She steamed into Vũng Tàu harbor on 15 February and reported for duty with River Assault Flotilla (RivFlot) 1. "Askari" spent the remainder of her navy career providing repair and other support services for the river monitors, motorboats, and amphibious craft attached to Allied riverine forces in the Mekong Delta. She stayed at Vung Tau until the second week in June, when she moved into the delta proper. The repair ship arrived at Nhà Bè on the Soài Rạp river about south of Saigon on 13 June. The mobility of the riverine forces was greatly enhanced by the fact that their base consisted of ships like "Askari" that could move with them throughout the delta and be close at hand to provide support services. A permanent base ashore would not have afforded such immediacy.
