From 1958 to 1962 the LST excelled in training and experimental amphibious operations in the Atlantic, Caribbean, and on two occasions the Mediterranean. Following operations with Marines at Camp Pendleton in October, 1962 Grant County was dispatched to Florida for assignment during the Cuban Missile Crisis. When the crisis eased, Grant County resumed her training, and remained on alert in the event of another flare-up.

On 3 October she sailed for another Mediterranean deployment and participated in amphibious exercises before returning home 31 March 1966. During the next four months Grant County participated in intermittent amphibious exercises along the Atlantic Coast and in the Caribbean.
