Hunt for the samurai sub
 

National Geographic the past year aired a documentary about the five IJN submarines, taken as prize of war, and later scuttled in 1946 near Oahu.

Two large carrier subs of the Sentoku type, one smaller carrier of the AM type and two fast attack sub of the Sentaka type.

Does anybody know if there's a DVD (or better) a Bluray available of this particular documentary? it should be called the "The National Geographic Expedition Week 2009"
