[Ed. – This isn’t likely to end well. The submarine, S-42, is a German-built TR-1700 diesel-electric boat commissioned in the 1980s. The Argentine navy takes reasonably good care of its assets. But submarine accidents do happen.]
A NASA research aircraft has joined in the search for a missing Argentine submarine and its crew of 44, a defense official told USNI News on Friday.
The NASA P-3 Orion is now looking for the diesel-electric attack boat ARA San Juan (S-42), which has not been heard from since Wednesday, according to press reports from the region.
In addition to the U.S. P-3, the Argentine Armada has dispatched destroyer ARA Sarandí (D-13), and corvettes ARA Rosales (P-42) and ARA Drummond (P-31). …
The submarine departed from the Argentine Armada naval base in the southern city of Ushuaia, located southwest of the Strait of Magellan, and was headed to its homeport at Mar del Plata, near Buenos Aries. The submarine was last heard from about 250 miles off of Patagonia.
