Buenos Aires: An Argentinean submarine has lost contact in the South Atlantic with 44 crew on board, military authorities said.
The ARA San Juan was carrying out a surveillance mission in Argentina’s exclusive economic zone near Puerto Madryn, around 1,400 km south of Buenos Aires, Xinhua news agency reported.
Argentina’s naval commander for the Atlantic, Gabriel Gonzalez, told the media on Friday that radioelectrical communication was lost with the submarine ‘48 hours ago’.
The last communication with the craft happened on Wednesday.
Navy spokesman Enrique Balbi denied that it had been found.
Answering rumors about the submarine, Balbi said that news of a fire on board was ‘not official information’. 
‘There may have been a technical fault, there is no communication yet.’
The Foreign Ministry also issued a statement, saying ‘the governments of Chile, the United States and the United Kingdom have offered logistical support and exchange of information in this humanitarian search’.
Three planes, four ships and one helicopter are searching the area for the missing submarine. 
The ARA San Juan is a TR-1700 submarine made in Germany, which joined the Argentinean navy in 1985.
