After several weeks of type training, the ship spent July, August, and September taking part in ASW Exercise "Fixwex Golf 67"; Operation "Lash Out," a NATO exercise which simulated an attack on the east coast; as well as various other exercises and tender availability. On 3 October, "Wallace L. Lind" arrived at the Boston Naval Shipyard to have a special sound source installed in place of the variable depth sonar. She then headed for the Bahama Islands to take part in Operation "Fixwex I," an exercise designed to measure submarine and task group noise levels. The destroyer spent the remainder of 1967 undergoing availability and in leave and upkeep. During this period, the special sound source was removed, and the ship was returned to her original configuration.
