The USS Firm (AM-444/MSO-444) was an Aggressive-class minesweeper constructed for the United States Navy. Launched on April 15, 1953, by J. M. Martinac Shipbuilding Corporation in Tacoma, Washington, the vessel was sponsored by Mrs. Joseph S. Martinac. She was officially commissioned on October 12, 1954, and reclassified as an MSO-444 (Mine Sweeper, Ocean) on February 7, 1955. Designed as a minesweeper, the USS Firm featured the typical characteristics of her class, optimized for mine clearance operations. Her operational history began with her home port in Long Beach, California, serving as the headquarters for Mine Force, Pacific Fleet. She primarily conducted training exercises along the West Coast, but her role expanded when she was converted to serve as a flagship for Mine Division 94 in 1955. Throughout her service, USS Firm undertook multiple deployments, including significant periods in the Far East. Between 1956 and 1959, she served with the 7th Fleet, participating in exercises with the navies of Korea, China, and Thailand, and visiting numerous ports across Asia. She continued West Coast operations through 1962. Starting in April 1965, USS Firm was assigned to Operation Market Time, a mission aimed at interdicting Communist arms and contraband during the Vietnam War. As part of Mine Divisions 72, MD-91, and MD-33, she frequently served as a flagship and completed five deployments to Vietnam until 1971. Her efforts earned her several awards, including the Vietnam Service Medal, Vietnam Campaign Medal, two Navy Meritorious Unit Commendations, and the Vietnam Cross of Gallantry. The vessel was decommissioned on July 5, 1972, and transferred to the Philippines, where she was renamed BRP Davao del Sur (PM-92). She was returned to U.S. custody in 1977, struck from the Naval Vessel Register, and sold for scrapping to Ming Hing and Co., in Hong Kong on July 8, 1977.
