a bearing and the estimated time until arrival from a point ashore. This was converted to a bearing and time to arrival at Shelter and relayed from Shelter to the other ships in the battle group. On 19 March 1945, Shelter departed Ulithi with Mine Group 2 for exploratory sweeps in the Kerama Retto area, and the western side of Okinawa, from 26 March until the initial invasion landings on 1 April. Division 36 also, on D-Day minus one, destroyed mines at the landing site with gunfire, being too shallow to sweep. She made assault sweeps at Ie Shima on 8 and 14 April, served on antisubmarine patrol, and departed on 4 May for Ulithi, thence to San Pedro Bay, Leyte, Philippine Islands. Lieutenant Lancaster then assumed command. Here, she joined a convoy which reached Okinawa on the 29th. The following three weeks were largely taken up with sweeping of minefields off Myako Jima in the East China Sea. She stood out of Kerama Retto on 8 July 1945 as escort unit for LST Group 45 which entered San Pedro Bay on 13 July, and departed Leyte Gulf on 19 August with a convoy that reached Okinawa on the 24th. Six days later, she sailed with a minesweeping task unit that swept the Arcadia minefields in the Yellow Sea in preparation for the landing of occupation forces on the Korean peninsula by the Ninth Fleet on 7 September 1945. She then proceeded to the western coast of Kyushu, Japan, for minesweeping in approaches to Nagasaki and Sasebo, where Lieutenant Douglas Giddings assumed command, clearing 22 moored mines and obstructions from 9 to 16 September 1945. Shelter departed Nagasaki on 26 September 1945 for repairs at Sasebo, then spent 11 to 17 October sweeping 83 Japanese mines in the Tsushima Strait. She repeated this operation 1 to 12 November, sweeping 69 more mines; then became reference ship for a unit of three Japanese Coastal Defense ships sweeping shallow mines line southeast of Tsushima until 16 November 1945. She joined Mine Squadron Twelve on 27 November acting as reference ship until completion of sweeping operations in Tsushima Strait on 4 December 1945. She departed Wakayama, Japan, for home on 11 December touching Eniwetok, Pearl Harbor, and San Diego, where LT JG Samuel F. Melcher Jr assumed command on her way to Galveston, Texas, arriving on 3 February 1946. She shifted to Orange,
