After a brief period of operations and supplementary overhaul in San Diego, "Catamount" sailed on 25 June on a special mission, carrying landing craft to southern Chile, devastated by the Great Chilean earthquake. Transferred to the Chilean Navy, these landing craft provided critically needed transportation in regions where piers had been destroyed by tsunami. "Catamount" returned to San Diego on 13 August, operated on the west coast and on 22 November sailed for another tour with the U.S. 7th Fleet in the Far East.
