These evolutions in Hawaiian waters proved to be the last for some time; "Anderson" got underway for the West Coast of the United States shortly after noon on 24 March, and reached Mare Island Navy Yard on the last day of the month after first disembarking, at San Francisco, enlisted passengers transported from Pearl Harbor. The destroyer spent all of April 1941 undergoing repairs and alterations at the West Coast yard, and on 16 May got underway for her post-repair trials.
