After shakedown, Knudson departed Norfolk, Virginia on 18 January 1945 for World War II service in the Pacific. Steaming via San Diego, California, she arrived at Pearl Harbor, Territory of Hawaii, on 9 February 1945 for training with underwater demolition team units. With Underwater Demolition Team 19 embarked, she departed Pearl Harbor on 28 February 1945, stopped at Eniwetok, and arrived at Ulithi Atoll on 12 March 1945 to prepare for operations in the Ryukyu Islands.

While serving as antisubmarine screen on 26 March 1945, she was attacked by a Japanese bomber. Her guns shot the plane down after two bombs had missed her close aboard.

On 1 April 1945, the day that the initial amphibious landings on Okinawa took place, Knudson continued antisubmarine warfare patrols during amphibious landings at Hagushi, Okinawa. During the next two weeks she conducted screening patrols off the western shores of Okinawa in support of the Okinawa campaign.

Knudson departed Okinawan waters on 14 April 1945, escorting the battleship USS Nevada (BB-36) to Guam, arriving there on 19 April 1945.

Knudson embarked Underwater Demolition Team 25 on 13 August 1945. World War II ended with the surrender of Japan the next day, 14 August 1945, which was 15 August 1945 across the International Date Line in East Asia.

Knudson departed San Diego on 16 August 1945 for the Far East, and arrived in Tokyo Bay, Japan, on 4 September 1945. She operated out of Yokosuka, Japan, until 20 September 1945, when she returned to the United States, arriving at San Diego on 11 October 1945.

Knudson continued her service in the Pacific from 30 October 1945 to 12 May 1946, carrying men and supplies to bases in the Marshall Islands, Mariana Islands, Admiralty Islands, and Philippines.

Knudson recommissioned on 6 August 1953 with Lieutenant Commander J. F. Roohan, Jr., in command. After shakedown and conversion to a high-speed transport flagship, she departed San Diego on 3 May 1954 for the Western Pacific. Arriving at Yokosuka, Japan, on 23 May 1954, she conducted amphibious exercises off Japan, South Korea, and Okinawa.

Clearing Tokyo Bay on 13 August 1954, she set course for the Vietnamese coast, where she arrived at Haiphong, North Vietnam, on 22 August 1954. As flagship for the Commander, Embarkation Group, she participated in Operation Passage to Freedom, through which the U.S. Navy evacuated almost 300,000 Vietnamese from North Vietnam to South Vietnam. From 22 August 1954 to 19 September 1954, she operated out of Haiphong during the loading of refugees, cargo, and military equipment by U.S. Navy ships. Then she steamed to Saigon, South Vietnam, arriving on 22 September 1954.

Continuing to Subic Bay in the Philippines on 2 October 1954, she stopped at Hong Kong before returning to Yokosuka on 1 November 1954. On 7 November 1954 she departed Yokosuka for the United States, arriving at San Diego on 23 November 1954.

Knudson operated out of San Diego and Long Beach, California, supporting amphibious training during 1955 and early 1956.

Departing Long Beach on 24 March 1956, Knudson steamed via Pearl Harbor to Eniwetok, where she arrived on 10 April 1956. She supported nuclear tests in the Marshall Islands before returning to Pearl Harbor on 23 July 1956.
