In this episode, Garrison is rejoined by returning guest and renowned maritime security analyst, Dr. Collin Koh.  The two embark on an informative discussion regarding the maritime strategic implications of the AUKUS deal to the Indo-Pacific, from why nuclear submarines are significant, to the nature of Australia as a geopolitical linchpin in Washington’s counter-China strategy. They also discuss Russia’s testing of a sub-launched Zircon hypersonic missile, how this fits into the historical Soviet-Russian naval strategy to counter the United States, and what this class of weapons means for the future of networked fleet defenses in space and cyberspace specifically, and naval competition more broadly, in the Indo-Pacific.
