Improve was laid down 1 June 1943 by Savannah Machine & Foundry Co., Savannah, Georgia; launched 26 September 1943; sponsored by Mrs. J. E. Poythress and commissioned 29 February 1944.
During this period Improve swept coastal waters, occasionally exchanging fire with German shore batteries. The enemy still controlled the Italian coastline in this area, and menaced sweeping operations with one-man torpedoes and other devices. The ship helped sweep a channel into Mentone 9–10 September and assisted sinking a one-man torpedo on the 10th. From October until March 1945 Improve swept mines and performed patrol duties at Bizerte; Cagliari, Sardinia; and Palermo, Sicily. Her group developed the new technique of using a Navy blimp to spot floating mines.
Following a brief operation off Anzio 3 March, Improve resumed operations off Sardinia and Sicily, before departing Oran 17 April for the United States.
Transfer to the Pacific Fleet
USS Improve arrived Norfolk, Virginia, 5 May 1945 and, with the focus of war now shifted to the Pacific, sailed 5 July for duty in that theater. She proceeded via the Panama Canal to San Pedro, Los Angeles, arriving 26 July, and remained there on training duty until after the end of the Pacific war. The need for minesweeping operations was still great, however, and Improve sailed 17 September for Pearl Harbor, Eniwetok, Saipan, and Okinawa. She arrived off Sasebo 17 November for additional minesweeping duty and finished the year working off Formosa and in the Pescadores.
Decommissioning
In March 1946 the ship was at Shanghai, earmarked for transfer to China, but she was subsequently returned to Seattle, Washington, and decommissioned 6 November 1946. Improve was eventually turned over to the Maritime Commission and sold 24 February 1949 to Ricardo Granja and renamed MV Ecuador. She was sunk in 1953.
