ARA Rosales (P-42) is the second ship of the MEKO 140A16 Espora series 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 operational status of Rosales is not clear, as of November 2012 she was waiting for spares.
