While en route south, the ship held training exercises, and reached San Diego on 13 May, and continued shakedown in the San Diego area through 18 June. The next day, Alpine left San Diego and arrived at Pearl Harbor on the 25th. Soon thereafter, she began onloading the personnel and equipment of the 77th Army Division. On the 28th, Alpine was attached to Transport Division 38. With 1,417 troops embarked, Alpine sailed on 30 June to support the seizure of Guam. Her first stop was Eniwetok, which she reached on 9 July. A week of debarkation exercises was followed by a few more days of replenishment of supplies. The ship at last set off for the Marianas on 17 July and began offloadmg her assault troops and equipment off the west coast of Guam on 21 July. For six days, the transport remained in the area providing support to her landing party on the beach. At 1544 on 27 July she began her journey back via Eniwetok to Pearl Harbor. She reached Hawaii on 7 August and commenced voyage repairs.
Alpine's next assignment was to carry troops to support the invasion and occupation of Leyte. On 27 August, with 1,416 soldiers on board, the transport left Pearl Harbor for one week of amphibious training exercises off the island of Maui. She returned briefly to Pearl Harbor but got underway again on 15 September. Alpine made a three-day stop at Eniwetok for supplies and then continued on to Manus in company with Task Group (TG) 33.1. She arrived there on 3 October and began unloading troops to several smaller landing craft. On 14 October, Alpine got underway with TG 79.1 to Leyte with 791 troops embarked. Early in the morning of 20 October, she arrived in Leyte Gulf and, at 0830, commenced the debarkation of her troops. Throughout the day, she unloaded supplies and received casualties. On the 21st, despite intermittent air attack warnings, she finished offloading her troops. The transport left Leyte at 2000 bound for Hollandia, New Guinea.
Alpine stood into Humboldt Bay on 26 October and transferred casualties to a hospital at Hollandia. She took on board provisions and fuel and then got underway on 5 November for Biak in the Schouten Islands. There, the transport loaded the headquarters squadron of the 5th Army Air Force and, on 14 November began the return voyage to Leyte Gulf.
At 0728 on 18 November Alpine commenced debarking troops. She soon spotted an enemy aircraft, and the transport's gunners opened fire from a range of 3,000 yards. The plane banked to the right and was observed splashing off the starboard quarter. Later, a second Japanese plane approached; and Alpine again opened fire. The plane was hit forward of the tail assembly, which exploded and left a trail of black smoke as the plane commenced a bank to the left and went into a full power dive toward Alpine's bridge. At an altitude of 1,200 feet, the aircraft burst into flames but still crashed into the attack transport's port side Two explosions produced a column of flame, and debris arose. Firefighting crews brought the flames under control in one-half-hour. Five crew members were killed and 12 injured. Alpine finished unloading her troops and cargo, left the area at 1810 and retired to Manus.
The transport anchored in Seeadler Harbor on 24 November and underwent hull repairs necessitated by her battle damage. On 1 December, she shifted to Finschhafen, New Guinea, and embarked 1,512 Army troops and their equipment. Alpine then participated in tactical and antiaircraft gunnery exercises in Huon Gulf. She returned to Manus to replenish her supplies, then sailed on 31 December for the island of Luzon in company with TG 79.3.
The transport reached Lingayen Gulf on 9 January 1945. After unloading her troops and cargo, she left the area on the 11th. The transport arrived at Leyte on 15 January, where she took on elements of the 38th Infantry Division. On 26 January, Alpine got underway back toward Luzon. Following two days of amphibious training exercises, the transport anchored off Luzon on 29 January and began lowering her boats at 0615. The next day, she finished this landing and retired to Leyte. Alpine spent the next month providing logistical support to smaller craft present in San Pedro Bay. She also underwent a period of tender availability.
Alpine's next assignment was to support the invasion of Okinawa and Nansei Shoto. She loaded Army troops and got underway on 12 March to conduct a week of landing exercises off the southern coast of Samar. On 27 March, she sailed with TG 51.13 for Okinawa. On 1 April, Alpine began lowering her boats. At 1908, a Japanese plane approached Alpine from the port quarter. At 1910, she took a bomb hit on the starboard side of her main deck. The plane itself then hit the ship, causing fires in the number 2 and 3 holds. By 2200, the transport was listing seven degrees to port. Another ship came alongside and assisted Alpine's firefighting efforts, and, by 2300, the fires were under control. The crew then began their search for casualties and discovered that 16 men had been killed, and 19 were injured.
On 2 April, USS Gear came alongside to assist the ship's force in making repairs.
Alpine left Okinawa on the 6th, bound for the United States via Saipan and Pearl Harbor. She reached the naval station at Seattle, Washington, on 30 April and entered drydock on 1 May for overhaul and repairs. Her patching was completed by 29 June, and Alpine got underway on 5 July for three weeks of refresher training off the west coast. From 21 to 25 July, Alpine loaded supplies and personnel at Oakland, California, for shipment to Okinawa. En route, she stopped at Pearl Harbor on 31 July and Eniwetok on 9 August. While steaming to Ulithi on 15 August, Alpine received the announcement that hostilities had ended. She reached Ulithi on 18 August and remained there through 3 September awaiting orders.

After brief stops at Taku, Weihaiwei, and Qingdao, China, Alpine set out for the long journey back to the West Coast. The transport reached San Diego on 19 November, then underwent a fortnight of voyage repairs. On 5 December, she returned to the western Pacific. Alpine steamed to Nagoya, Japan, arriving on 26 December. There, she embarked 1,915 Army troops, reversed her course, and steamed back to the United States. She arrived at Tacoma, Washington, on 14 January 1946 and, 12 days later, began a voyage, via the Panama Canal, to Norfolk, Virginia.
