HMS Astute Followed America's Nuclear Carrier for 3 Days. The US Navy Never Knew.

The United States believed the Royal Navy's submarine fleet could no longer compete with the world's most advanced attack submarines. Then HMS Astute quietly disappeared beneath the North Atlantic. What followed during a classified NATO anti-submarine warfare exercise stunned even experienced submariners. While America's Virginia-class attack submarine searched the ocean, HMS Astute had already taken position, silently tracking its opponent for days before achieving a simulated kill. In this documentary, we examine the tactics behind one of the most remarkable modern submarine encounters ever discussed. From early deployment and acoustic shadowing to thermoclines, sonar warfare, and the final exercise kill, this is the story of how patience, positioning, and strategy challenged one of the world's most capable submarines.
