A US Navy aircraft located a heat signal 230 feet below the surface that seems to indicate that a submarine missing since last Wednesday may have been located. Rescue ships in the surrounding area reports hearing sonar signals. The submarine has an estimated seven days worth of oxygen and every hour of the search and rescue is precious.
The Argentine submarine known as the “San Juan” was coming back from a routine mission in the southern Atlantic. The crew of 44, including two of the first women submariners, were last heard from on Wednesday and concern began to grow as the days went on.
According to experts, as long as there wasn’t a hull breach, the crew should have seven days worth of oxygen available without coming to the surface. Some experts have extended the initial projection to 10 days.
One day before the submarine went missing, a video showed the submarine traversing storm waves. An international search party began which included countries such as Brazil, Britain, Chile, the United States and Uruguay.
The recent storms have slowed the search down significantly and minimized the possibility of boat searches. There have been numerous possible sightings in the week the submarine went missing.
A British ship using sonar thought it had communicated with the missing submarine, but experts dismissed the possibility days after it was reviewed.
A U.S. Navy P-8 aircraft thought it spotted white flares one night in the suspected area of the search but were later informed that the San Juan only carried red and green flares. It wasn’t until Tuesday night that tangible evidence of the San Juan’s location begin to gain traction.
A U.S. aircraft discovered a heat signal 186 miles off the coast, according to the Daily Mail. The heat signal would indicate a large metal object beneath the depths of the surface.
Since the possible location of the San Juan has been located, U.S. rescue ships have been deployed from San Diago, California.
NASA has also sent an Antarctic P-3 Poseidon surveillance aircraft to help zero in on the submarine’s location. The San Juan is one of three of Argentine’s submarines.
