The general design and performance characteristics of a 1-m diameter f/1.4 normal incidence X-ray Multilayer Telescope (XMT) operating at 0.13 keV are described. The principal scientific objectives of the XMT include soft diffuse X-rays, stellar surveys, interstellar dust grains, and soft excess in AGN. The feasibility of meeting these objectives using an XMT telescope is assessed.
