[TEC] Sub data ?

[Redwine]

Please, if somebody have info about the basic submarine data, share it here.

I found this... is it corresponding with your data ?

Please add your data, or lossed data...

plus what was the relationship between the test depth and crush depth for USA sub... wich security coheficient they used...?

Submerged endurance was 48 hours at 2 knots (96nm at 2knots)

Test depth: 250ft (76m)



Sargo Class :

Speed: 21 knots (surfaced), 8.75 knots (submerged)

Range: 11,000 miles ( ??? Knots)

Test Depth: 250 feet (75 m)



Tambor Class :

Range: 12,000 nautical miles at 10 knots (18,000 km at 19 km/h) surfaced

Submerged endurance was 48 hours at 2 knots (96nm at 2knots)

Test depth : 250 ft



Porpoise Class :

Speed Surfaced 19 knots (35 km/h), submerged 8 knots (15 km/h)

Range Surfaced : 12,000 miles (miles or nautical miles ??? ) at Speed ???

Range Submerged : ???? at speed ????

Test depth: 250 ft (75 m)



S-18 Class :

Speed, Surfaced 14.5 knots

Speed Submerged 11 knots

Range surfaced ??? at speed ???

Range submerged ??? at Speed ??? (120 battery cells)

Depth Limit 200' (60m)

Tambor Class :

Speed: 20 knots (37 km/h) surfaced; 9 knots (17 km/h) submerged

Range: 12,000 nautical miles at 10 knots (18,000 km at 19 km/h) surfaced

Submerged endurance was 48 hours at 2 knots (96nm at 2knots)

Test depth/depth limit ????


The Test depth for the Tambor would be 250ft (75m) All data can be found at this site: http://www.valoratsea.com/boats.htm

Many thanks !!! :up::up:

Sorrry DeePsix501, but i cant found the S-18/S-19 Class there in that link ...

There are other S-Class there ,,, S-1, S-11, S-42, and S-48..... but not the S-18 and S-19...

Had the S-18 class same values than S-1 and S-11 ?

As far as the sim and zon files go, the S-18 and S42 classes are the same. The cfg file for the S42 looks at the S18 files.

I am not sure how Ubi decided on making the S18 a class - it is reminds me of how they lumped the Type IIA and Type IIB all together, all the Type IIB hullnumbers were assigned as IIA's in game.

Some of the data on the Valor at Sea website differ significantly from Friedman's 'US Submarines Through 1945'. I'm not sure which to belive, though the depth of information contained in Friedman would lead me to belive it rather than a website.

Data for the S-18 from Friedman:

Length: 219' 3"
Beam: 20' 8"
Draught: 17' 3"
Displacement: 930 tons surfaced, 1094 tons submerged
Complement: 4+39 (peacetime)
Power Plant: 2 x 600 bhp surface, 2 x 1,175 hp
Battery Capacity: 9,500 Ah (drain rate not specified)
Speed: 13 kt surfaced, 9 kt submerged
Endurance: 3,420nm @ 6.5 kt surfaced, 20 hours @ 5 kt (equates to 100 nm)
Test Depth: 200'
Armament: 4 x 21" bow torpedo tubes, 12 torpedoes; 1 4" deck gun

Interestingly, although I (along with others) complained about the subs not having enough range, tests I've done show that the range in SH4 is *massively* greater than the realistic ranges. For example, the S-18 in-game will travel 31,700 km (17,100 nm) at 5 or 6 kt if the navigator reports are to be believed. The data I've collected in-game agrees with all the values I've found in the .sim files for the submarines.

Ranges listed in Friedman's book and in ofifical documents take into account something like 25% fuel reserve for charging the batteries.

Still, allowing 25% fuel for battery charging the range is 4,560 nm...quite different to 17,100 nm! Have I done something wrong or is the range a game-balancing thing?

There is an even higher range listed in Friedman which is available with fuel stored in the main ballast tanks (I think it's about 8,000 nm on S-18, not including the 25% for battery charging) but even this is still nowhere near the SH4 figure.

[elanaiba]

Well, I admit that the range was increased a little from the standard. The game requires too much long travel/high timecompression even when going faster than the nominal 10 knots.

BTW the in game specified range for the S-18 is 8000 nm/9.5 knots which is somewhere between the 1.25 x listed value and the 8950 nm of the "fuel in ballast tanks".

[Prof]

The test I did was to start from all stop in calm sea conditions then increase the speed in 1 kt increments, wait for the speed to stabilise, then ask the navigator what was the range at the current speed. I did get 8000 nm between 9 and 10 kt (as set in the .sim file) but the maximum range was actually between 5 and 6 kt. I'm planning to repeat the tests with all boats and post the plots at some point...hopefully tonight :)

BTW...thanks for the excellent work, elanaiba...too many people are complaining about what's wrong than praising what's right :up:

Many thanks boys for all job and data, do not forget to post any data you discover... :up:
