4/5 A Good Introduction Into the Modern Silent Service
  by M. A. Ramos (Florida USA)
This short documentary of just under an hour gives you a very brief history of the submarine service and an introduction into what it takes to become and live on a US. Nuclear submarine. There is some filming of the crew and operations with a couple of drills on a SSN. This brief glimpse is amazing considering how the service does not wish to share information on a weapon system that relies on secrecy. Having been on a nuclear submarine I can tell you that they filmed on an actual boat and if you are interested in modern submarines this is worth watching for the brief glimpse into that world.

2/5 Intro to nuclear submarine life
  by G. Wayne Hild (mars)
This video is a basic introduction to life on & in a nuclear submarine. It does touch & I mean touch lightly upon the earlier WW subs & some basic statistics about how they performed such a great part in the war against japan. If you are interested in a light glimpse into the nuclear sub except where only the priveledged are allowed then buy this dvd.

4/5 Good documentary

Although it is a bit short in length, this is a good documentary on subs, including some discussion of strategy.
