The ACES program aims to develop portable, battery‐powered atomic clocks with stability, repeatability, and environmental sensitivity approaching that of laboratory‐grade cesium beam frequency standards. “The history of human knowledge is reflected in our clock technology,” says Robert Lutwak, program manager for the agency’s Atomic Clocks with Enhanced Stability (ACES) project. …

US Air Force could soon begin testing light attack aircraft to see if they’re a viable option for close-air support. The work is being led by Air Force Strategic Development Planning and Experimentation Office. The office will conduct experiments that include live exercises and simulation, and it will help senior Air …

The vision for the future soldier is to be combat effective and also highly mobile, adaptive, networked, sustainable with total battle space situation awareness and information assurance. Therefore, he is equipped with night- vision goggles, radios, smartphones, GPS, infrared sights, a laptop as well as batteries to power them. He …

U.S. Senate Select Committee on Intelligence held a hearing on “Current and projected national security threats to the U.S” from Director of National Intelligence, James R. Clapper. The fast and radical change in the world and our threat environment is demanding reevaluations of the way we do business, expanding our …

The US Government has now tuned to Quantum sensors to detect stealthy Russian and Chinese submarines. Quantum sensors are measuring device that takes advantage of quantum correlations, such as states in a quantum superposition or entanglement, for better sensitivity and resolution than can be obtained by classical systems. Quantum sensors …

DARPA under its Extreme Accuracy Tasked Ordnance (EXACTO) program has developed a self-steering bullet that can hit moving targets at long ranges with great accuracy. During successful live fire tests in Feb 2015, an experienced shooter using the technology demonstration system repeatedly hit moving and evading targets. Additionally, even a novice …

The US Defense Advanced Research Projects Agency (DARPA) has moved to a third and final stage of an effort to launch medium-altitude long-endurance (MALE) unmanned aerial vehicles (UAVs) from US Navy’s relatively small surface ships like destroyers, frigates, and even freighters and expects an initial flight test in 2018.   …

The Top 10 Emerging Technologies 2016 list, compiled by the Forum’s Meta-Council on Emerging Technologies and published in collaboration with Scientific American, highlights technological advances its members believe have the power to improve lives, transform industries and safeguard the planet. It also provides an opportunity to debate any human, societal, …

The unmanned underwater vehicles (UUVs) depend on stealth as they conduct surveillance and reconnaissance and other missions in the deep oceans. With GPS signals unable to penetrate the ocean’s surface, these UUVs can rely on inertial sensors to provide acceptable positioning information during short missions. On longer missions, however, inertial …

Black phosphorous, named for its distinctive color, is a natural semiconductor with an energy bandgap, and highly promising material for electronic, optoelectronic and thermoelectric devices. Also called phosphorene as It belongs to class of two-dimensional crystals including graphene, boron nitride and molybdenum disulphide. A band gap is an energy band in …
