Thanks Trevally!
The uboatsensors.sim file from NewUis is newer, but as mentioned earlier, if I put the no hydro mod from IRAI first, then it's still as if I have sonar while surfaced. Right now, I have no hydro after NewUis in order to get it working, so I'm not sure what's missing between those files.
Another thing I wanted to note was that I bumped into a convoy that had a good five troop transports in it. When I identified them, they came up as "AOTDMadMax/Stormfly/SteelViking Big Modern Passengership". At first, I thought it was a mistake, then I thought it might be an easter egg, so I did a search and found a reference to the Imported Ship Pack. It looks like that is what they intended. For me, with all due respect, that naming convention was an immersion killer. Those ships did help me get the tonnage I needed, though.
