Illusive (AM-448) was launched by Martinolich Ship building Co., San Diego, Calif., 12 July 1952; sponsored by Mrs. Vito Marino; and commissioned 14 November 1953, Lt. Comdr. J. E. Ruzic in command.

After shakedown and individual ship training out of Long Beach during 1954, the ship entered Long Beach shipyard for extensive modifications October 1954 to February 1953. She was reclassified MSO-448 7 February 1955. She continued to operate out of Long Beach, taking part in a major Pacific Fleet training exercise in November 1955. For the next year she trained in California waters.

Illusive again entered the yard in November 1956, this time to replace her engines with experimental Packard models, and until May 1957 was engaged in engineering evaluation trials. She then sailed for her first deployment to the Far East 1 August 1957. Through December she took part in the vital operations of the 7th Fleet for the maintenance of peace and security in East Asia. She took part in joint exercises with Japanese naval units 6-9 October and with the Chinese Nationalist Navy 15 to 17 December 1957. Illusive returned to Long Beach 15 February 1958.

The remainder of 1958 was spent in training operations out of Long Beach. In 1959 she remained in California waters, and took part in a large amphibious exercise off Camp Pendleton. Illusive then made-ready for her second deployment to the western Pacific, sailing 8 January 1960 for Japan. During this critical period, in which American Navy ships were increasingly active in helping to prevent Communist takeover of the countries of Southeast Asia, the minesweeper carried out maneuvers off Japan, the Philippines, and Okinawa. Illusive returned to Long Beach 19 July 1960.

The year 1961 saw the ship return to the Far East. She sailed 24 August and operated in the Philippines as well as out of Guam and Formosa. She moved to Sattahib, Thailand, 25 November, as American ships demonstrated support for that nation, and in December visited Bangkok, Thailand, and Saigon, capital of the struggling Republic of South Vietnam. During this period Illusive conducted training exercises with several Southeast Asian navies. She was particularly active in training South Vietnamese officers and men until sailing for Long Beach 3 March 1962.

The veteran ship returned to the far Pacific in August 1963 and after stopping at island bases along the way arrived Sasebo 23 September. In the months that followed Illusive took part in 7th fleet training with Korean, Nationalist Chinese and Japanese minesweepers. She returned to Long Beach 7 March 1964 for yard overhaul, followed by refresher training off the coast of southern California.

On 13 August 1965 Illusive departed Long Beach for training in the Pacific that took her to Hawaii, the Marshalls, the Marianas, and the Philippines. She stood out of Subic Bay 2 October 1965 to join the "Market Time Patrol" vigilantly trying to stop the coastal flow of contraband by junks and boats to Vietcong the full length of Vietnam's 1,000 mile coastline. Her patrol service may include acting as a mother ship for replenishing the needs of "Swift" boats, providing gunfire support to U.S. forces ashore, or conducting a hydrographic survey on shoreline depths, in addition to patrolling thousands of miles within the inspection zone to intercept Vietcong men and supplies. Illusive continued this vital duty until she turned homeward in February 1966. The minesweeper reached Long Beach 28 April. She operated along the West Coast for the remainder of 1966 and into 1967.
