With most of the war patrols it conducted successfully, the USS Halibut was awarded 7 battle stars for World War II service and sunk 12 enemy ships. It was laid down in 1941 by Portsmouth Naval Shipyard and launched during the same year. However, because it was laid down at the time when asbestos was widely used in shipbuilding, the carcinogenic mineral was most likely present in the wall insulation of the submarine. Therefore, veterans who served on the USS Halibut are strongly advised to undergo regular medical examinations to make sure the asbestos fibers they breathed in have not damaged their lungs. The submarine was struck from the Naval Vessel Register in 1946 and subsequently sold for scrap.
