Alpine (APA-92) was launched 10 July 1943 by Western Pipe and Steel Co., San Francisco, Calif., for the Maritime Commission, as Sea Arrow; sponsored by Mrs. Helen Marsh, transferred to the Navy 30 September 1943; and commissioned 22 April 1944, Lieutenant Commander G.K.G. Reilly in command.
Alpine joined the Pacific Fleet and during 21-27 July 1944 took part in the invasion of Guam. She returned to Pearl Harbor before steaming westward to participate in the Leyte landings (20 October). After loading reinforcements at Hollandia, Alpine returned to Leyte 18 November. Scarcely had the transport arrived off Leyte when she was hit by a Japanese suicide plane which demolished one small landing craft, killing its three-man crew, and tore a hole in the port side. Alpine completed unloading and retired to Manus, Admiralty Islands, for repairs. Repairs were completed in time for Alpine to take part in the Lingayen landings (11 January 1945) and the landings around Subic Bay, Luzon (29-30 January). She spent the next two months as temporary repair ship for the small landing craft at Leyte.
In March 1945 Alpine departed Leyte for the Okinawa landings (1 April) At 1910 on 1 April, before she could land all her troops, Alpine was hit again by a Japanese suicide plane. The plane crashed through the forward deck setting fire to numbers two, three, and four holds. Alpine had 21 of her passengers killed, 18 of her passengers and 8 of her crew wounded. She completed temporary repairs at Okinawa, 7 April, and then steamed to Seattle, Wash., for permanent repairs, arriving 30 May.
