USRC Louis McLane, a 357-ton (burden) iron-hulled side-wheel revenue cutter, was built at Wilmington, Delaware, in 1861 as the commercial steamship Virginia Dare. Purchased by the Navy in October 1861, she was commissioned as USS Delaware and began active service before the end of the year. During 1862, 1863, and into 1864 she mainly served in the North Carolina Sounds, participating in the capture of Roanoke Island in February 1862 as well as in other offensive and blockade enforcement operations, but also operated in Virginia waters in mid-1862 and for some of 1863. In late March 1864 Delaware was transferred permanently to Virginia, and spent the rest of the Civil War on the James River, in the Hampton Roads area and on Chesapeake Bay. Decommissioned in August 1865, she was sold to the Treasury Department soon afterwards.

Commissioned as USRC Delaware, she was sent to the Galveston, Texas, later in 1865. Beginning in 1868 she operated out of Mobile, Alabama. The cutter was renamed Louis McLane in June 1873. The remainder of her career was spent in the Gulf of Mexico, based at Pensacola and Key West. Following over four decades of Navy and Revenue Cutter Cutter service, Louis McLane was sold in October 1903. She subsequently became the civilian steamer Louis Dolive and was employed until about 1919, when she was removed from shipping registers.
