ARA Rosales (P-42) is the second ship of the MEKO 140A16 Espora class of six corvettes built for the Argentine Navy. The ship is the fourth ship to bear the name of Colonel (Navy) Leonardo Rosales, who fought in the Argentine Navy during Argentina's war of independence and the Cisplatine War.
The Argentine Navy struggles to meet maintenance and training requirements because of financial problems and import restrictions. The availability of spare parts was a problem as of 2012[2] and by 2019 she was reported in reserve and to be scrapped.[3] However, in 2021 she underwent repair work at the Tandanor shipyard and returned to service in 2022.[4][5][6]
Rosales and her sister ships were part of the 1974 Naval Constructions National Plan, an initiative by the Argentine Navy to replace old World War II-vintage ships with more advanced warships. The original plan called for six MEKO 360H2 destroyers, four of them to be built in Argentina, but the plan was later modified to include four MEKO destroyers and six corvettes for anti-surface warfare and patrol operations.
