The USS Dace participated in World War II and won 7 battle stars, having been laid down in 1942 by the Electric Boat Company in Connecticut. It completed 7 war patrols, 5 of which were declared successful. The submarine sunk a total of 28,689 tons of Japanese shipping during its activity. Because it was built during a time when asbestos was a very popular insulating material, the carcinogenic mineral was present on the USS Dace in considerable amounts. For the reason, people who served on this submarine need to pay close attention to their health and undergo regular medical examinations. The vessel was struck from the Naval Vessel Register in 1972, after having been transferred to Italy, where it entered the Greater Underwater Propulsion Power Program (GUPPY).
