During the 1960s Argentina sought to replace its aging fleet of tanks, which included British Sherman V Firefly tanks and American M3A1 half-tracks dating from shortly after the Second World War. In their attempts to procure equipment from the United States, Argentina could only secure 50 M41 Walker Bulldogs (undelivered) and 250 M113 armored personnel carriers. When the United States turned down requests for further equipment, the Argentine government turned to the other side of the Atlantic, putting their "Plan Europa" (Plan Europe) into action. It was hoped that European technology could stimulate Argentine industry so the country could produce its own armaments in the future. Argentina procured 80 AMX-13 light tanks, as well as 180 AMX-VCIs and 24 AMX-155 F3s, from the French government, manufacturing around 40 AMX-13s and 60 AMX-VCIs at home. The French AMX-30 and German Leopard 1 were also examined as possible replacements for the Argentine Sherman fleet.
