(U) A. Mission Description and Budget Item Justification: This Applied Research program is the primary source of advanced materials and processes to reduce life cycle costs and improve performance, affordability, supportability, reliability, and survivability of current and future Air Force systems. Structural, propulsion, and sub-systems materials and processes are developed for aircraft, missile, space, satellite, and launch systems applications. Electronic and optical, advanced electromagnetic, and laser protection materials and processes are developed for application in Air Force aircraft, missile, space, and personnel protection systems. Advanced nondestructive materials evaluation methods, materials design data, pollution prevention materials, materials failure analysis, and materials repair methods are developed to improve the sustainment of Air Force systems for the current and future warfighters. Note: In FY 1997, Congress added $7.5 million and $1 million for composite materials research and advanced paint systems, respectively, which explains the perceived decrease in FY 1998. In FYs 1999 and out, additional emphasis has been placed on improved materials, space systems, and aging aircraft.

(U) A. Mission Description and Budget Item Justification: Develops materials technologies for optical and electro-optical devices and subsystems for aircraft, missile, and space systems. This project also develops new materials for protection of aircrews, sensors, aircraft, and space systems from laser threats. Radar modules, microwave devices, infrared (IR) detectors, photonics, and optical processors are used in target detection, data processing, electronic warfare, and communications. The performance of these systems is constrained by the quality and physical characteristics of these materials. New materials are developed that improve the production quality and rates to develop advanced electronic and optical materials that offer higher operating speeds, greater bandwidth density, improved thermal management, greater sensitivity, and expanded dynamic range. Protection from lasers is dependent upon the power level and wavelength or color emanating from the laser device and the susceptibility of the material or system being lased. Additionally, protection schemes are dependent on other characteristics of the laser such as variability of the wavelength and mode of operation (continuous wave or pulsed). Materials are optimized to counter the most prominent threat wavelengths and new materials are developed to respond to emerging threat wavelengths and ultimately to reject laser energy independent of threat wavelengths.
