- Company Profile:
A designation or marking which identifies classified operational keying material, and which indicates that this material requires special consideration with respect to access, storage and handling.
Industry:Military
The degradation of infrared sensor resolution due to high-altitude nuclear bursts. Radiation from these bursts causes fluorescence-emission of light from air molecules. The emitted light lies within the long-wave IR spectrum so the atmosphere below appears to the sensor to glow more brightly than usual.
Industry:Military
A material that can be stimulated to produce laser light. Many materials can be used as lasants; these can be in solid, liquid, or gaseous form (consisting of molecules including excimers or atoms) or in the form of a plasma (consisting of ions and electrons). Lasant materials useful in high energy lasers include carbon dioxide, carbon monoxide, deuterium fluoride, hydrogen fluoride, iodine, xenon chloride, krypton fluoride, and selenium, to mention but a few.
Industry:Military
Electromagnetic radiation of high energy which results from either the release of energy from electrons changing orbits about the nucleus (discrete) or the inelastic collision of charged particles with the electromagnetic field of the nucleus. X-rays have wavelengths shorter than those in the ultraviolet region, e.g., less than 10E-6 cm or 100 Angstroms. Materials at very high temperatures (millions of degrees) emit such radiations; they are then called thermal x-rays. As generally produced by x-ray machines, they are "bremsstrahlung" resulting from the interaction of electron of 1 kiloelectron-volt or more energy with a metallic target. (See Electromagnetic Radiation and Thermal X-Rays.)
Industry:Military
The return of objects, originally launched from earth, into the atmosphere.
Industry:Military
Nuclear-armed, long range mid-course interceptor used in SAFEGUARD/Sentinel systems.
Industry:Military
A space vehicle, such as a Brilliant Pebble, which contains only one intercept vehicle.
Industry:Military
For command-oriented functions, the authorization required to perform command operations.
