History of Coast Guard Investigative Service, Detroit

The U.S. Coast Guard Investigative Service (CGIS), as it is known today, came into existence in 1915 by the assignment of a “Chief Intelligence Officer” at Coast Guard Headquarters in Washington, D.C.; it remained relatively unknown to the general public until the enactment of prohibition. From then on “Coast Guard Intelligence” grew in personnel and responsibility. In 1986, Coast Guard Intelligence was split and “Coast Guard Investigations” was formed. In 1996, Coast Guard Investigations was replaced by the present-day “Coast Guard Investigative Service (CGIS).”
