Project history

Contracted on 30 November 1977. Initially Argentina was to acquire four Type 1700s and two TR 1400s (a smaller version), but in 1982 the order was changed to six of the larger type. First two German-built boats completed and delivered in 1984-85, while other two being built in Argentina (from 80%-prefabricated German-built parts) were suspended pending funding and in 1986 permission was given by German partner to sell all these submarines to a third country, but buyer was not found. Their building readiness was 52% for S43 and 30% for S44 in 1994. Planned building of S45 and S46 was never begun. These are very advanced and fast diesel-electric submarines. Fitted with torpedo auto-reload system allowing the reloading of the torpedo tubes in 50 seconds. Endurance is 30 days.

Modernizations

None.
