Named after the muskallunge, a rare species of fish which can be found in the waters surrounding North America, the submarine came to life in 1942 as a Gato-class ship. It was sponsored by Mrs. Merritt D. Graham, widow of Chief Torpedoman Graham who was lost in Grunion (SS-216) during the same year as the submarine was built. The USS Muskallunge was commissioned in 1943 and completed 7 war patrols, for which it earned 5 battle stars. Asbestos was present on the vessel in large amounts, since it was widely employed in shipbuilding due to its convenient properties, such as fire resistance. This represented a great health hazard for those who served on the submarine, which is why we strongly recommend them to undergo periodical medical examinations to prevent the development of serious diseases like mesothelioma or lung cancer. In 1957, the USS Muskallunge was transferred to Brazil and sunk as a target 11 years later.
