Following this operation, the ship resumed her runs between Nouméa and Guadalcanal and continued that duty until departing Guadalcanal on 24 March 1944, bound for Hawaii. Following a stop at Funafuti, Ellice Islands, en route, she reached Hawaii on 9 April. Throughout April and May, "Alhena" conducted maneuvers and loading operations in Hawaiian waters in preparation for the impending assault on Saipan. She departed Honolulu on 30 May with troops of the 2nd Marine Division embarked, bound via Eniwetok for Saipan. "Alhena" arrived off Saipan on 15 June and began debarking her troops. Despite undergoing two air attacks while unloading, she completed the process on the 23d, left the area, touched at Pearl Harbor on 4 July, and pushed on the next day toward the California coast. The ship entered San Francisco Bay on the 11th and, shortly thereafter, began a three-month period of overhaul.
