Orleck (DD-886) was laid down 28 November 1944 by Consolidated Steel Corporation of Texas, Orange, Tex., named Orleck 11 January 1945; launched 12 May 1945, sponsored by Mrs. Joseph Orleck, widow of Lt. Orleck; and commissioned 15 September 1945 Comdr. J. D. Andrew in command.
Following a Caribbean shakedown, Orleck got underway 20 January 1946, for San Diego whence she steamed west, in mid-March, to join the 7th Fleet. Between 20 April and 15 August she conducted mail runs from Hong Kong to Shanghai, Tsingtao, and Taku, China, and Jinsen, Korea and also assisted in minesweeping operations in Hainan Strait. A month of exercises off Guam preceded her joining TF 77 for new operations off China and Japan.
Sailing home in January 1947, she remained on the West Coast until departing for the western Pacific in February 1948. At Eniwetok during March, she participated in Atomic Energy Commission experiments. From Eniwetok, she continued west, reporting to COMNAVFE 5 April. On completing her second WestPac tour she turned northeast for cold weather operations off Alaska from January to March 1949. Operations off the west coast and Hawaii ended in October as the destroyer again sailed west for her annual overseas deployment.
