Cross section a TR 1700 which identifies the most important sections as part of its propulsion system (Art: Adrian Duenas / Source: www.histarmar.com) The acquisition of fifth-generation submarines represented a quantum leap important for Armada Argentina and was part of a project which gave a superlative importance to the Submarine Force within the framework of naval weapon. The original plan conceived to complement the recently acquired IKL Type 209 submarines with 6 (six) modern oceanic units of the TR 1700 Nordseewerke Thyssen, whose hull design specifications were made anticipating potential future changes in their propulsion, from diesel-electric nuclear.

Political changes, the cyclical economic crises, and the apathy and lack of strategic vision by successive governments, made the original project remain unfinished.

Closure and sale of the shipyard in 1996 (Carlos S. Menem administration) the latter were cannibalized for spare parts serve to both TR 1700 on active duty, as well as different equipment for them come from Germany.

His helmet, special hydrodynamic design, features a low profile and free of bumps, which allows optimal displacement under the sea surface, while it becomes quieter and less detectable by sonar.

The armament consists of 22 torpedoes SST-4 fiber-optic guided reviewed.

The interior space, is designed to optimize the useful areas, allowing interior comfort than their predecessors, but also limited.

Both submarines have their base of operations in the Base Naval Mar del Plata (BNMP) and together with the ARA Salta (S-31) make up Current Submarine Force Armada Argentina.

Albornoz) During 2010, government sources, there was the story that one of the unfinished TR 1700 could reach completion to fulfill an old dream of the Armada Argentina the have a nuclear powered submarine, meeting the other hand the original project estimate. The modular nuclear reactor CAREM (short for Modular Elements of Central Argentina), in advanced stages of development the INCAV / CNEA, would be installed in the incomplete ARA Santa Fe (S-43) , even though it is more wishful thinking which resulted from an announcement by the then defense minister, Nilda Garre, a reality that concrete.
