Design
The submarine was designed by Thyssen and its features include high underwater speed, endurance, and survivability. The ship's four MTU diesel engines, four generators, and Siemens electric motor can propel it for speeds up to 25 knots (46 km/h; 29 mph). Eight 120 cell batteries are installed on the ships. They have a diving depth of 300 m. Normal endurance of these ships is 30 days with an extended range up to 70 days. These ships are equipped to accept a Deep Submergence Rescue Vehicle (DSRV). Armaments include six bow 533-mm torpedo tubes and 22 SST (Special Surface Target) or Mark 37 torpedo. The automatic torpedo reload system can reload the tubes in 50 seconds.
The Argentine Navy requested that INVAP develop the CAREM nuclear reactor to power these submarines, but the program was halted in late 1980s.
Thyssen proposed the TR1700A for the Collins-class submarine program. The proposed design had an reworked pressure hull, was six meters longer, and half a meter wider than the TR1700's for Argentina. It lost to the Type 471 from Kockums, an enlarged Västergötland-class submarine.
