On 18 February 1951, Orleck sailed for her first combat operations. Joining United Nations forces off the east coast of Korea, she remained off that peninsula until June, alternating carrier escort duties (TF-77) with shore bombardment missions (TF-95). Retiring to Okinawa during June, she returned to the combat zone in July and again operated with both TF 77 and TF 95.
Arriving back at San Diego 15 October, she trained destroyer crews and conducted individual and squadron exercises until her next return to the Far East in late June 1952. Arriving at Sasebo on the 26th, she soon joined TF 95 for blockade and logistics interdiction missions. On 15 July, while patrolling to the south of Yang-do Island, she became a charter member of the force's Train Busters Club. Planning and patience had put her in the right position to smash a North Korean supply train as it passed between two tunnels. Duplicating the feat on the 27th she kept up her offensive tactics until reassigned, first to carrier duties with TF 77 and then to TF 72 for Taiwan Strait patrol. She returned to Korea 8 October and during the remaining two months of her tour again alternated between TFs 77 and 95.
After Korea Orleck rotated regularly between duty in WestPac and training exercises off the west coast. In the Far East when the Tachen Islands crisis arose, she patrolled off those islands until relieved just prior to their evacuation in February 1955.
