The success of the initial experimental use of the Multiple Mirror Telescope (MMT) as a coherent phased array at submillimeter wavelengths indicates that the precipitable water vapor over Mt. Hopkins is low enough to permit routine operation at 870-microns, and frequent operation at 350 and 450 microns. A coherent superheterodyne receiver and a novel beam-combiner were used to make spectral line maps of the J = 3-2 line of CO. The combination of large collecting area, high angular resolution, and good atmospheric transmission, render the MMT superior to other telescopes for both continuum and spectral line astronomy at submillimeter wavelengths.
