Rarely has the delivery of a warship to a "lesser developed" nation generated as much discussion in naval circles as that created by the December 1984 arrival in Argentina of the ARA-type (Armada Republica Argentina) TR1700 submarine Santa Cruz. Built specifically for ocean operations using hydrotechnology previously found only in nuclear submarines, the Santa Cruz is the first of a wave of third-generation diesel electric submarines-boats having the potential to revolutionize the navies that acquire them.
