War Questions: Just How Effective Are Submarines Against Aircraft Carriers?

Hit and Sunk: A Swedish Submarine Killed an Aircraft Carrier During a War Game

In 2005, USS Ronald Reagan, a newly constructed $6.2 billion dollar aircraft carrier, sank after being hit by multiple torpedoes. This first appeared earlier and is being reposted due to reader interest. Fortunately, this did not occur in actual combat, but was simulated as part of a war game pitting a carrier task force including numerous antisubmarine escorts against HSMS Gotland, a small Swedish diesel-powered submarine displacing 1,600 tons. Yet despite making multiple attacks runs on the Reagan, the Gotland was never detected. This outcome was replicated time and time again over two years of war games, with opposing destroyers and nuclear attack submarines succumbing to the stealthy Swedish sub.

In 2005, USS Ronald Reagan, a newly constructed $6.2 billion dollar aircraft carrier, sank after being hit by multiple torpedoes. Here s What You Need to Remember: Diesel submarines are ideal for patrolling close to friendly shores. But U.S. subs off Asia and Europe need to travel thousands of miles just to get there, and then remain deployed for months at a time. A diesel submarine may be able to traverse that distance but it would then require frequent refueling at sea to complete a long deployment.
