A number of YMSs were transferred to other navies during or after the war. During Project Hula, the United States secretly transferred 31 of them to the Soviet Union between 17 May and 3 September 1945, and some of these saw action in the Soviet Navy during Soviet military operations against the Japanese between 9 August and 5 September 1945. The transfer of five more was canceled when transfers halted on 5 September 1945. One, "T-610" (ex-), sank in 1945 while in Soviet service, and the Soviet Union transferred two, "T-605" (ex-) and "T-611" (ex-), to the People's Republic of China after striking them from the Soviet Navy list in 1955; during 1955 and 1956 the other 28 were scrapped by the Soviet Union or destroyed off its coast by mutual agreement between the two countries. Five YMSs served in the German Navy in different functions for tests, trials, and training; all of them had a civilian crew and were decommissioned between 1975 and 1988.
