The Defense Department has announced another package of security assistance for Ukraine, which will include additional High Mobility Artillery Rocket Systems (HIMARS), ammunition, and a substantial number of Phoenix Ghost unmanned aerial systems. This latest package includes about $175 million in equipment pulled from existing U.S. military stocks through presidential drawdown authority and $95 million…
The Defense Systems Information Analysis Center (DSIAC) was tasked with determining the extent of energetics additive manufacturing (AM) research and development capabilities in Europe. DSIAC searched available resources for any projects or research being performed by universities or defense organizations in Europe that involve the three-dimensional printing of energetic munitions, explosives, propellants, or rocket engines. There were a few organizations and universities that had…

The Defense Systems Information Analysis Center (DSIAC) is seeking information on technologies, methodologies, and processes that can be used to launch long-rod projectiles at 3 kft/s or greater, resulting in the projectile impacting lengthwise on a target surface perpendicular to the projectile’s line of flight. Of primary interest are methodologies, test procedures and results, and…
The Defense Systems Information Analysis Center (DSIAC) is searching for nonlethal/intermediate force capabilities that can be mounted onto unmanned aerial vehicles and ready for a live, integrated demonstration by the first quarter of calendar year (CY) 2025. These capabilities should weigh up to 150 lb and measure approximately 1 ft × 2 ft. If you…
The Defense Systems Information Analysis Center (DSIAC) is searching for organometallic compounds most often used in depositing tungsten, cobalt, or ruthenium to fabricate low-resistance source/drain contacts in transistor research. Of particular interest are deposition approaches for fin field-effect transistors or gate-all-around transistor designs. If you are willing to assist in this effort or know of…
This webinar focuses on developing methods for manufacturing structural thermoplastic composite materials, characterizing the mechanical properties of such composites, and modeling the static and dynamic performance in relevant military vehicle modeling and simulation (M&S) environments. A thermoplastic polyethylene terephthalate/fiberglass composite was selected for this study due to the high specific strength of e-glass fibers, the…
Researchers have taken many avenues to mitigate how high-energy laser (HEL) weapons affect platform survivability because of size, weight, performance, and cost factors. Protective coatings offer a cheap, lightweight option for counter directed energy weapons (CDEWs) applications. Diffusely reflective coatings can reflect a significant portion of incoming laser energy before it reaches the substrate. The…
Reliability is the probability that an item will perform its intended function for a specified period under stated conditions. It has a significant impact on operating and sustainment costs within the U.S. Department of Defense (DoD), which typically represent 70% of the program’s total life-cycle costs [1].
Modeling and simulation are key for the iterative development of thermal protection systems (TPS’s) for hypersonic weapons. In this work, the temperature-dependent flexural strength (FS) of α-SiC ceramic is predicted given Young’s modulus, Poisson’s ratio, and temperature. An artificial neural network (ANN) surrogate model is created to retain property-performance prediction while increasing computation speed.
