Where is the propeller ? Was it removed before they dry the dock?

u/Gladius_Illuminatus Sep 24 '22 Silver Helpful All-Seeing Upvote

Yes. They are always removed or covered up. If you know the shape of a propeller you can create a sound signature (what it sound like when moving through the water) for it and then use that to identify/ track the sub based on sound.

They say every submarine can be uniquely identified by sound. I think The Hunt For Red October shows that at the beginning.

u/dvdmaven Sep 25 '22

Speaking as an ex-submarine officer, this is true. No two ships are identical and the reduction gears for the screw (aka prop) always have a small indexing error from the machining. Auxiliary equipment, generators, pumps, etc will have variations in mounting brackets. Even things like the smoothness of the hull can produce a unique signal.

u/ravenwillowofbimbery Sep 25 '22 edited Sep 25 '22

This is interesting and something that I didn’t know. This may seem kind of off topic, but your comment instantly made me think of whales, dolphins, etc. that produce sounds that are unique to each animal. There is probably a lot we can learn from animals who navigate the depths of the ocean through echolocation and “natural sonar” (e.g. beluga whales, etc.). This is all so fascinating. Thanks for sharing.

Edited first sentence for clarity.

u/k1ttyclaw Sep 25 '22

The navy actually tracks individual whales using IUSS. The songs are unique enough The analysts have names for some as they have been tracking them for years

u/Supply-Slut Sep 25 '22 Silver Helpful

There’s whales that live as long as humans, and some much older. They have this complex communication and navigation system they evolved with that humans only relatively recently learned how to use. They’ve been navigating the oceans, 70% of the planet, for longer than our entire human history.

I wonder what their thoughts are like, they are quite obviously extremely intelligent. We wonder what first contact with an alien species might be like, how we would communicate with them, and yet here is a species on our own planet that is clearly intelligent to a high degree and we’ve only just barely managed to figure out that they are communicating at all.

We are the enigmatic alien invaders to them, unable to achieve cross-communication while our species methodically exterminates them.

u/KickBallFever Sep 25 '22

A while back Nat Geo did an article about how human seafaring is causing problems with whale communication and navigation. Basically the noise we make from ships travels for miles underwater and can interfere with whale communication. To whales the sounds can all converge and be extremely loud and disorientating. There doesn’t seem to be enough research being done on this.

The general idea is to make no noise at all, so adding a sound element, while it may confuse an adversary that has a sound profile of your submarine, would simply make it easier to track in the first place

17

u/HorrorMakesUsHappy Sep 25 '22

No, the goal is to dampen all sound as much as possible. If you're intentionally modifying sound with the intention of it being heard you're already missing the main goal - to not be heard.

If I'm a trigger-happy lunatic with a gun who's blindfolded, you don't want me to know where you are at all. Changing your sound might make me think I'm shooting someone else, but if I'm trigger-happy I might just off and shoot whoever I'm hearing. So you don't want to be heard at all.

3

u/SnooHesitations9830 Sep 25 '22

Actually if you dampen the sound too much the other Navy's start looking for the holes where no sound exists. After making this mistake on another sub class they started putting noise makers on them. I was there when this video was recorded.

It's the most secret thing discussed in submarine training besides the reactor. Probably more so, if that makes sense.

Everyone knows the reactor is secret

It makes sense that the charts are secret

I had no idea the screw was secret until i was told.

I read a little Tom Clancy, and I'd venture that mentioning blade counts made the Navy uncomfortable if they were accurate

Unless you are the Captain, XO, Navigator, Engineer, Engineering Chief, Sonar Chief and Head Reactor Tech of the particular boat the prop belongs to, you get within 100 feet of visual range and the guards tell you off unless you have the necessary clearance quals from the contracted company who makes them. Any closer and you're likely to get shot.

Source: served on USS Georgia during drydock periods and even I, with an nsci security clearance, was not allowed to see the prop.

15

u/FlatBrokeEconomist Sep 25 '22

Whoa wait which drydock periods? I was on the georgia too.

Also there’s no such thing as a “head reactor tech” so you must’ve been a coner.

I'd be willing to bet there is a specialized maintenance vessel that will take if off and store it with ease. The USA has a load of these subs and the screws likely end up needing removal,replacement, repair and/or maintenance after so many hours of operations.

52

u/ReactorMechanic Sep 24 '22 edited Sep 25 '22

Normally it's just covered up, but this is a special case. Because the ship is being converted into a Moored Training Ship, they are replacing the screw with a device called a waterbrake. It's going to be sent to the Navy's Nuclear Prototype Training Unit, so the reactor will remain operational to train students in its operation. But you obviously don't want a screw on the shaft pushing the ship when it's tied in one spot. Just leaving the spot empty would mean there was no resistance and you'd never have to generate any power to spin the shaft. So the waterbrake is intended to use the friction of moving radially through the water to provide simulated thrust on the propulsion machinery, so you get useful power out of the reactor plant, but don't actually move the ship.

26

u/SFWusername68419 Sep 24 '22

Idk how you can train people with a water brake. It doesn't simulate that gangsta lean you get when you go fast.

