The USRC Andrew Johnson was a wooden-hulled side-wheel steam cutter constructed as part of the Chase Class, built between 1865 and 1866 for the United States Revenue Cutter Service. These cutters, including the Johnson, were designed primarily for operations on the Great Lakes, featuring iron diagonal bracing in their hulls to enhance strength and durability. Powered by walking-beam steam engines, the Johnson exemplified the maritime technology of the period, combining wood construction with steam propulsion. Commissioned on May 1, 1865, the Johnson served primarily out of Milwaukee, Wisconsin, maintaining a dedicated presence on the Great Lakes. During the navigation season, she patrolled the lakes, enforcing maritime laws and supporting revenue collection, while during the winter months, typically from late November to May, she was laid up and out of active service. Her operational role was vital in maintaining security and order on the inland waters during her active years. In 1879, the vessel underwent a significant rebuild at Manitowoc, Wisconsin, during which her beam was increased by two feet. This modification likely improved her stability and seaworthiness, reflecting ongoing efforts to maintain her effectiveness. After nearly three decades of service, the Johnson was placed out of service and sold in May 1897 to Charles E. Benham for $2,250. Subsequently, she was acquired by the Ohio Naval Militia, the precursor to the Naval Reserve, and was repurposed for training missions. Overall, the USRC Andrew Johnson holds maritime significance as part of the early fleet of the Revenue Cutter Service, representing the transition to steam-powered cutters designed for inland and Great Lakes operations. Her service history exemplifies the vital role these vessels played in maritime law enforcement, safety, and training during the late 19th century.
