Families of the missing 44 crew aboard the missing Argentine submarine are starting lose hope that the ARA San Juan will be found after losing contact with it on November 15th. There is acoustic evidence that an explosion occurred just three hours after the captain called in to report a power system failure that he believed was adequately repaired. The submarine was expected to submerge and proceed towards Mar del Plata. The ARA San Juan was built in Germany in 1983 and had a range of 22,224 km and top speed of 45 km/h. Included in the crew is 35 year old Eliana Maria Krawczyk, the first female officer in Argentina to serve on a submarine.
