The year 1969 was devoted almost entirely to maintenance and training. On 27 January, "Wallace L. Lind" reported to the Norfolk Naval Shipyard, Portsmouth, Virginia., for regular overhaul which was completed on 10 June. The vessel spent a month in Norfolk preparing for "Project X-SI"; and on 24 July, she set course for San Juan for testing her new additions. The destroyer returned to Norfolk for the final evaluation of the project on 14 August. On 17 September, the ship arrived at Guantanamo for refresher training which lasted through 20 November. During the month of October, "Wallace L. Lind"’s home port was changed to Pearl Harbor effective on 1 January 1970.
