ARA Santa Cruz (S-41)

History

The modern Argentine Navy has an active submarine force of only three submarines. These include the Santa Cruz-class ARA Santa Cruz (S-41) and ARA San Juan (S-42) and the Salta-class ARA Salta (S-31). The unit entered service in 1972 with the arrival of Salta, joined by Santa Cruz in 1985 and San Juan in 1987.

All three were active in the Argentine fleet.

The Santa Cruz class was developed in the 1980s based on the standard diesel-electric submarine "TR-1700" supplied by the German company Thyssen Nord Siwijk. They are completely conventional boats with basic functions and performance, like the diesel-electric boats of the Cold War era. Power is provided by 4 MTU diesel generator sets for surface driving and 1 Siemens electric motor for underwater operations.

The surface speed reaches 15 knots and 25 knots underwater. The surface voyage has a range of 12,000 nautical miles and the mission duration window is 30 days.

There are 26 crew members on board. The radar is a Thompson CSF "Calpso" unit and the sonar is handled by an Atlas Electronics CSU and a Thompson "Sintra" DUUX-5. Weapons include 6 x 533 mm (21") torpedo tubes and 22 reloads.

ARA Santa Cruz was completed on September 28, 1982 and officially opened on October 12, 1984. She made headlines in June 2014 when the ship ran aground near the Argentine capital, Buenos Aires. Other than that, there is little notable news about the Santa Cruz.
