Abstract The U.S. Navy is building for the department of Defense and the scientific community, a 600-f t radio telescope at Sugar Grove, West Virginia. When completed in 1962, it will be a significant new tool for astronomical observations at meter and decimeter wavelengths. The radio optics of the instrument will consist of a 600-ft-diam parabolic mirror with a prime focus observing station 240 ft above the surface. The geometry of the optics is maintained through changing environments by a multiplicity of closed loop servo mechanisms which continually refigure the mirror and adjust the focus. The radio optics of the telescope are mounted in an altitude-azimuth configuration providing access to the entire sky. Tracking rates are sufficient to follow celestial objects at distances beyond one earth radius. The 2.6X 10~ m1 collecting area of the telescope, effective at wavelengths of low absorption, will provide promising approaches to intergalactic studies as well as more problems. In addition to the classical technique of passive observation, the new field of radar astronomy will be provided with a versatile and powerful tool.
