USS Guardian (YAGR-1) was a Guardian-class radar picket ship acquired by the U.S. Navy during World War II. Her task was to act as part of the radar defenses of the United States after the close of World War II.
Built and placed into reserve 
Guardian was launched as Liberty Ship SS James G. Squires 8 May 1945 by J. A. Jones Construction Co., Inc., Panama City, Florida; sponsored by Mrs. Elisa Broome; and delivered 31 May to Waterman Steamship Co. The ship served until 5 October 1945, when she was placed in the National Defense Reserve Fleet, James River, Virginia.
The honor of "being the first" 
The first ocean radar station ship was put up into service by the Navy, Guardian conducted shakedown in Roosevelt Roads, Puerto Rico, and surrounding waters, reporting to Newport, Rhode Island, her home port, 2 June 1955.
Equipped with highly sensitive radar gear to enable her to detect, track, and report any aircraft penetrating the continental United States, Guardian was attached to the Eastern Continental Air Defense Command. She and her sister ships spend 3 or 4 weeks at a time off the U.S. East Coast on radar picket duty, even in the heaviest winter weather in the North Atlantic Ocean.
In addition to radar picket duty, Guardian participated in ASW exercises with both American and Canadian naval units and in local operations out of Newport and Key West, Florida. Her designation was changed to AGR-1 on 28 September 1958.
Guardian was decommissioned, 28 July 1965, and struck from the Naval Vessel Register (date unknown). She was returned to the Maritime Commission for lay up in the National Defense Reserve Fleet. Final disposition: she was scrapped in September 1971 at Bilbao, Spain.
