I do love me some hot Navy action. I also really enjoyed The Hunt For Red October. So:
“Co-ordinated Anti-Submarine Warfare” This is labeled as part 1, but I think the good folks at PeriscopeFilm put parts 1 and 2 together when they uploaded the newly mastered version.
Bonus video: “Tracking the Threat: Anti Submarine Warfare in the Cold War”. This has a 1982 copyright date, which makes it extremely contemporary with Red October.
