Assigned the task of establishing river patrol units in the Mekong Delta, Belle Grove steamed for Chu Lai, South Vietnam, on 10 January 1966. Arriving in that port on 5 February, the ship spent the next two months maintaining LCM landing craft, PBR river patrol boats, and UH-1B "Huey" helicopters in the Rung Sat Special Zone. She also served as a command center that coordinated Navy riverine patrols and Army helicopter sweeps against Viet Cong forces as part of Operation "Jackstay." Those attacks, carried out in conjunction with B-52 strikes, lasted from 26 March to 4 April. In mid-April, she coordinated the first PBR and helicopter patrols on the Long Tau river. On 19 April, Tortuga (LSD-26), relieved her as armed-helo support ship at Vung Tau, and Belle Grove steamed for the Philippines that same day. After delivering cargo to Subic Bay the ship returned home, via Yokosuka and Pearl Harbor, on 28 May.
