basically, there’s little to add to Blackcat’s explanation. It’s a simple and good explanation he did.
On merchant ships, we use Heavy Fuel Oil. This oil requires a temperature of about 30°C minimum to be stored, then it goes to a other tank and is heated to 40°C (because otherwise the stuff is not really liquid and can’t be used for propulsion), from that tank, it is pumped to the engine. For keeping this oil at this temperature we use a boiler. That boiler uses water, heated by the exhaust of the engine. Therefor we keep the engine running all the time, even in port. ( we also do that because otherwise the engine cools down and when it comes somewhere near 30°C, it would start leaking etc, because the parts would shrink and the engine would be totally wasted, hence the engine is kept at about 75°C.)
We also use diesel fuel, but that is only used in port, because it allows for a quicker increase and decrease in RPM. It’s for manoeuvering. (basically, a large ship carries about 2,800ts of HFO (Heavy Fuel Oil) and 700ts of Diesel.
HFO is very cheap, hence for merchants.
Diesel on the other hand is very expensive, but for warships, who do manoeuvers all the time, it is used more.
Gas Turbines are usefull, but use a lot of fuel…
A turbine is based on the principle of “labour” done by a gas or steam. This labour, depends on the change of volume and the pressure. dW=p x dV. So, when the volume (V) increases, the labour (W) will increase. A turbine is cone shaped, the gas/steam is blown in the narrow part and goes to the larger diameter part, hence expands, volume increase, increase of labour. This labour is used, because the “cone” is filled with many rows of “propellor” blades. The gas will make these blades turn, they are connected to a gearbox and then to the shaft.
They allow for great performance, but as said are expensive, complicated and use a lot of fuel. For warships this is ok, but for merchants it isn’t…

To generate the gas or steam, the boiler is used.
This is a drawing of a boiler, which I made to explain (well at least tried to) the principle of free circulation for a nuclear plant to someone. This is the operation of a boiler, as you can see, it’s a free circulation of the water.
The pipe on top, where the water vapor goes out, goes to a superheater, which will add some more heat to the vapor. Then it is fed where you need it, be it your pipes to keep the HFO hot in your double bottom, or your steam turbine.

of course I don’t remember it since I never saw it. I don’t come out of the Navy sections. I do have a model 1/144 of the cruisemissile… (sublaunched version). And I ‘m indeed no airman, when you hit a plane with a missile, 99% will go down. If you hit a ship with a missile… It’ll stay afloat and at least give part of the crew chance to escape. Plane’s are for sissies, if they run out of fuel, they go down, for a ship, that’s a different story. 😉 OK, now I’ll stay quiet and look for all the flaming that’s going to come from the AF guys 😀

Russia doesn’t need such weapons at the moment. If they indeed succeed quite cheaply in adapting any of the new cruise missiles you mention for Submarine use, then they should do it. But otherwise, if they really have to invest too much money, I don’t think it’s worth the effort. I’d first like to see these submarines sailing instead of arming them with cruisemissiles to lay in port.
Is the AF indeed getting those new missiles now? It’s been mentioned for some years now, but haven’t seen any of that…

Doesn’t look nice does it? They practically disabled the ship. The guidance radar (for SeaWolf) seems to be completely wasted, so is the SeaWolf launcher… They should be lucky that nothing really blew up!

Yes, brass is a very good condutor, hence it will return radarwaves better than certain other materials. I think it was the purpose to have a slightly overrated result and maybe it was more clear where the bad constructed (the RCS increasing- parts were by using Brass… Don’t know, hence I’ll have a better look at that book and the explanation again. I only read the comment with the picture, maybe there’s more info in the text itself.

I have a whole bunch of them. I don’t have any on a single forum, only on all the different forums I pay a visit to. That’s about 6 or more of them. Some I’m not active anymore though.

Now we know why there was no slipway in the area, look at the fences around the conning tower and the bar along the lower hull where the fences support on

The torpedo tube layout, which also fits. Of course, who would put a sub like that? The FRENCHIES, I could have known that :p .

That’s why it looked so small, it’s only the forward part of the sub… You can count the supports on the hull… And of course in the other picture you see it’s built in two parts.
So, I’m sorry guys, this is NOT Yuan.
