SAN DIEGO, Feb. 22, 2017 (GLOBE NEWSWIRE) -- Kratos Defense & Security Solutions, Inc. (NASDAQ:KTOS), a leading National Security Solutions provider, announced today that Kratos' Defense & Rocket Support Services (DRSS) Division successfully supported the Missile Defense Agency (MDA) and Sailors aboard the USS JOHN PAUL JONES (DDG-53) as they completed the first intercept test of the SM-3 Blk IIA missile on February 3, 2017. The successful SM-3 Blk IIA missile test, designated SFTM-01, was conducted against an advanced Medium Range Ballistic Missile (MRBM) target, developed by Kratos and its Government and industry partners. The Kratos MRBM target was launched from the Pacific Missile Range Facility in Kauai, Hawaii before it was acquired and tracked by the USS JOHN PAUL JONES using its onboard AN/SPY-1D(V) radar and Aegis weapon system. All data indicates that the Kratos MRBM target performed nominally through all phases of flight. The launch of the SM-3 Blk IIA was the first intercept test for the missile developed under a cooperative U.S. – Japanese program. The new interceptor missile features upgraded propulsion systems and an enhanced kinetic warhead aimed at engaging more capable threats over larger areas. The missile will continue to be evaluated for future use aboard ships and ashore as part of Phase 3 of the European Phased Adaptive Approach. The successful three stage separating MRBM target featured Kratos’ Oriole solid propellant rocket motor mounted atop two tandem U.S. Government surplus Mk-70 Terrier kick stages. In addition, Kratos designed and produced payload hardware for the target including mechanical support structures, stabilizing fins, electrical event initiation systems, and active staging and separation systems. Kratos personnel participated in mission planning, payload assembly, testing, and target vehicle build-up and launch operations in support of the successful mission. DRSS is a leading provider of products, solutions, and services supporting ballistic missile defense, hypersonic, Aegis, sounding rocket, directed energy, electromagnetic railgun and other national security and scientific programs.

The challenges of packaging SiC-based electronics for high-temperature applications include their high operating temperatures, wide thermal cycle ranges, and, sometimes, high currents and high voltages. As a result, the selection of metallurgy for high-temperature SiC die attach is crucial to a successful package design, which involves chip metallization, substrate metallization, and die attach alloy. This paper examines off-eutectic Au-Sn as the die attach alloy with a PtAu thick film metallization on AlN substrates. A pure Au thick film layer was printed over the PtAu thick film layer. AlN substrates metalized with refractory MoMn and electroplated Ni/Au were also used. Two different die attach approaches have been investigated, using Sn-Au-Sn off-eutectic thick foil and limited-volume eutectic AuSn (80/20 wt.%) preform. The SiC backside metallizations evaluated were Ti/TaSi2/Pt/Au and Cr/NiCr/Au. Die shear tests were performed after aging at 500°C and after thermal cycling. The shear test results and failure surface analysis are discussed. © 2011-2012 IEEE.

The U.S. Department of Defense said that the Boeing-managed missile defense system for the country had a successful intercept test, which is its first since 2008 The defense system, named the Ground-based Midcourse Defense system, was able to intercept a simulated hostile missile above the Pacific. The GMD system uses the Raytheon Exoatmospheric Kill Vehicle Capability Enhancement II, or EKV CE-II, which detaches from the accompanying rocket to hit the incoming missile. "This is a very important step in our continuing efforts to improve and increase the reliability of our homeland ballistic missile defense system," said Vice Admiral James Syring, Missile Defense Agency (MDA) Director. In the test, a ground-based interceptor missile was launched from the Vandenberg Air Force Base in California. The interceptor successfully neutralized a simulation target, built by Lockheed Martin Corp., that was launched from the Reagan Test Site of the U.S. Army on Kwajalein Atoll in the Republic of the Marshall Islands. According to Lockheed, the simulation target was 14 meters long and was developed to mimic the abilities of ground-launched missiles that can go as far as 5,000 km. The Raytheon kill vehicle successfully intercepted the target, which was the first time that it was able to do so after to failed tests held in 2010. The GMD system failed in five out of its previous eight tests since 2004, when the system's deployment was rushed by the Bush administration amid increasing threats from North Korea. The successful test validated the troubled GMD system, which was launched a decade ago and has cost the government around $40 billion. Earlier in June, Syring said one more failure in testing would have pushed the Pentagon to rethink its motion for an additional 14 interceptors to the current 30 that are located in ground silos in California and Alaska. Ten interceptors have the kill vehicle that was used in the successful test, while the rest of the interceptors still have the kill vehicle that was unsuccessful in a test last year. Syring said that the interceptors will all have the successful kill vehicles installed by the end of the year. Missile Defense Advocacy Alliance founder Riki Ellison lauded the success in the test as a major milestone for the program, saying that U.S. commanders would then need to launch fewer interceptors to counter an incoming warhead. Critics, however, are still not impressed with the Raytheon kill vehicle, pointing to its track record of succeeding only once out of three tries and urging Congress to reconsider the plan to purchase 14 more interceptors.

