(now easy to do-yourself with the Mini Tweaker, but I'll save the effort to those who don't feel like it)

Adjusted underwater endurance for all fleet submarines. Based on the following research
data from the Fleet Submarine Manual.

Maximum Time Submerged and Cruising Range vs. Submerged Speed Knots
knots--miles(peace-time)-- miles (war-time) --hours(peace-time) -hours(war-time)
2 ------73 --------------100-110 ------------36 ----------------55
3 ------69 --------------100-105 ------------24 ----------------38
4 ------55 --------------83 -----------------14 -----------------24
5 ------40 --------------64 ------------------8.5 ---------------14.5
6 ------30 --------------48 ------------------5 -----------------9
7 ------20 --------------31 -----------------2.6 ----------------4.8
8 ------14 --------------23 -----------------1.6 ----------------2.6
9 ------9 ---------------15 ------------------1 -----------------1.5
10 -----10 --------------X--------------------X-----------------X

Mod uses the 4-knot wartime endurance as base; original SHIV used
2-knot endurance as base which did not function properly and
power usually ran out in only 5-6 hours at 4 knots.

Your boat will now be capable of making the above figures fairly accurately.

The older, smaller Porpoise class has 25% less battery charge than
other fleet boats.

Good job! You beat me to it. But be careful when using the word 'realistic' in your mod titles. Some people might not like that. :rotfl:

[CCIP]

Yep, tell me about it :p

But hey, in this case it's both numerically accurate and has the right result. Not sure what to complain about there!

There is, however, the issue that the battery recharge time seems to be shorter than it should be (not affected by this mod), but I really don't have any idea how to adjust it. I don't think it's even in the .sim files. (On the other hand, we had the discussion regarding battery recharges with NYGM team long ago, and it's a really complicated subject matter to model in a game, so we never came up with a final answer)

Sweet, saved me the trouble. One less thing i have to work on tonight, thanks man

[tedhealy]

Excellent

indeed, except this is substaniated by an actual source (and not just "i feel")... a good example to follow.

nice work CCIP!



edit: 'shame though about the s-class...
'been scouring around for similar data for it but no joy.
i'm guessing that it's values would be similar to that of the porpoise, unless anyone has further info?

[pcelt]

In order to install this mod data is it crucial that we have selected

IMPERIAL UINITS and not METRIC in the Options

Thanks--very inexperienced with modding and tend to attract tech disasters.

[Zero Niner]

Thank you.

[Krupp]

Excellent! Thank You!

[pcelt]

With apologies may I reask what is probably a very unnecessary question---
----Will this specific mod operate equally effectively and with the same results whether you are using in-game Imperial (miles )or metric (kilometers) as your distance measures.

Please just clarify this ---many thanks

[CCIP]

Should not be a problem, there is only one value in the submarine .sim file, and it was always in miles (even in SHIII which was metric-only).

You can test it easily - if a gato sub can stay underwater for about 24 hours at 4 knots, then it's fine. In stock game it would run out of power in about 5-6 hours.

hi CCIP good work just D/Led you crush depth's and battary's mod's and notesed that you isnt entry for the two S-bouts. and there isnt an entry for the new S-41's that where in the patch.

sorry if i just p!ssed on your effats but just thort you should k now

[CCIP]

S-42 is actually just a slight visual modification of the S-18 and shares all the same performance data (just like the Gar shares all performance data with the Tambor).

As for S-boats in general - as I mentioned in the request thread for this, I haven't been able to find any accurate data on the S-boats' submerged performance that is any different from what we get in game, so I left it alone for now. I get the sense that the S-boats are overmodeled (unlike the rest of the boats), but I can't prove it right now...

[Banquet]

I found this link;

http://www.navy.mil/navydata/cno/n87.../forgotten.htm

which gives these stats for S class;

Length:
225 feet Beam:
21 feet Draft: 17 feet
Displacement: 960 tons surfaced
1,130 tons submerged Surface Speed: 12-14 knots Submerged Speed:
10 knots Surface Endurance:
3,500 nm at 6.5 knots
Submerged Endurance: 20 hours at 5 knots
Complement: 4 officers; 39 enlisted men
