I. MATERIALS TECHNOLOGY: The metallic, ceramic and composite materials are primarily related to structural functions in aircraft, spacecraft, missiles, undersea
vehicles, and propulsion devices. Polymers provide seals and sealants for containment of identified fluids and lubricants for various vehicles and devices. High density graphite is used in missile nosetips, jet vanes and nozzle throats. Selected specialty materials (i.e., stealth and the performance of these materials) provide critical capabilities that exploit electromagnetic absorption, magnetic, or superconductivity characteristics. These technologies are associated with: - Advanced metals and alloys - Non-composite ceramic materials - Ceramic, cermet, organic and carbon materials - Polymeric materials - Synthetics fluids - Hot isostatic - Densifications - Intermetallic - Organometals - Liquid and solid lubricant - Magnetic metals and superconductive conductors J. INFORMATION SECURITY: Technologies associated with cryptography and cryptographic systems to ensure secrecy for communications, video, data and related software. |
