The Air Force is interested in high stiffness, lightweight technologies for beam control of tactical airborne and relay mirror high-energy laser systems. The corrected system wavefront error can be minimized using low figure error/surface finish, low print-through, high-stiffness, Silicon Lightweight Mirror Systems (SLMS ) technology with high-reflectivity, very low absorption (VLA) coatings. Some specific organizations and missions within the Department of Defense requiring high-performance lightweight mirror technology include MDA/AL/MP/AS and ABL, ARMS, ATL, EKV, and STSS. In Phase II we will demonstrate the scalability of SLMS technology by producing a bonded, high-stiffness, 50 cm aperture F/1.25 on-axis parabolic SLMS with dual-band coatings (1.06 micron and 1.315 micron) and a targeted areal density of