This paper presents the results from a laboratory study in which hot-mix asphalt (HMA) mixtures with No. 4 sieve screened reclaimed asphalt pavement (RAP) were characterized for their cracking resistance through laboratory performance testing. A typical surface mixture commonly used in the state of Tennessee was evaluated at 0, 10, 20, and 30% RAP contents. Two types of aggregate (limestone and gravel) and three types of asphalt binders (PG 64-22, PG 70-22, and PG 76-22) were used in this study. Mixture cracking resistance was evaluated through Superpave indirect tension (IDT), beam fatigue, and semicircular bending (SCB) tests. The results from this study indicated that the inclusion of RAP generally increased stiffness and indirect tensile strength; however, it generally compromised cracking resistance for the mixtures studied. Mixture properties changed significantly at 30% RAP content as compared to those with 10 and 20% RAP. Field projects validated the findings from the laboratory study. © 2011 American Society of Civil Engineers.

Parametric cost models can be used by designers and project managers to perform relative cost comparisons between major architectural cost drivers and allow high-level design trades; enable cost-benefit analysis for technology development investment; and, provide a basis for estimating total project cost between related concepts. This paper hypothesizes a single model, based on published models and engineering intuition, for both ground and space telescopes: OTA Cost ∼ (X) D (1.75 ± 0.05) λ (-0.5 ± 0.25) T-0.25 e (-0.04) Y Specific findings include: space telescopes cost 50X to 100X more ground telescopes; diameter is the most important CER; cost is reduced by approximately 50% every 20 years (presumably because of technology advance and process improvements); and, for space telescopes, cost associated with wavelength performance is balanced by cost associated with operating temperature. Finally, duplication only reduces cost for the manufacture of identical systems (i.e. multiple aperture sparse arrays or interferometers). And, while duplication does reduce the cost of manufacturing the mirrors of segmented primary mirror, this cost savings does not appear to manifest itself in the final primary mirror assembly (presumably because the structure for a segmented mirror is more complicated than for a monolithic mirror). © 2016 SPIE.

Susan K. Land shares her leadership experiences and the role of women in the field of computer science. According to her, women and girls who have an aptitude for science must be encouraged that it is a career where they will be in high demand and never lack for opportunities. The message should be that technology careers allow individuals, regardless of gender, to express their intellect and allow for them to be evaluated on their performance. It should be emphasized that jobs in technical fields are in high demand and will provide for lifelong learning, excitement, and satisfaction and that these jobs never become routine or boring. Sharing her experience, she says that it was during this job that she found the IEEE Computer Society and their package of software and systems engineering standards. These standards provided her with accepted guidance to support team training in the basics such as requirements management, configuration management, and quality assurance.

Silicon-on-insulator (SOI) integrated circuits have been demonstrated for use at temperatures up to 300 C. However, to build functional electronics, multiple devices must be interconnected to provide the desired functionality. A system-in-package approach has been developed using thick-film technology on Si3 N4 ceramic substrates. Si3 N4 has a near coefficient-of-thermal-expansion match to Si and a higher flexural modulus than Al2 O3, which is commonly used for thick-film applications. The conductor metallization is Au. For 300 °C operation, eutectic AuGe die attach was used with a Ti/Ti:W/Au backside die metallization. After 3000 h at 325 C, the mean die shear strength decreased from 3.96 to 3.33 kg mm2, a decrease of only 16%. Formation of AuSiGe ternary eutectic (melting point 326 Cdeg; was observed and limits the use of AuGe die attach to 300 C°. SOI dies typically have Al wire bond pads that are not compatible with Au thermosonic wire bonding for high-temperature applications. Two plating processes have been examined: electroless Ni/immersion Au/electroless Au and electroless Ni/electroless Pd/immersion Au. The plating processes provide a barrier layer (Ni) and a wire-bondable finish (Au or PdAu) over the Al wire bond pads. After 10000 h at 300 C°, the wire pull force for the Ni/Au samples decreased by ∼30% due to annealing of the Au wire, while the ball shear force increased by ∼ 35%. The daisy-chain electrical resistance remained relatively constant. For the NiPdAu samples, after 2000 h at 320 C°, the ball shear force remained constant or increased slightly, the wire pull force decreased by ∼25% due to annealing of the Au wire, and the daisy-chain resistance remained relatively constant. After 3000 h, however, cratering of the Si wire bond pad was observed corresponding to some first bond pad lifts and increased daisy-chain resistance. Optimization of the wire-bonding parameters for bonding to the harder Ni/Pd/Au bond pad is required to eliminate cratering. © 2006 IEEE.

Improved techniques to develop future System of Systems solution architectures are a systems engineering imperative. The systems engineer must be able to produce quantitative Measures of Performance that parse good performing architectures from bad architectures in a very complex and dynamic domain often and early during concept development. This paper proposes innovative System of Systems Engineering techniques to manage risks and reduce costs in complex systems. We suggest a combination of graph theory, Big Data and Uncertainty Quantification are foundational tools that can model architectures and more importantly the movement of data across architecture interfaces. This provides a mathematical foundation for quantitative architecture, model based systems engineering and simulation environments enabling continuous prototype testing in a model environment. The result is a means to quantitatively validate viable complex architectures early in the lifecycle. This paper describes a graph-based approach to model complex architectures. Complexity will be defined mathematically as a function of the number of entities, inter-entity relationships and active event sequences in the graphical architecture. Uncertainty quantification compares the graph model to the physical System of Systems based on quantities of interest. Big Data facilitates analytics across continuous data threads in the architecture. © 2014 The Authors. Published by Elsevier B.V.
