World War II Pacific Theatre operations
From 20 December 1942 to 4 March 1943 Constant escorted convoys between San Francisco, California, and Pearl Harbor. She sailed from Pearl Harbor 8 March for Espiritu Santo, arriving 25 March for local escort duty, operating from Espiritu Santo and Noumea in support of the Guadalcanal operation.
On 3 September 1943 she arrived at Tulagi and remained in the Solomons on inter-island escort and minesweeping duty with occasional convoy voyages to Nouméa and Espiritu Santo until 3 April 1944 when she steamed to Auckland, New Zealand for a brief overhaul. She returned to Port Purvis in the Solomons 13 May.
Reclassified as a submarine chaser
She then returned to Pearl Harbor, where she was decommissioned 19 June 1946. Assigned to the 14th Naval District for Naval Reserve training 28 October 1946, PC-1590 was placed in commission in reserve 5 May 1950, and in full commission from 20 March 1951 until decommissioned 22 October 1954.
