An instrument consisting of a 0.4-meter diameter f/15 telescope, a concave grating spectrometer, and a micro-channel plate detector has been constructed in order to carry out moderate resolution (about 10 A) spectrophotometry of faint extra-galactic objects in the 1200-1700 A spectral band. In its first flight, aboard a NASA Black Brant VC rocket launched from White Sands Missile Range on 1977 April 16, the instrument obtained an excellent spectrum of the quasi-stellar object 3C 273, the first ultraviolet spectrum of a QSO ever obtained from above the earth's atmosphere. In this paper a brief description of the Faint Object Telescope is presented along with preliminary results from the first flight.
