The Espora class (MEKO 140A16 type) corvettes were all commissioned between 1985 and 2004 for the Argentine Navy, the first four (P-41 to P-44) in 1985-1990 and the last two (P-45/46) in 2001-2004.

Based on a design by the German shipyard Blohm + Voss, all the ships of the class were built in Argentina at the “AFNE Rio Santiago” shipyard, in close to the city of La Plata, province of Buenos Aires. Contract was signed on August 1st 1979. Although considered by its designers to be frigates, the Espora class vessels have been classed in Argentina as corvettes.

The ships currently serve in the High Seas Fleet (“Flota de Mar”) of the Argentine Navy, based on Puerto Belgrano Naval Base, close to the city of Bahia Blanca, province of Buenos aires, Argentina.
