USCGC Courier (WAGR-410)
From Wikipedia, the free encyclopedia
USCGC Courier (WAGR/WAT-410) was a cutter in the United States Coast Guard.
Originally launched in 1945 as the M/V Coastal Messenger, the United States Coast Guard Cutter Courier was a joint operation between the United States State Department and the United States Coast Guard. For twelve years during the 1950's and 1960's, she served as a portion of the Voice of America radio network during the Cold War, at a time when the Soviet Union had attempted to jam portions of the network. Courier contained the most powerful communications radio transmitter ever installed onboard a ship, a RCA 150-kilowatt medium wave transmitter, as well as two 35-kilowatt short-wave transmitters. She also held the record for longest deployment overseas - from 17 July 1952 to 13 August 1964, she spent no time in United States territorial waters.
She was decommisioned upon her return to Yorktown, Virginia, and later used as a training vessel from 1966 to 1972.
