Engage arrived at Charleston, South Carolina, on 12 December 1942 from her shakedown off Florida, and cruised again to Florida ports the next month on coastal escort duty. She arrived at Norfolk, Virginia, on 4 February 1943 for operations in Chesapeake Bay until 10 March, when she sailed on escort duty to Bermuda. Here she served on escort and patrol duty, as well as training with submarines, occasionally leaving the area to escort ships to Norfolk.

On 4 July 1944, PC-1597 sailed in convoy from Norfolk, Virginia, for Bizerte, Tunisia, arriving 23 July. She moved on to Naples, Italy, and Ajaccio, Corsica, from which she cleared 13 August for the invasion of southern France. During the initial assault, she acted as reference vessel for the waves of landing craft bringing the troops ashore, then patrolled off the transport area. Through the next month, she supported the buildup in southern France by escorting convoys to the beachheads, and patrolling along the Riviera. At the close of September, she began general escort duty in the western Mediterranean until 27 May 1945 when she sailed for Jacksonville, Florida.

She was decommissioned on 19 November 1945 at Jacksonville, Florida, and transferred to the Maritime Commission on 8 November 1946. Transferred to the Dominican Republic in 1946 as Cibao (P103), renamed and reclassified Constitución (P203), and placed out of service in 1961. Fate unknown.

PC-1597 received one battle star for World War II service.
