BAP Abtao (SS-42) is an Abtao-class submarine of the Peruvian Navy. The vessel which was originally named BAP Tiburón ("Shark"), was constructed by the American Electric Boat company in the United States and launched in 1953. The Abtao class were the last submarines constructed by the United States for the export market. The submarine entered service in 1954 and by presidential decree, was renamed Abtao for the battle during the Chincha Islands War. Armed with six 21-inch (533 mm) torpedo tubes and a 5 in (127 mm)/25 caliber gun, the 243 ft (74.1 m) submarine took part in the rescue of the crew of BAP Pacocha, another submarine that had sunk following a collision. Abtao was taken out of service in 1999 and converted into a museum ship located in Lima, Peru. Abtao was the first museum ship in Latin America.

Callao (Spanish pronunciation: [kaˈʎao]) is a Peruvian seaside city and region on the Pacific Ocean in the Lima metropolitan area. Callao is Peru's chief seaport and home to its main airport, Jorge Chávez International Airport. Callao municipality consists of the whole Callao Region, which is also coterminous with the Province of Callao. Founded in 1537 by the Spaniards, the city has a long naval history as one of the main ports in Latin America and the Pacific, as it was one of vital Spanish towns during the colonial era. Central Callao is about 15 km (9.3 mi) west of the Historic Centre of Lima.

The Battle of Callao (Spanish: Combate del Dos de Mayo, as it is known in South America) occurred on May 2, 1866, between a Spanish fleet under the command of Admiral Casto Méndez Núñez and the fortified battery emplacements of the Peruvian port city of Callao during the Chincha Islands War. The Spanish fleet bombarded the port of Callao (or El Callao), and eventually withdrew without any notable damage to the city structures, according to the Peruvian and American sources; or after having silenced almost all the guns of the coastal defenses, according to the Spanish accounts and French observers. This proved to be the final battle of the war between Spanish and Peruvian forces.
