In this episode of the US Navy History Podcast, hosts Dale and Christophe delve into a significant event from 2005 that served as a wake-up call for the US Navy. The episode recounts how the Swedish submarine HMS Gotland, employing Air Independent Propulsion (AIP), managed to stealthily breach the defenses of the USS Ronald Reagan during military exercises, simulating multiple torpedo kills. This humbling experience led the US Navy to lease the Gotland for two years to better understand its silent stealth capabilities and to incorporate those lessons into their own anti-submarine warfare strategies. The discussion elaborates on how this event spurred significant changes in naval training, tactics, and strategy, influencing the future of undersea warfare globally. The episode concludes with a tribute to Sergeant Major James G. Ryan Sartor, a decorated Green Beret who made the ultimate sacrifice in Afghanistan.
