In this episode Angus is looking at Japanese submarine operations in the Pacific during the early part of the war. While we're sure you’re all familiar with the Imperial Japanese surface fleets actions during 1941-42, especially if you’ve listened to the discussions with Jeff Cox in episode #14and #63, but there seems to be very little mention of submarines. Which is interesting because if we look at the Battle for the North Atlantic it was all about the German U-Boats.

Joining Angus today is Mark Stille.

Mark is a retired US Navy commander, alumni of the US Naval War College and author of numerous Osprey titles, mainly focusing on the war in the Pacific - his latest being USN Fleet Destroyer vs IJN Fleet Submarine.
