Submarines, finally ...

Soviet submarines in different modes and many options for sea mines.
Thanks to McGuba and Guille for their support.
The combat actions of the submarine did not go beyond the Black and Baltic Seas and the North.
The ocean capabilities of submarines were not applicable here.
So in the beginning I decided to make two modes for the submarines.
Mode #1. Surface.
Cruising mode.
Class - capital ship
Spot = 1.
Speed - high
AD - low.
There is an attack of ground units.
Mode #2. Periscope depth.
Patrol, attack.
Class - submarine.
Spot = 3 (since submarine in patrol mode).
Speed - low.
AD - med.
+ Camo trait.
But I still think to add another mode of the so-called "Lie down on the bottom".
Quite often during the Second World War, Soviet submarines fell to the bottom for several days,
and if it turned out they went to the base.
But it still requires testing and other things.
We are very limited in the mechanics of PZC.
But I'm thinking to emulate a limited stay under water.
Having made that in this mode 30% of fuel per turn were lost.
Then for example boats of C-class, Shch -class can be in this mode of 3 turns and M-class only 2 turns.
After that, they may not have enough fuel to return to the base.
Therefore, i also need to think about add another mode - "Towing."
When a unit without fuel will be given a small number of points of movement, so he got to the base
I did not quite understand how the submarine detection mode works in PZC.
I was faced with the fact that the class of submarines is detected using spotting, even at long distances.
And probably after detection, the submarine will always be visible.
If you know how the submarine detection mode works, write.
Due to the fact that the submarines in the class submarine are often detected, I decided to add the Сamo trait.
Also I think it's essential to change the spotting system for all ships.
The principle will be that the capital ships BB, CA and destroyers - spotting will be reduced.
And for small ships such as boats, patrol ships are increased.
And I hope that the battles at sea will be more about finding the enemy than shooting at the enemy from afar.
OK. We return to our submarine which after the battle campaign got home.
By self move or after towing. And it has some damage.
What's next?
In this mod capital ships will not have the possibility of repair. It is necessary to operate capital ships carefully.
But the submarines will have several options.
They will have to be repaired during the scenario but it will be quite expensive.
Also I will try to make such a mechanic - when they can be repaired +1 per turn, through triggers
in a number of special ports in which there will be shipyards (not in all ports).
Then the repair will take some time. And the unit will be repaired only in the Surface mode which will make it a good target for enemy aviation
And of course there will be a repair between the scenario.
Initially a double independent prestige system was planned.
During the scenario prestige is spent on replacements and upgrades.
And between the scenarios prestige is spent on reforming and upgrading.
Moreover, the prestige between the missions will not be available after the start of the next scenario. Possibilities to accumulate prestige and then to spend at once will not be.

Therefore for an expensive repair for example a submarine between scenarios prestige is enough but during the scenario may not be enough.
I have such thoughts and ideas for today.
