[QUOTE]Originally posted by shark
[B]my US S class subs get occasional torp hits but suffer heavily from jap asw ships.
jap I boats have repeatidly penetrated my cv screens,obtained multiple hits on CVs and got away undamaged!
The CV screen had 6-8 of my best DDs,and CVs were operating undamaged.this has happened in 1.2 ,1.1,and 1.0.
Also the later "named" subs never seem to hit, I know the new torps are suspect but Morrison mentions a succesful strike by Nautilus at Midway on a heavily protected CV,followed by a succesful evasion.
Are there any plans to improve US ASW and sub performance further, or reduce Jap Performance ?
Thanks for giving pac war a worthy sibling. [/B][/QUOTE]
According to US Submarines Through 1945, Norman Friedman, Naval Institute Press, 1995, 379 pages:
on Page 137:
The S-boats all lacked suffiecient range for Pacific operations, and postwar exercises often overtaxed them. To achieve rated endurance, they had to stow fuel oil in their ballast tanks. They left oil slicks every time they submerged until the tanks were washed clean."
United States Submarine Operations in World War II, Theodore Roscoe, United States Naval Institute, 1949, 577 pages sums up US submarine torpedo performance as follows (the S boats had mk10, the fleet boats MK 14):
pg 263.
US submarines sank many major Japanese men-of-war-ships in the carrier and cruiser categories, and one specimen in the battleship class. Yet, of the total sunk, less than 15%-just three major warships, to be specific-were sent to the bottom before the exploder faults were corrected. Even so, the three warships dealt the barest minimum of credit to the faulty Mark 6 exploder. For S-44 sank the heavy cruiser Kako with Mark 10 exploders which were fitted with the simple contact exploder. Nautilus sank Soryu after the Japanese aircraft carrier had been lamed by American aircraft, her hull plates bomb-weakened. And the third of these vessels, Tenryu, sunk by Albacore, although classified as a light cruiser, was an old-timer, little larger than a modern destroyer.
Compare these first three sinkings with the successes scored later. In the last half of the war the US submarines using the corrected exploder sank over six times the number of major warships downed by torpedo attack in the first half. Japanese merchant men also went to the bottom with greater speed and consistency. There was no Tonan Maru No. 3 exhibition during the last 18 months of the Pacific conflict.
The torpedo trouble was well cured by the end of 1943. It had been a tragically expensive muddle. The cost to the United States ware effort in lives, dollars and time remains incalculable.

My comment: The latest changes make it about right. I don't see any need to adjust it.
