[REL] Playable Russian Subs

[Daldryk]

I changed the Alfa Class, based on the real one.

Engine: 1 liquid metal reactor operating 2 steam turbines, driving 1 propeller with 5 blades.
Speed: 20 knots on the surface, 45 knots in diving.
Immersion: operational, 600 m; Maximum, 1000 m.

Where did you get that data?

[cookiemonste]

From my sources, the Alfa's could go 41 knots and could excellerate for a short sprint to 45 knots.

Web sites and videos russian on Youtube on this submarine. After comparing its speed varies from 41 to 45 noeuds, then be aware that there are two classes of Alfa I and II.
I've been testing the maneuverability and power with Cold Waters. At this speed in depth it corresponds well to what is said of him. Capable of avoiding a torpedo very grabde speed. A submarine that turns very quickly. Of course he does not avoid all the torpedoes, but that is his advantage.

I would take the russian videos with a grain fo salt. The russians are known to inflate some data to make stuff look better.

Can you, please, be more specific?

Where did you find out the difference between pr.705 and pr.705K (and I generously assume that you use Alfa-I and Alfa-II designations to destinguish between the two) in terms of speed?

As far as I am aware:
- you got the dive depths (рабочая and предельная)
- you got the speeds wrong (though you did correct yourself later, in reality the 41knot speed was not usable outside of trials and the subs never exceeded 39 knots)
- you got the number of turbines wrong (as far as I am aware both pr.705 and pr.705K use the same turbine - ГТЗА ОК-7)

If I recall correctly, those figures were heavily inflated by spooked NATO intelligence agencies.

The only sub related videos that I have watched so far are either in eng (ie subsim playthroughs) or are accurate. The figures availiable on the commonly used russian web sources conflict with the ones he has supplied.

My guess would be that he is using outdated cold war era data, especially on things like dive depth, because back then the assumption was that titanium was used to improve dive depth, not to make hull lighter.

[cookiemonste]

Even the russian wikipedia quotes a topspeed of 41 and a test depth of 450 m. 600 m could be a opperational depth, but it would still be very deep.
@ikalugin: look at this:

Yea, the only titanium deep diving combat sub that we have built was Mike, which had 1000m operational depth.

[Daldryk]

In two words no one really knows, unless you've tried it... I add that we are in a kind of simulator everything is allowed in mod. The settings suited me.

[CaptainX3]

That's the fun of modding, you can tweak and change whatever you'd like. I don't intend to change any stats in my mod unless someone points me to a credible source, such as Wikipedia or something similar.

Some things in the mod I've had to make educated guesses on (Like the Typhoon VLS conversion), but I try to keep things at least semi-realistic.

[DarkShark22]

Hi!
I really like your mod and I have used every soviet sub!

I just couldn't help noticing that the Yankee class and the two Delta's don't have VLS while SSBN's should be able to launch missiles, right? (just like the Typhoon in-game). Are you planning to give them VLS?

(my english isn't the best, I'm Dutch)

[MadMike]

Reliable Russian source online says the Project 705 (Alfa) class sub had a surface speed of 12 knots, submerged 40.2 knots.

Operational diving depth of 320m (1049 feet), max of 400m (1312 feet). Only seven operational, assigned to the Northern Fleet.

Yours, &c.

Mike

[cookiemonste]

That sounds about right.
I should learn russian.
