San Luis reported two attacks on Royal Navy ships during the war. On 1 May, the frigates
Brilliant and Yarmouth were sent to hunt down
San Luis operating north of Stanley . San Luis reported firing a German-made SST-4 torpedo, on purely passive sonar detection of British gas turbine powered warship(s) and Sea King 's searching. The torpedo which presumably missed its target, due to range, malfunctioning of the computer fire control system, gyro misalignment and the breakage of the wire guidance wire. Nevertheless experts believe that a closer range attack or alternative use of the MK 37 in an anti-ship role might have been successful. [4] Sonar operators aboard Brilliant were certain they heard and confirmed the sound of an SST-4, and Brilliant, Yarmouth and three Sea Kings from Hermes 's 826 Squadron
[5] launched depth charge, mortar and torpedo attacks for 20 hours [6] until the short sub-Antarctic night on 1 May. Searching for the Type 209 submarine was hindered by the numerous wrecks of whaling boats and whales, indistinguishable from submarines. San Luis however had adopted the tactics of 1944-45 German U-boats and rested on the bottom, [7] shut down and invulnerable to attack, some distance from the area of interest to the British frigates. [8] During the short Falklands war, the United States supplied 200 Mk 46 torpedoes to the Royal Navy which expended 50 Mk 46 torpedoes during the war [9] against sonar detection of the possible sound of the single Type 209 submarine. The Royal Navy never detected or located the submarine, [10] which was in among the fleet, [11] but which weapon system effectiveness had been limited by British Intelligence. [12]
San Luis attacked again on the night of 10 May. The frigate Alacrity had made passage up
Falkland Sound, sinking an Argentine merchant navy ship on the way. As Alacrity left the channel before dawn, sister ship Arrow was waiting to accompany her back to the Task Force. San Luis detected the two ships and fired two SST-4 torpedoes, one of which did not leave its tube; the other was apparently defeated by Arrow 's anti-torpedo measures. [13] There were several problems with torpedoes and torpedo systems; in particular it appears that the torpedoes were not prepared properly, and did not arm themselves after firing, so would not explode even if they did hit a target. It has been suggested that previous apparent misses could have been due to torpedoes which struck home but did not explode. [13] After the Falklands War ended, German and Dutch engineers were sent to Argentina to discover what went wrong with their torpedoes. The problem was so simple as to be unbelievable: one of the Argentine sailors who was in charge of periodic maintenance of the torpedoes had inadvertently reversed the polarity of power cables between the torpedoes and the submarine. This meant that when the torpedoes' gyros were spun up, they ran "backwards" and thus tumbled on launch, preventing the weapons from taking up their proper heading.[14][15]

ukratko izvrsen je napad na dva broda i oba puta neuspjesno. razlog je u neodgovarajucem odrzavanju torpeda.
