I grabbed the IXB Donitz was offering for my first patrol. As I motored out of port and hit the bay, I decided to submerge and see how fast this tub will do it. I never screwed with the IXB. Anyway, I submerged and jumped on the hydrophones. I hear something at 10 degrees starboard. It was faint as my electric motors were going. I asked for full stop to listen. I keep hearing electric motor noises. I look at the helm and it shows motors stopped. But I keep hearing electric motors just like mine

OMFG there is a submerged sub around me.

Friend or Foe?
You GWX boys just keep on surprising me!!!!! As I'm typing this I still don't believe what I was hearing. Unbelievable! You guys
