The American Nimitz-class aircraft carrier USS Theodore Roosevelt was theoretically sunk by a foreign submarine in 2015. In this case, it was one of France’s absurdly heavily armed Rubis-class nuclear-powered submarines that “sank” the carrier, during a joint exercise in the North Atlantic.

The mighty super aircraft carrier may be vulnerable to “lesser” tech, specifically, the Rubis-class submarine, which “sank” an American carrier during a war game in 2015.

Although details of how the Saphir - a Rubis-class submarine -  was able to detect and attack Theodore Roosevelt quietly remain a mystery, the French submarine was successful in slipping into the Nimitz-class carrier’s defensive screen while avoiding detection by ASW assets.

In 2015, the Saphir, a French Rubis-class submarine, participated in a war game with U.S. Carrier Strike Group 12. The U.S. Navy would love to forget it.
