Self-destructing, vanishing electronics on the way - Story
January 28, 2016
A flock of small, single-use drones capable of making precise deliveries or completing other military missions and then vaporizing into thin air sounds suspiciously like science fiction, but the U.S. Defense Advanced Research Projects Agency (DARPA) and its partners participating in the ICARUS program have developed and are bringing this technology into the realm of reality.

Next-gen military radar system design innovations - Story
January 21, 2016
Gallium nitride (GaN) transmitters, radio frequency (RF) tiles, and solid-state modular 3-D radar are among the latest innovations in next-generation military radar systems to embrace commercial-off-the-shelf (COTS) components to reduce costs. Designers of these systems have also adopted modular design to streamline installation and maintenance.

Ada language seeing activity in universities - Story
July 27, 2015
Once considered a DoD-only programming language, "Ada" continues to evolve and is increasingly being taught in universities around the globe for high-integrity applications that demand safety, security, and reliability. The language, around since the early 1980s, is now undergoing a revival of sorts in industry and in academia.

DoD's new cyberstrategy includes academia partnering - Story
June 10, 2015
The U.S. Department of Defense (DoD) operates the world's largest network - a diffuse patchwork of thousands of networks - and, as you can imagine, it's a giant target for state-sponsored and other malicious cyberattackers. One of the biggest factors enabling cyberspace attacks is the fact that security simply wasn't factored in when the Internet was designed. It was intended to serve as an open system to allow scientists and researchers around the world to connect and share data quickly and easily, which it does, but at the same time it creates an Internet-security "Achilles' heel" that allows attackers to do the same.

Orion spacecraft's avionics designed for reliability in deep space - Story
March 13, 2015
Unlike those used in manned spaceflight platforms of the past, the avionics and other electronics used in NASA's Orion spacecraft are driven mostly by software and commercial processor technology ruggedized and radiation-hardened to endure extreme radiation and temperature fluctuations. Orion's updated avionics also can handle the severe acoustic and vibration environments associated with launch, orbit, a fiery reentry, and a saltwater landing.
