All what you need.

Thanks. A lot of useful stuff there.
I have two questions though. Can you tell us what was your source for all this data? And, since you seem to have more knowledge of Soviet torpedoes than anyone else in this thread perhaps you now whatt type of warhead are used in Soviet torpedoes in the game (UMGT-1, Test-71, USET-80, SET-65, in case you don't have the game)?

There is a slight problem with using this data in a game though. As far as I know, acquisition range for torpedoes is constant, meaning, if you set torpedo range to 4000 yards it will always detect anything within that 4kyds regardless of any coating. And not every Soviet sub in the game has them (looking at the files, Novembers and Alfas don't).
But, since most of them have, I'll leave Mk48 range at 1600 yards.
As for other torpedoes, looking at this data shows that (feel free to correct me if I'm wrong):

Test-71 - should have detection range of 2600 yds (your site says it's 800m, but was released from 1976 so it was tested against coated subs, so 800m*3 converted to yards is around 2600

SET-65 - theoretically it should have the same range as Test-71, but since the set-65 is used by the '68 era subs I've decided to use earlier models, which means 400-600m for surface vessels. For a torpedo in the game I think 400 yds is a good number.

USET-80 and UMGT-1 - your site tells us it's 1500m. If we assume it's against coated subs, so the range against uncoated US vessels in the game should be 4500m = 4900 yds. A bit much, but that's considering the ration of detecting coated/uncoated sub is 3:1 (is there any example of a torpedo being tested against both for reference?
