Shawnee was a composite-construction tug that was built by the Union Construction Company in Oakland California. She was launched at 11:30 a.m. on 15 November 1921 and christened by her sponsor, a "Mrs. Dunham." Shawnee was accepted by the Coast Guard and commissioned on 8 March 1922. As completed, she had a tall, slender stack, a heavy mainmast, and a lighter foremast forward of the bridge structure.
She was stationed at San Francisco, California, with cruising grounds from Cape Blanco, Oregon down to the Mexican border. She carried out search and rescue, towing, customs boardings, transportation of officials, and law enforcement duties as needed. She transferred to Eureka, California after 1935. She underwent conversion and repair in the summer of 1942 which included the addition of new armament that included two 20mm/80, single-barreled anti-aircraft cannons and four "single thrower projectors" had her depth charge tracks removed. She also had a permanent degaussing system installed. She remained based out of Eureka through the end of World War II.
She was decommissioned on 21 November 1946 and sold a year later to the Oakland Manufacturing Company.
