BAP Carvajal (FM-51) is the first out of four Carvajal class frigates ordered by the Peruvian Navy in 1973. It was built by the Italian shipbuilder Cantieri Navali Riuniti at its shipyard in Riva Trigoso, Genoa. Though sea trials were initiated on June 9, 1977 its commissioning was delayed until December 23, 1979 due to delays in equipment deliveries by some subcontractors. In 1998 her flight deck was extended to allow ASH-3D Sea King helicopters to land and refuel, even though they can't be housed in the ship's hangar.
