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.

Makers of rugged computing systems are working to deliver the best of all worlds: rugged-designed military products that enable mission-critical reliance and reliability, while balancing it with the best technology, at a low cost with commercial off-the-shelf (COTS) components, and in the shortest possible timelag behind the commercial market.

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.

The U.S. Department of Defense's fleet of unmanned aircraft systems enables tactical intelligence, surveillance, and reconnaissance (ISR) - without endangering military personnel and at a lower cost than manned aircraft.
National Collegiate Cyber Defense Competition highlights cybersecurity skills and opportunities - StoryApril 07, 2015
The U.S. military says that it wants?6,000 new ?cyberwarriors? by?2016; the Pentagon has requested?a $5.5 billion cybersecurity?budget for FY2016, and?the Obama administration is seeking $14 billion. Cybersecurity has clearly emerged as?a national imperative.

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.

For force protection in tight areas such as coastlines and coastal zones, military leaders are leveraging small, compact surveillance radar systems. Mark Radford, CEO of Blighter Surveillance Systems, discusses this trend and talks about the technology behind small radars with Senior Editor Sally Cole. Edited excerpts follow

The U.S. Federal Communications Commission (FCC) is attempting to find a regulatory fix - striking a balance between national defense and economics - to eliminate electromagnetic spectrum inefficiencies. For now, this is making the exact role cognitive radio technology will play in the U.S. military's future unclear.

Since the end of World War II, sea mines have damaged or sunk four times more U.S. Navy ships than all other types of attacks. In the future, advances in fully autonomous Unmanned Underwater Vehicles (UUVs) - equipped with embedded computing technology - will play a key role in sea-mine countermeasures.
