Abtao-class submarine
The Abtao class were four submarines of the Peruvian Navy that entered service between 1954 and 1957. They are also known as the Lobo class and the Dos de Mayo class and were constructed in the United States to a design based upon the United States Navy's Mackerel class. They were the last submarines to be constructed by the United States for the export market. All four submarines were powered by a diesel-electric system and armed with six 21-inch (533 mm) torpedo tubes. Two of the submarines also mounted a 5 in (127 mm)/25 caliber gun. The four submarines, initially named for animals, were all renamed in 1957 for famous Peruvian battles. Beginning in 1991, the submarines were taken out of service, with the last decommissioned in 1999. One, BAP Abtao, is a museum ship located in Lima, Peru.
