The episodes each told a short version of a real story. Each episode was introduced by a real admiral, and after each episode one or more of the crew members involved was interviewed. In the episode featuring
Archerfish and the sinking of
Shinano, Joe Enright was played by DeForrest Kelly, later 'Bones' on
Star Trek.

I was able to watch a few of them online, but I don't remember where now.
