The Submillimeter Telescope (SMT) dedicated to observations in the shortest wavelength submillimeter windows (350 to 450 microns) is described. An overall reflector accuracy of 15 microns is achieved under operational conditions through the use of carbon fiber reinforced plastic in critical sections of the structure. This minimizes thermal effects under varying environmental loads. The 140 m diameter reflector is predicted to have a resolution of 10 arcseconds requiring a pointing and tracking accuracy of better than 1 arcsecond.