The other person was correct, propeller design is classified so even in the construction phase it's covered after an evening installation. Especially true with the new Virginia class and soon to be built "boomer" Columbia class which is huge and will probably be one of the quietest in existence

u/HorrorMakesUsHappy Sep 25 '22 Helpful

The one piece of information I'd share with anyone starting, wanting to start, or afraid to start:

You'll only change about as much as you want, on how much work you put in.

Some people don't want to change too much, and are afraid therapy will make them change into someone else. Other people feel they need to change a lot, and are afraid therapy won't help them change enough.

The analogy I like to use are the scales on a fish. Our beliefs are intertwined, and when we adjust one, often the ones around it will move to adjust a little. But fixing a misaligned scale doesn't turn a trout into a marlin. If you're a trout and you're afraid therapy's going to turn you into a marlin, it won't. That's not what it's for, and that's not how that works.

If you feel like you have a lot of scales that are messed up and need to be fixed, that's okay too. They can be, it's just going to take some time, that's all.

And if you're a marlin who's been pretending to be a trout this whole time, the therapist's job is not to tear down your trout disguise. Your therapist's job is to help you reach whatever goals you set. If your goals don't include tearing down your trout disguise then just tell them that. If you don't feel you can trust your therapist (maybe they're a friend of the family or something) then that's a different issue - not with therapy, but with that person being your therapist. Find one that's an independent third party you can trust.

And if your problem is that you can't trust anyone, well ... that's actually something you'd need to talk to your therapist about and work through with them, because that itself is probably a misaligned scale that needs to be worked on.

My dumbass initially thought of this taking place underwater so it was amusing picturing people in diving gear for some reason walking across a wooden plank and still having to not look down sdfhklfjsh

Guess it moved. Been a while since I worked in the dry dock in portsmouth. Thanks for the update.

u/zxcoblex Sep 25 '22

Yeah. The Navy has two places they train nukes on real reactors:

Nuclear Power Training Unit (NPTU) Charleston, SC and NPTU Ballston Spa, NY.

Charleston has two old subs tied to a pier in the river.

Ballston Spa has two land based plants that are designed to look like subs (well, one and a half are anyway).

Is it an upmarine now?

So that's what that place in San Fierro docks was for.

u/squirrelsgravy Sep 24 '22

I work there !

u/f38stingray Sep 24 '22

I think it's kind of interesting that it's now referred to a "ship." Like submarines (even huge ones) are usually known as boats. I guess only in death (or retirement) do they have the honor of being called "ships."

Why did they name a sub after La Jolla, CA?

u/k1ttyclaw Sep 25 '22

LA class subs were named after American cities

Fun fact: there are more airplanes in the ocean then submarines in the sky.

I’ve been on this submarine. My stepfather was the chief of the boat in mid 90’s

u/The_good_fixer Sep 25 '22

I worked on the MTS design, the whole topside decking package, Roughly a year or ~2000 hours of 3D modeling with the assistance of a really extensive music collection and probably 75gallons of coffee. Still haven’t seen it in person which is disappointing

This was at Norfolk Naval Shipyard (NNSY) at Portsmouth, Virginia
(not to be confused with Portsmouth Naval Shipyard (PNSY) at Kittery, Maine)

Preparation
Drydock Flooding
Towing/Tugging (facing the caisson*)
Towing/Tugging (view from the sail of the boat)
Towing/Tugging (view from the head of the drydock)
Draining the drydock (this post)

*the caisson is the big floating gate that settles at the mouth of the drydock

Note: there's quite a few more neat timelapses on that NNSY youtube channel scattered among the awkward PR stuff

u/Proud-Weird2420 Sep 25 '22

Was stationed on the U.S.S DIXON (AS37) and on the U.S.S MCKEE (AS41) submarine tenders, and loaded many torpedoes onto the USS LAJOLLA. Good memories great times!

u/masterkorey7 Sep 25 '22

Used to work for PSNS, was always cool to see the drydock drain in person.

u/sirevidence03 Sep 25 '22

I worked on a dry docking ship. Those were some long days

u/MoreGuitarPlease Sep 25 '22 edited Sep 25 '22

That was my boat! Nuke late 80’s. It was an”show”boat before i got there. When I was there, we went to dry dock and that was miserable. Sea trials were fun after though!

u/Phybre_Awptic Sep 25 '22

This video was from 2015 but the ship didn't leave Norfolk naval shipyard in 2021 to go down to goose creek south Carolina. Super cool and extremely difficult project. Source: I'm a nuclear engineer that works at NNSY

I notice the water pouring out of the side of the sub. Is it for cooling? Is this ballast dumping?

u/AltoRhombus Sep 24 '22

Ya just the ballast water draining

u/zxcoblex Sep 25 '22

We always called it HonoFrisco because the cone was from the Honolulu.

2

u/Sorenchu Sep 25 '22

Indeed the Honolulu was incorporated with the good boat san Fran. We also had the Memphis's fair water planes and countless other cannibalized parts throughout. The LA class is getting old... we took what we could get. That nose job we had gave us a good shake at speed lol

I’ve worked these dept . Directly on these components the prop . It’s def . Covered up and secret other than install and uninstall . Like others have said . They don’t want the pitch and angles known for each individual sub because of sonar and radar frequency
