    Dictionary of American Naval Fighting Ships: Soon after the United States entered World War I, Satellite, a wooden yacht, built during 1887 by John F. Mumm at Brooklyn, N.Y., was enrolled in the Naval Coast Defense Reserve for Navy service. She was delivered to the Navy on 9 July 1917 by her owner, E. L. Sanborn of New York, and commissioned on 7 September 1917, BMC Thomas E. Roberts
    in command.

    Assigned to local duty within the 7th Naval District, Satellite was based at Key West, Fla., during her World War I service. She trained crews of new submarine chasers about to be commissioned, by a vigorous schedule of seamanship drills and gunnery exercises, until inactivated about 6 April 1918 for overhaul. Not returned to full service because of boiler trouble, Satellite was struck from the Navy list on 30 March 1920 and subsequently sold for scrapping.
