Leading Seaman Arjona, age 32, was married with two daughters and lived in Mar del Plata for ten years.
On November 15, 2017 the Argentine submarine ARA San Juan (S-42), a TR-1700-class diesel/electric vessel, disappeared off the coast of Argentina while on a training exercise. There were 44 submariners aboard. On that day of its last contact, the Comprehensive Nuclear Test-Ban Treaty Organization, which has a network of listening posts to monitor nuclear explosions, said that it had detected a "hydro-acoustic anomaly" near the sub’s last known position.
Also on that date, commander Gabriel Galeazzi reported a “short circuit" in the vessel's batteries caused by saltwater entering the submarine's snorkel and dripping on to a battery tray in the prow, which caused the battery to short circuit and smolder. The submarine was ordered back to port but was never heard from again.
More than a dozen countries either offered supplies and support or participated in search and rescue operations.
In November 2018 the wreck was located. The submarine had imploded and was broken into pieces due to water pressure and is lying at a depth of 2,975 feet (907 meters), meaning future recovery is likely impossible.
