Not to be snippy but if that was the case there wouldn't be different levels of readiness in surface in submerged vessels. There is no way peak efficiency can or is maintained at all hours and at all times.
Will you in peacetime compromise your data gathering capabilities to gain information that is clearly not critical for current survival? I hope that makes my original intent with that statement clearer...
so you could probably enlighten me as to if or how many torpedoes/cruise missiles are kept in tubes during regular peacetime deployments.
Sure but if the primary method of detection is acoustic how much does it help if you can change your metabolic ( if you will) rate?

Shades of James Bond.... If one suspects they are being tracked in peacetime the last thing you do is change your performance parameters so the enemy can record even more useful data.

They can already maintain a stationary position, even in the littorals, especially the Virginia class.

Well if you ask me.. I'd say that they messed up with the picture.. Don't think that 4th picture is 971 akula /ii class. It looks like earlier version maybe even a diesel sub...
Orangetom, i have been reading some of your posts. Can u please stop
behaving like a ..... In every post you write, about half is all about how
secret your information is, how well you know everything but you cant tell
blah blah. We all must think harder, "outside the box" etc..LOL. Who do you think you are dude? If you have so much information about submarines, wtf are you doing on this forum? Stop putting yourself above other forum members, seems to me you are not here to learn or discuss, you are just here to brag about your top secret knowledge..blah
Oh..also agree with you...I too noticed it was missing the usual drydock connections in the photos. I dont even see any ventilation or air manifold connections, temporary lighting etc.
The photo on page 1 of this thread. The one with the top of the boat covered in snow and the door opened on the hull. Looks like part of a torpedo loading access door to the inner hull. I am asking myself ...how much noise does a door like that make at substantial speed? On these types of boats with large sails..doors in the side of the sail....same thing. How much noise at speed?? Or do they actually make that much speed?? This is a 12,000 plus ton boat..
My guess she has just been rolled out of that construction hall you see on the right. Work is finished and she is ready to be moved into water, or the opposite, she is on her way into hall.
Why do you expect noise from this door? When shut the casing is smooth and nothing sticking out. Looks to be for supply delivering , a lot of boxes on the casing. It is not for loading of torpedoes, all torpedoes are loaded in front of boat. Look at this picture from subsim.com :

Interesting and brought back memories when you mentioned the Hovering systems on the Sturgeon and boomer class boats. I did alot of hydraulic work on those boats. Also about the LA's in this regard. I did not catch it the first few on which I worked ...but then somewhere it became noticable by the differerence in them.
When a boat is moved into or out of a position...there are certain connections/ support facilities which accompany her. Especially a boat with a reactor which has gone critical verses one which has not. Cooling water is one of them. A sanitary connection for pumping off waste unless you intend to pump it overboard onto the concrete pad on which this boat is sitting........
The doors on the the pictures are not the same, thats why I mentioned door for delievering supplies. The two doors for torpedo delievery are further to the front of the subs. Btw, the quality of the picture is not good enough to conclude if proper hinges etc are fitted.
Indeed...good question. It is called flow noise. If one ever stands on a pier with handrails on the side..in high winds the handrails will sing...they will hum to a resonant noise. Flow noise will do the same thing at certain speeds.
The picture you are linking shows two doors in the torpedo loading system. The door in your link seems to be the door which is further aft...the forward door being closed in the photo to which I referred. What I know from experience is that fastener...locking systems.. tend over time to wear out, meaning loosen..causing slack in the doors. This is a double hull boat.
Look at the photo you linked...the front door..has a taper towards the bow. This taper does not appear to be heavily supported....by hinges or such. This is where one can get flow noise at certain speeds though at the other door it is possible as well.
Dont they all?? Unless proper maintenance is beeing done...
While I don't have the article on hand to link...one of the articles I found while researching the name you provided Gephardt..mentioned this in that the Russian boats tend to be more noisy as they age.
Of course there is some receiving cradle inside. What makes you think there is not? Do you think they are received by hand and stored on the racks?
This torpedo is being supported in a lifting rig attached to the center of gravity on the weapon. What is supporting this torpedo once it is lowered into the outer hull. There must be some kind of receiving cradle there. You don't want to be bouncing, jarring or knocking a torpedo around. The fuel type often used........
What are you talking about? The torpedo-doors? Remember russian subs have tubes in the bow..what you see is torpedo-doors. They do not load torpedoes there. Well, on Kilo class they do actually. They lower a delivery cradle down to water-level and slide the torpedoes through the tubes.
There are also traces of such a door outlines at the waterline across the bow..from port to starboard
