I finally adjusted nuclear subs PSL levels in LWAMI 3.10 according to my best knowledge and data:

- US: LA 62, Ohio 57, LA Imp 58, Seawolf 55, Virginia 55

- UK: Switfsure 63, Trafalgar 59, Astute 56

- Russia: Victor III 67, Typhoon 65, Victor III Imp 63, Mike 64, Akula I 62, Delta IV 62, Oscar II 62, Akula I Imp 59, Akula II 58, Graney 57, Borey 59

- China: Type 093 Shang 66

Now I think they are quite correct.

Hmm, where exactly do you get those numbers man? Don't you think the modders (LWAMI or DWX) do their research? I really have no idea what you are basing your PSLs on, other than wikipedia and pure speculation.

I don't know where they did their research but I do not base my estimates on what Russkie old-farts from Makakhit and Rubin Design Bureaus twaddled about rusted Graney and Borey subs being equal or even more quiet than Seawolf. In fact I would be more trustful to specialists from Toshiba on that issue.

Anyway here you are an indirect answer: Seawolf's PSL=55, Graney's PSL=55 (taken from LWAMI 3.10 platform reference guide).

Reality is another story: US simply achieved another qualitative breakthrough in submarine's noise reduction over Los Angeles class SSNs having developed Seawolf program 15-20 years ago. The widely known fact is that in those days US were ten years ahead of the best Russkies had thanks to Seawolf's technology which means they regained lead in submarine warfare again as in the 1970s. As one can note at that time Russkies had on hand: Akula I Imp/Akula II SSNs introduced into service and Graney/Borey programs already launched. Of course in the last 20 years Russian naval R&D base effectively collapsed so only very naive people can think Russkies were able to catch-up Seawolf's technology level. In the meantime US developed next SSN project called NSSN which materialized as Virginia-class. What is known Virgina SSN is at least as quiet as Seawolf being in some ways more advanced design - so US were still making progress in this area. On the other hand Russkies after 15 years of silence showed their "brand-new" submarines which are essentially examples of late 1980s to early 1990s technology. In sum Russia is now 10-30 years behind the US and that is all story.

Translating all that into DW/LWAMI universe: If we assume Seawolf's PSL=55 as a baseline so generational step ahead over 688I's PSL = 58 is 3 points. Yet Russian Akula Imp and Akula II are believed to be more on less on par with 688I noise level and that is why I granted them with PSL equals to 59 and 58 respectively. Later I assumed that Graney SSN is founded on improved Akula II technology being slightly quieter but not generation ahead as new American nuclear subs due to all above obvious facts from reality. Thus Graney's PSL value should equal 57 being "two PSL points louder" than Seawolf's PSL or 2/3 generation behind it. Similar considerations leads to conclusion that Borey-class SSBN should have PSL about 58-60 being still more noisy than 30 years old Ohio-class SSBN (maybe after some stealth upgrades) but better than late 1980s Delta IV SSBN.

As you already mentioned, the data is the platform reference chart is off, we have the Graney at 56. So you're making a huge fuss over a 1-point difference from our estimation to yours. Got a lot of time on your hands?

After reading through the treads regarding the mods available, I am still at a loss what they will do. How they differ from on and the other? What will they change? How will they change the gameplay and a decent install instructions!!!

Preferably that should be stated in the first post of the thread, not on page 3 og 6 or a link to another thread!

Thanks for the modding efforts.

I've finally installed your mod and it's awesome!
There are several posts about the mod, so I will try to put each thing on its place.

I have a CTD in the USNI reference when selecting the Swiftsure.

Also in the USNI reference, Chile appears as CHLIE.

Messing up a bit with the DWedit I saw that the Shang class has the same propulsion as the Han... I have no references or bibliography to back this but, shouldn't it be quieter than the Han? I see that it's passive signature is lower (so reactor noise improvements, I suppose), but really they have not improved the propulsion?

One last thing: cycling on the 3D view of the DWedit I had various "bitmap missing" on some platforms. I don't remember which ones, but is not hard to discover. Later I will post them.

Thank you for the mod!

Noted... who would think stupid text files would cause so many headaches...

Whoopse! At least I didn't spell it chili...

The thrust? I think we use the same thrust for all the low end SSNs. All it really does is make them noiser at higher speeds than higher quality ships.

If it was the Al Jouf I think we fixed that in the next release or something. But if you can list them it would be very helpful since I use my computer for testing and such I may have bmp files installed already that were left out of the release or not in the installing .bat for some reason.
