The TR-1700 (Santa Cruz) is a class of diesel-electric patrol submarines built by Thyssen Nordseewerke for the Argentine Navy in the 1980s, with two submarines completed. These ships are amongst the largest submarines built in Germany since World War II and are among the fastest diesel-electric submarines in the world.[3] ARA San Juan was lost on 17 November 2017, leaving ARA Santa Cruz as the only remaining submarine of this class. As of 2020, the refit of Santa Cruz has been reported cancelled leaving the entire class inactive.[4][5]
