Public Profile

Ultracor is a designer and manufacturer of specialty core materials and has an extensive space flight heritage. Ultracor is used in spacecraft Antenna Reflectors, Optical Benches, Solar Arrays, and other lightly loaded structures which must be positioned with accuracy and stability in order to properly perform. Its quartz honeycomb serve as a high performance constituent material in the Galileo GPS constellation. Thales Alenia Space originally selected Ultracor quartz honeycomb for the first four Galileo satellites scheduled for launch later in 2010. Germany’s OHB, which won a contract for the next eight satellites, has selected Thales Alenia Space to supply the antennas, thus ratifying the original antenna design using Ultracor quartz honeycomb. Ultracor swas elected by NASA and Textron Defense Systems as the specified honeycomb for development as a constituent material in the Orion heatshield. Textron selected Ultracor to research and develop a material comparable with the honeycomb utilized on the original Apollo heatshield. As time and technologies change, Ultracor engineered and fabricated a material grounded in the heritage of early human spaceflight updated with the high quality production techniques developed by Ultracor during its fifteen year history. Ultracor is proud to be a part of the next generation of American space exploration. In December of 2008, Salt Creek Capital aquired Ultracor. In March, 2014, Gemini investors and managment recapitalized the company marking the exit for Salt Creek Capital
