Raverdave - I'm still at work, but here's some prelim info on subs: The modern US subs (Gatos, etc.) had a combat patrol time of about 45 days. This includes transit time, so more like 30 days in the combat zone for most patrols. That number should be higher in UV because the distances aren't so great. The S class and older subs have a patrol time of about 30 days, more like 20 with transit... They're old, leaky, slow, and can't dive very deep - not too effective, although the S-39 did put the Kako (Jap CA) down off Kavieng following the Savo Island debacle. The funny thing is the S's used the mk. 10 torp which, although older, was not plagued by the same probs as the new-fangled Mk. 14s. If the S could get in position, it often had a better shot of putting a ship down... Japanese subs were not as standardized - many more flavors, from giant float plane carrying subs like the I-25, which had a 14,000 mile radius and logged at least one mission I know of that lasted around 2 months. The other end of the spectrum (ignoring midgets) is the RO types. These were coastal subs, similar in size to the S class - mostly more modern though. They had ranges about the same as well - 20-30 days at sea. I'll get more specific data when I get home, but this should help for now. Also, I came across an interesting site today which is still being completed. It doesn't have a lot of info, but some of the tidbits are interesting, if only in an anecdotal way. http://home.st.net.au/~dunn/japsubs/japsubs.htm
