wanted 480 of the 585 combatant ships it had transferred to the Soviet Union for World War II use returned. Deteriorating relations between the two countries as the Cold War broke out led to protracted negotiations over the ships, and by the mid-1950s the U.S. Navy found it too expensive to bring home ships that had become worthless to it anyway. Many ex-American ships were merely administratively "returned" to the United States and instead sold for scrap in the Soviet Union, while the U.S. Navy did not seriously pursue the return of others because it viewed them as no longer worth the cost of recovery.Russell, Richard A., ''Project Hula: Secret Soviet-American Cooperation in the War Against Japan'', Washington, D.C.:

, 1997, , pp. 37-38, 39. The Soviet Union never returned ''Caution'' to the United States, although the U.S. Navy reclassified her as a "fleet minesweeper" (MSF) and redesignated her MSF-158 on 7 February 1955.
