I tried installing UBE and made a single patrol and had significant issues. I ended up boarding a freighter and while investigating them, a group of 4 destroyers showed up. I found the freighter was heading to a blockaded port, ordered evacuation, returned to my ship and dove. The DD's knew where I was (likely called by the freighter) so I slinked away to about 4500 m and launched a stern torp at the freighter that would have resulted in an impact angle of about 70 degrees. Torpedo was a dud. Reloaded, warmed, launched again. Dud again. All in, I launched all of my torpedoes at this ship... All 14. All duds. All at a depth of either 4.5 or 5.0 m (I can't remember which I used but that's where my torps are set for freighters with DD's around). Impact angles would have been between 70 and 80 degrees for all and I thought maybe they were "cooling off" while in the water so came in to as close as 1400 m for the last 4. All duds....

So I had to return to port to restock. I started heading in and ran into my second issue. When I was a safe distance from the freighter, I surfaced to get some distance faster. There was a plane on top of me. Dove again without having a chance to recharge my accumulators. I continued on for about 2 hours submerged and tried again. Again, plane on top of me. Dove again (still very little recharge on the accumulators). I continued submerged until my batteries were running dry and surfaced again. Again, there was a plane right on top of me. I didn't have enough left in my accumulators to dive and resurface, so I had to try and fight it off. I ended up getting sunk.

So....two questions. Is that dud rate intended? Was I somehow set up wrong?? I can understand needing to be CLOSE to 90 degree impact angles, but +/- 15 degrees seems like a pretty narrow window. Second, what is with planes following you while submerged. I was at a depth of 50 m, so they weren't seeing a scope or something. This seems a bit much for 1940. The only thing I can think of here is this was on the mission where you pick up a guy from a ship in Spain or Portugal and then receive a note that the RN is waiting for you along your "expected return path". Any chance they're just flat out hunting you in a scripted event??
