Federal police officers have raided naval bases and other buildings in Argentina as part of an investigation into the disappearance of a submarine with 44 crewmembers.

Friday's raids were ordered by Federal Judge Marta Yanez.

She tells local TN television that she wants to review documents focused on the condition of the vessel before it began its journey. She also says that she wants to look into possible faults in the midlife refit of the submarine.

A blast occurred near the time and place where the ARA San Juan went missing Nov. 15. Argentina gave up hope of finding survivors, but the navy has continued searching for the vessel.

The sub was commissioned in the mid-80's and was most recently refitted between 2008 and 2014.
