The fifth Grayling was laid down at the Portsmouth Naval Shipyard, Portsmouth, N.H., 12 May 1964; launched 22 June 1967; sponsored by Miss Lori Brinker, daughter of Lt. Comdr. Robert Brinker, who commanded Grayling OSS-209) when she was lost in action; and is to commission in the spring of 1968. Once commissioned, she will become a key element in the under-water deterrent force of the Navy and will contribute to the vital, continuing task of "keeping the peace" over the vast reaches of global waters. Designed to attack and destroy all types of enemy ships, she can operate for long periods at great depths and at high submerged speeds, making her a potent and effective challenge to enemy submarines. Operating under nuclear power, she can conduct long-range reconnaissance patrols and surveillance missions without risking detection by surface ships. Moreover, she is designed to carry out extensive ASW operations, either alone or with other fleet submarines and destroyer-type surface ships.
