Since there is some interest in this, I edited the values showing the real-life figures from SUBMARINES THROUGH 1945, by N. Friedman:

United States S-18 class submarine (1939 values)
13 knots surfaced
9 knots submerged
20 hr. @ 5 kt.
200 ft test depth
4 forward torpedo tubes
12 torpedos
3420 nm @ 6.5 kt. endurance

United States Porpoise class submarine (1935)
19 knots surfaced
8 knots submerged
10 hr. @ 5 kt., 36 hr. at min. speed
250 ft test depth
4 forward torpedo tubes
2 aft torpedo tubes
16 torpedos
6,000 miles @ 10 kt.

Salmon class submarine (1937)
21 knots surfaced
9 knots submerged
48 hr. @ 2 kt.
250 ft test depth
4 forward
4 aft
24 torpedos
11,000 miles @ 10 kt. range

Sargo class submarine (1939)
21 knots surfaced
8.75 knots submerged
48 hr. @ 2 kt.
250 ft test depth
4 forward
4 aft
24 torpedos
11,000 miles @ 10 kt. range

Tambor class submarine (1940)
20.4 knots surfaced
8.75 knots submerged
48 hour @ 2 kt. endurance submerged
250 ft test depth
6 forward torpedo tubes
4 aft torpedo tubes
24 torpedos
11,000 miles @ 10 kt. range

Gato class submarine (1941)
21 knots surfaced
9 knots submerged
48 hour @ 2 kt. endurance submerged
300 ft test depth
6 forward torpedo tubes
4 aft torpedo tubes
24 torpedos
11,000 miles @ 10 kt. range

Balao class submarine (1943)
20.25 knots surfaced
8.75 knots submerged
48 hour @ 2 kt. endurance submerged
400 ft test depth, 600 ft emergency
6 forward torpedo tubes
4 aft torpedo tubes
24 torpedos
11,000 miles @ 10 kt. range

The figures for surface range (endurance) are based on "normal tankage". He gives figures for using ballast tanks for fuel as well, but they seem dubious to me, so I just gave the normal figures.


You may have noticed that you do not get nearly the submerged endurance that you should, in the game. Much has been written about this. Suffice it to say, the game model is broken - badly!
