The 3rd Fleet was recreated once again on 10 April 1941 with the additional designation "Southern Expeditionary Fleet" for the specific task of invading the Philippine islands. At the time of the attack on Pearl Harbor, its headquarters was in Palau and its mission expanded to include the invasions of Java, Borneo and other islands of the Netherlands East Indies. It was superseded by the 2nd Southern Expeditionary Fleet under the aegis of the Southwest Area Fleet on 10 March 1942.
