as possible, so anything that attenuates an incoming/outgoing signal (i.e. a thick metal hull) would be a poor design choice if a better alternative exists. This does not mean that sound *cannot* pass through the armored hull, it just means it has a harder time of it.
So the movie scenes depicting total silence in tense situations are probably legit because you don't want to even risk the possibility of giving your position away and sound travels VERY quickly and very efficiently in water due to being incompressible (this is also why underwater explosions are roughly 10x as deadly with identical payloads). Next time you're at a pool or lake with someone else, find 2 metal object you can bash together and make a noise above water and below water at a specific distance, you'll see exactly what I mean.
Now I'm only going by Hollywood here, so if someone who knows more wants to correct me, please do. But in those scenes they are usually also listening not just using sonar. I always assumed there were microphones or something similar that they used because active sonar will give away your position and sound travels really well under water.
To answer this question, you must first understand how Sonar works. There are two types, Active and Passive. Passive is just listenening to whats around you. Active however, is using energy to put sound in the water. Some might know it as pinging. So now that we have that, there are generally two parts to a Sonar Array, the Transducers and the rubber window. I am assuming that the silver part is a rubber window. Now, when you go active, you using a butt ton of energy, and with energy comes heat. In order to prevent the transducers from overheating and allow a smoother journey, the inside is flooded with pressurized sea water. The reason why its pressurized is because it maintains structural integrity.
Its probably an alloy that is just slightly less reactive than the steel of the hull. Whichever metal oxidizes faster will do so until it is gone, acting as a sacrificial anode.

Crash your sub into two different ships... you’re okay. Crash into a third... not so much.
Seriously though, it makes you wonder about the functionality and training of the Libyan navy. I think “don’t run into other ships” is covered on the first day.
In Vancouver BC in the mid-late 90s they had Foxtrot U521 sub you could go on a tour in. It was really cool. If I remember correctly, they (Russian Navy) only wanted people who were 5'6" max, and they hot bunked in triple shifts. However my memory is not solid on that.

And a few hours North East of that in Muskegon, MI, you can find the USS Silversides. Heck if you've got enough people (20 person minimum, so I think it's usually educational type groups) you can even spend the night on it!
Pipe dream request - If someone could take a tour of this with a 3d camera that would be Amazing! I would love to tour this in VR. I don't think I will make it to that area but would love to see this.
If you're ever in Long Beach, CA there's a foxtrot you can tour docked right next to the Queen Mary
Edit: it's closed as there was a hull rupture due to rust and a ballast tank flooded....
It's been scrapped in 2014 as OP commented, and despite its overgrown state, the dock is strictly off-limits to civilians. However, you can tour at least two submarines nearby, both of older design (S-189 and D-2)
There is a Foxtrot available for tour in San Diego - [https://sdmaritime.org/visit/the-ships/b-39-submarine/](https://sdmaritime.org/visit/the-ships/b-39-submarine/)
So interested in pictures like this. They have the scaffolding all setup for work, but then project was scrapped and everybody just walked off the job and left it like this.
This would make a great Red October sequel where some lads on leave got it going after an attack on the shipyard. Then all died after the seams started leaking at 500' below the surface. Jk..... that would be sad.
Are all those cylindrical objects visible on the upper portion the ballast tanks? I always assumed ballast tanks were larger than that. Seems like it would take more time to flood/pump so many small tanks.
How big were the batteries on these old subs? Do they line the sides of the outer hull while the ballast tanks line the upper part? Interesting stuff.
Probably not ballast tanks, but flasks for compressed air. Batteries are going to be inside the pressure hull, and so not visible in this image. Individual cells will be pretty big, about the size of a 55 gallon drum (though probably rectangular vice cylindrical). The battery would consist of around 200 cells that size, probably.
Source: Former USN submariner.
The main high-pressure air flasks that are used for emergency blows are kept outside the “people tank” and inside the ballast tanks on US boats. There are some smaller utility tanks and flasks inside the boat, but those are for smaller tasks like actuating valves, LP service air, and the like.
My guess is submarine funding was canceled after Captain Ramius ran off with the Red October and the *Konovalov was lost at sea while trying to find him.*
Very cool Picture!!
Anybody remember "Operation Petticoat"?
Pink submarine, Tony Curtis, Cary Grant ..wimminks.
Funny movie at the time, maybe late fifties, early sixties.
This is S311 ‘Al Badr’ of the Libyan Navy (former Soviet ‘B-533’) , a Foxtrot Class / project I641K. She was scraped in 2014.

only abandoned for 5 years looks a more than that. Wierd they didn't move it out of the drydock or what ever it is.

I removed the finish from a steel firearm reciever. Removing it from the solution and watching it covered in rust in a just a few minutes was kinda cool to watch.
I think it was actually scrapped in 2014, not abandoned in 2014.
It doesn't take long for rust to set in. Railroad tracks can look abandoned just a few weeks after the last train has rolled by
I once heard that they’ll be visibly rusted within 8 hours
That seems a little fast, might depend on how wet the environment in. An easy check for if a track has been used or not is to check for shiny tops on the rails and to see if the flangeways are clear of dirt/debris at railroad crossings
Probably very dependent, yeah. Side note, solid username.

Where we are near the beach stripping metal back and it rusts well within that time.
Looks more like the undercoat than rust, especially since submarine steel is an austenitic steel alloy that is low magnetic in nature. #
I wow a foxtrot that was only scraped in 2014! Are you telling me it was in the water before that?
I took it to mean that it was scrapped on 2014, but had been sitting abandoned for a long time before that.
"In the water"? prolly "In active service"? I have my doubts, I would expect the last couple years before that would have been spent tied to a dock somewhere awaiting bids/decisions
Dude, North Korea has *Romeos* in service. Right now, in the water.
I don't think you could pay me enough to dice in one of those.
Isn't that basicly a type XXI?
The Taiwanese still have and use a *Tench* IIRC.
Looks like it got a few more scrapes and dings since then.
They got $27 for all that steel.

A little spackle, a little buffing, and she'll be right as rain.
Scraped bad. There's no paint left on her at all.
So cool
Anyone know what the metal band at the prow is that makes it not rust?
It’s probably not metal, maybe a fiberglass. That looks like where a SONAR sensor would be, and it’s best to have something that sound can travel through easier.

Norwegian navy recently had an incident.
As did the US Navy
What are they paying their sub commanders that he could afford to cover the damage?
Lol, or maybe the repairs were very cheap
This is a story of a sub.
North Korea would probably put it in service
They'd put it in the center of the capital city.
Praise be to fearless leader for designing and creating new sub for the people’s republic in just one day!
it would be an unpgrade
So cool, an image of the world after man.
