The privateer was a World War II and Korean War era patrol bomber of the U.S. Navy derived from the Consolidated B-24 Liberator. In addition to other types of missions, privateers were used by the US Navy for signals intelligence (SIGINT) flights off of the coast of the Soviet Union and the People's Republic of China.
