Just a heads up for any state side folks that get PBS. I saw the previews and it looks like an interesting episode.

Nazi Mega Weapons

About Hitler's Killer Subs (Premieres Wednesday, June 22, 2016)

By early 1943 Nazi Germany is losing the battle in the Atlantic. Their U-Boat menace is no longer invulnerable to attack; it could cost them the war. But Hitler and Kriegsmarine High Command are one step ahead. Since 1940, they’ve been planning a submarine capable of fast underwater speeds and phenomenal firepower that will outperform anything that has gone before. Designated the Type 21, it’s the world’s most advanced submarine: Hitler’s sea-faring super weapon.

Looks like you can watch the full Blitzkrieg previous episode here:
