DSIAC collects and publishes articles related to our technical focus areas on the web to share with the DoD community.
A US Department of Defense scientific advisory board has called on the Trump administration to rebuild the country’s nuclear weapons infrastructure and modernize its nuclear arsenal. The recommendations, detailed in a December report, include the development of new, low-yield warheads to give the military the option of a limited nuclear strike. The report, written by
The next time Marines hit a Pacific beach, they will have the most advanced attack helicopter in the world at their backs. Eight AH-1Z Vipers began arriving at Marine Corps Air Station Futenma in late November to permanently replace the service”s aging fleet of AH-1W Super Cobras, Marine officials said, and more are on the
In an effort to accelerate progress on the electromagnetic railgun development, BAE Systems announced the acquisition of Ohio-based IAP Research. Prior to the acquisition, IAP Research was a major BAE Systems subcontractor on the U.S. Navy-led development of an electromagnetic (EM) railgun. The Dayton team, which is part of BAE’s weapons systems business, has more
A new engine concept from NASA’s Glenn Research Center allows for truly distributed propulsion. The concept enables airframe and system modularity by allowing parts to be swapped or repaired easily. Design changes can be applied to individual components and not the entire propulsion system. The NASA Glenn innovation eliminates heavy shafts and disks, and allows
Erosion caused by the impact of water droplets on component surfaces can lead to failures in key technological applications. For example, in steam generating plants, the leading edge of turbine blades suffer major erosion damage from the steam driving the turbines, requiring costly maintenance and repair with consequent loss of generating capacity. Similarly, erosion caused
Lawrence Livermore scientists have collaborated with an interdisciplinary team of researchers including colleagues from Sandia National Laboratories to develop an efficient hydrogen storage system that could be a boon for hydrogen powered vehicles. Hydrogen is an excellent energy carrier, but the development of lightweight solid-state materials for compact, low-pressure storage is a huge challenge. Complex
The Air Force is increasing computer simulations and virtual testing for its laser-weapons program to accelerate development and prepare plans to arm fighter jets and other platforms by the early 2020s. To help model the effects of such technologies, the service has awarded Stellar Science a five-year, $7 million contract for advanced laser modeling and
In cooperation with the U.S. Army Research Development and Engineering Command, Army Research Laboratory (ARL), and Air Force Civil Engineer…
Anti-access and area denial — best known by its shorthand A2/AD — has crossed the buzzword threshold. It’s a quite impressive feat for such a distinctively non-user friendly and technical concept, which alludes to that family of military capabilities used to prevent or constrain the deployment of opposing forces into a given theater of operations
The emergence of China’s Beidou, Europe’s Galileo and Russia’s GLONASS satellites has multiplied the number of ionospheric piercing points (IPP) offered by GPS alone. This provides great opportunities for deriving precise global ionospheric maps (GIMs) with high resolution to improve positioning accuracy and ionospheric monitoring capabilities. In this paper, the GIM is developed based on
TEL AVIV — Israel Aerospace Industries (IAI) will debut at the upcoming Aero India exhibition in Bangalore an export-approved system to defend against GPS jamming. Called ADA after the special adaptive antennas developed by the firm’s MALAM division, the system is operational in Israel and is slated to be installed in yet another Israeli Air
To serve the soldiers of the future through connected devices, the military will need dynamic and adaptable networks. The Internet of Things is coming to the military in a big way, probably sooner than most think, according to the Army’s John Pellegrino. To make sure that tomorrow’s warfighters have all of the tools they need
