Nokomis, a 218-ton harbor tug, was built at the Puget Sound Navy Yard, Washington. Placed in service in March 1940, she was assigned to the Fourteenth Naval District for service at Pearl Harbor. Reclassified YTB-142 in May 1944 and YTM-142 in February 1962, Nokomis operated in the Pearl Harbor area into the early 1970s. She was stricken from the Naval Vessel Register in May 1973 and sold in April 1975.
