The "ARA San Juan" submarine disappeared in November 2017 while on patrol in the exclusive economic zone. The vessel was found a year later at over 900 meters deep and 500 kilometers off the coast of Comodoro Rivadavia city.
Senate National Defense Commission President Nancy Gonzalez regretted both that the submarine "was not scouted for a long time" and that the search was undertaken in an irregular manner.
"On Nov. 15, 2017, our country suffered the greatest naval tragedy in peacetime... I hope justice will soon rule to hold the responsible accountable," she stressed.
