Snorkel.

Welcome Ivan :sunny:

Thanks again! Also shouldn't the Alfa have an operating depth of 800 meters and a crush depth beyond 1300 meters?

Where did you get those numbers? The only sub that I remember that could operate at 1000m was Mike class.

I have multiple books that say the operating depth is 800 meters, also on Wikipedia as a claimed depth. If you wish I can gather the sources if you wish confirmation and not just have word of mouth :salute:

Also are you a developer for this mod? If so thanks for making the game so much more interesting!

That data would be most welcome, as would be the books themselves.

No, I am not.

Here is my first source which explains the Alfa's supposed crush depth http://web.archive.org/web/200602051.../ship/deep.htm

I will get the other sources later today.

Cold war era (1984) western source, that explains it.

Note that a dedicated FAS article here:
http://fas.org/man/dod-101/sys/ship/row/rus/705.htm
Has conservative numbers.

Here is the book "Submarine" published by DK books (yes it for children) where it mentions its depth as 900 meters

I wonder what Jane's Fighting ships says.

I don't see how it is referenced or where they got those figures from, so difficult to comment.

However for some reason the figures in all Russian sources tend to be lower.

Yes that does seem to be the case, but could it the information is presented that way to hide its capabilities? The US navy does the same thing with information about its boats, so why wouldn't Russia also do it?

And a fun story for the Skipjack class is that is stated with a top speed of 29-36 knots but when Skipjack first shipped out with a five bladed prop they could actually push 54-55 knots (but it was loud as sin so everything could hear it) so they replaced the prop and had to go a lot slower (this is from an old trusted friend who served on Skipjack BTW).

Alfa class is no longer in service, nor do those figures make logical sense, as then there was no point in the development of the exceptional Mike class. In reality the titanium hull was there not to allow those subs to dive deeper, it was to make the hull lighter and thus keep the displacement down (the original requirement was for 1500 tons I think).

I trust documented sources. Which say that record for the under water transit is held by Papa class going much slower.

I understand your desire for trusted sources (in relation to the Skipjack) and that the lack of material/information regarding this information however it was only on the first time she shipped to sea and less than 95 people where there. Not to mention it was once classified information. But in terms of the Alfa's current diving depth it just seems shallow compared to multiple sources. On the issue of secrecy and why it would matter, the Top speed and diving depth of USS Albacore is top secret and that was diesel electric test sub from the early 50's! Military information can be purposely wrong/classified no matter how illogical it is to keep it that way. Of course I don't decide what information/sources you use but I like to look over everything I find. :D

We can go into conspiracy theories or study physics, which tell us that top speed for the vessel (per same shape/displacement) depends non linearly on the power output of the power plant.

And there is a world of difference between 55 knots and 35 knots power out wise.

I'll ask the old salt again it might have been a lot slower

Also I have found a bug where taking the Rubis, Suffern, or Amethyste out on a quick mission or selecting their load out crashes the game and they are completely unplayable.
