READ THIS DESCRIPTION
A briefing on the development of anti-aircraft weapon systems for U-boats.
I'm not sponsored by the http://www.usni.org but I am a member and encourage you to consider getting a membership too so they can continue their mission of being the preeminent source of military naval information in the world. USNI makes it possible for anyone to research and appreciate naval history and we should all support that.
ERRATA
I misidentified the U-boat on the opening slide and slide 25. That is not a Type IX, it is a Type VIIC, specifically the U-763. I was able to ID it after noticing the emblem on the side of the conning tower.
