Torpedoes vs missiles, tomahawks vs smart bombs, fluid mechanics, missions ranging from direct combat to attack to surveillance... turns out, submarines and military aviation have much in common!

On this episode marking the U.S. Navy's 250th anniversary, former submarine commander Tony Grayson explains submarines for dummies, invoking aviation concepts and comparisons.

If your knowledge of subs is based on Crimson Tide, The Hunt for the Red October, or even Down Periscope, you might be pleasantly surprised how close to reality these epic movies come!
