Pacific Ocean operations edit

Satinleaf arrived at San Pedro, California, on 9 May 1944 for shakedown, and sailed from there on 13 June 1944 to join the Service Force, U.S. 7th Fleet, at Funafuti, traveling via Pearl Harbor.

On 27 July, she departed Funafuti towing an Army barge which she delivered to Milne Bay, New Guinea, on 6 August. She was employed there as a harbor defense and general utility vessel until 1 October, departing the harbor only to deliver a barge to Manus between 18 and 25 September.

Supporting invasion of the Philippines edit

On 1 October, the ship sailed for Brisbane, Australia, where she loaded sonar buoy equipment for use in the forthcoming assault at Leyte Gulf. Picking up personnel for the buoy unit at Milne Bay on 15 October, she arrived at Leyte on 29 October, shortly after the landings.

The ship began laying the sonar buoys on 5 November 1944, and guarded them until 17 January 1945, providing protection to ships anchored off Leyte. On 20 January, she became Harbor Entry Control Vessel and performed that duty until 12 March. Then, for the next month, she was employed in general utility work in San Pedro and Guiuan Roadstead and assisted part-time with the Guiuan Roadtead net defenses.

Supporting Tarakan landings edit

On 15 April 1945, Satinleaf was assigned to the Amphibious Forces, 7th Fleet, and sailed a week later with navigation buoys for the Tarakan landings. Arriving off Tarakan, Borneo, on 27 April, she laid navigation buoys to guide the assault ships along the cleared channel.

This mission was completed on 30 April, and the ship sailed on 8 May for Morotai where she staged for the Brunei landings. Arriving off Brunei, Borneo, on 7 June, she once again laid navigation buoys in the channel; and, after completion of this duty on 9 June, she remained in the area providing general utility services until departing for Leyte Gulf on 25 June. She helped install net defenses in Guiuan Roadstead until sailing to Manus on 12 July for overhaul.
