History: USCGC Duane was launched on June 3, 1936 as a search and rescue and law enforcement vessel. As the cutters are named for former Secretaries of the Treasury Department, the cutter Duane was named for William John Duane, who served as the third Secretary of the Treasury to serve under President Andrew Jackson. Participating in WWII and Vietnam, Duane was decommissioned in 1985 as the oldest active military vessel. Duane rested in Boston until it was towed to Key Largo, along with its sister ship Bibb, and was sunk November 27, 1987. On May 16, 2002, the cutter Duane  was added to the U.S. National Register of Historic Places.
