The USS Torsk was the last US Navy submarine to sink an enemy warship until the war with Iran. Take a look inside.

Torsk may seem like an outdated museum relic, and for the US Navy, it is. For other countries with less advanced naval forces, however, it would still be a powerful asset.

Take, for instance, Torsk’s sister ship, the USS Cutlass, which was commissioned in 1945. While Torsk became a museum in 1972, Cutlass was sold to Taiwan in 1973 and is still operational in the Republic of China Navy.

“This is still a relatively state-of-the-art piece of equipment relative to the world — not compared to our Navy, but compared to, say, the Iranian navy, this is very state-of-the-art,” Auer said, standing in Torsk’s after torpedo room. “The Iranians don’t have anything like this.”
