 | The mission of the Electronic Combat Range (ECR) Division is to develop, operate, maintain, and continuously improve a free space laboratory. ECR provides engineering, testing (DT&E / OT&E), analysis, and training resources to developers, integrators, testors, and users of systems that counter or penetrate air defenses. Existing and planned ECR capabilities provide an effective, affordable, and accurate ability to examine installed radiofrequency warning and countermeasures equipment. |

| Almost all US aircraft losses since Vietnam have been to MANPADS(Man Portable Air Defense System). MANPADS are a principal weapon of terrorists. MANPADS are cheap, lethal, available and can obstruct US air superiority. Most military aircraft have inadequate or no Missile Warning Systems. An open-air, closed loop Test and evaluate (T&E) capability to evaluate infrared (IR) warning & countermeasures, quantify end-game effectiveness, and evaluate installed, integrated systems in military aircraft ... |

| A new cyanate ester monomer was prepared from bis(4-cyanatophenyl)-dimethylsilane (SiMCy) and fully characterized by analytical and spectroscopic techniques. The monomer was found to have a melting point about 20 deg C lower than that of the commercial bis(4-cyanatophenyl)dimethylmethane (BADCy) with similar melt viscosity, curing kinetics, and post-cure glass transition temperature. Analysis of the single-crystal molecular structure by x-ray diffraction showed that intermolecular packing was dominated by weak hydrogen-bonding attractions between ... |

| The NAVAIR Weapons Division (NAVAIR WD), China Lake, CA, is the Navy's largest research, development, test, and evaluation (RDT&E) facility. China Lake's mission includes the design, characterization, and qualification of new weapons systems. This RDT&E mission generates sizeable quantities of widely varying energetic wastes. Due to the damaged and/or potentially unstable nature of these wastes, they cannot be transported off-Center and must be treated on- site. The preferred method of ... |

| In Paris around 1890, A. V. L. Verneuil developed a flame fusion process to produce ruby and sapphire. By 1900 there was brisk demand for ruby manufactured by Verneuil's method, which was used with little alteration for 50 years. From 1932-1953, S. K. Popov in the Soviet Union established a capability for manufacturing high quality sapphire by the Verneuil process. In the U.S., under government contract during World War II, ... |

|
| Results are compared for several different sets of 4-point flexure strength measurements on sapphire as a function of crystal orientation and temperature. The only consistent trend is that strength drops rapidly with increasing temperature when the c-axis of the crystal is the principal axis of tension and compression. Using Grafoil between sapphire and the load fixture increases the apparent strength of specimens whose principal axis is c by a factor ... |

|
| From 1989 to 2000, the U,S. Navy sponsored research and exploratory development programs to make optical quality chemical vapor deposited diamond and to learn its properties. This paper recounts the development of optical quality diamond and discusses the properties and fabrication capabilities that were achieved. In the year 2002, there exists a commercial capability for optical quality diamond, but the price keeps it out of the hands of all but ... |
