MEKO 140

The MEKO 140 is a frigate/corvette design by the German Blohm + Voss shipyard as part of the MEKO family of vessels. The MEKO 140 is a development of the Portuguese Navy's João Coutinho-class corvettes designed by the Portuguese naval engineer Rogério de Oliveira in the late 1960s – three ships of which were built Blohm + Voss in 1970, as an outsourcing.

Concept and development
MEKO is a concept in modern naval shipbuilding based on modularity of armament, electronics, and other equipment, aiming at ease of maintenance and cost reduction. Vessels of similar classes can use different weapons systems, as required by the customer. The MEKO 140 was designed in the late 1970s, and was chosen by the Argentine Navy to complement the MEKO 360 destroyers.

Variants
Six vessels of the MEKO 140 A16 variant were constructed in Argentina by the Río Santiago Shipyards (AFNE) near La Plata for the Argentine Navy. They are locally named as the Espora-class corvette and currently serve in the High Seas Fleet ("Flota de Mar").

Although considered by its designers to be frigates, the Espora-class vessels have been classed in Argentina as corvettes.
