Invisible conflicts are erupting on the battlefield as U.S. and coalition troops compete for precious electromagnetic spectrum. These e-turf wars may be silent, but they can be as deadly as enemy fire when warfighters have to choose between disarming an improvised explosive device and calling for close-air support. To resolve this conflict, the U.S. Defense Department now has an organization whose primary mission is to ensure that all warfighters have the spectrum they need when they need it.

The convergence of media and services in commercial cyberspace has its counterpart in the defense arena, where experts are tapping commercial technologies and standards to provide seamless information access to warfighters and decision makers.

The U.S. military is developing a suite of software applications that will allow secure communications between different national computer networks. This capability is essential to both coalition operations and disaster relief missions.

The U.S. military is expanding its options for creating secure wireless networks in urban and remote areas. The capability will increase the speed at which networks can be created in an emergency while reducing the amount of materiel troops need to haul into an area.

The orderly structure of established nations' mighty militaries differs intensely from the structure of terrorist force organizations. In terrorist cells, distinctions between warfighters who trigger improvised explosive devices and those who detonate car bombs are miniscule. Battle cells may comprise as few as two or three people or as many as several dozen. Information sharing takes place incessantly, using everything from the Web to cell phones. As a force, terrorist groups are inherently flexible.

The unforgiving world that has taken shape after September 11, 2001, is changing both the nature of defense intelligence and its means of operations. Virtually every aspect of intelligence operations—collection, processing, analysis and dissemination—is changing to address new global threats and the transformation gripping the national security community.

The Strong May Beat the Weak, but the Smart Defeat the Strong. By Cmdr. Gregory E. Glaros, USN (Ret.)

In his March 2007 SIGNAL Magazine column, Greg Glaros says "There was never a technology they didn't like ...at a cost they could afford."

In a Naval Institute Press publication, Inside the Iron Works: How Grumman's Glory Days Faded, George Skurla, the former chief executive officer of Grumman Aerospace, and William H. Gregory describe the failures and downfall, 30 years ago, of one of our leading naval aviation manufacturers. After reading this obituary it is easy to draw parallels to the specter that has befallen many current defense companies and acquisition guardians. We all recognize that there are many other factors responsible—congressional political influence, policy dictums, service secretaries and chiefs of service. But doesn't anyone realize that the U.S. Defense Department is suffocating under unaffordable cost overruns, catastrophic failures in engineering design, poor manufacturing quality and incompetent technical government oversight?

A new class of mechanical devices with embedded electronics will allow personnel to access maintenance panels and equipment in aircraft and other platforms rapidly and without the use of tools. The technology permits the remote closing, locking and unlocking of fasteners via wireless handheld devices. The fasteners also are equipped with sensors to report their status and that of the structures immediately surrounding them, offering the potential for smart logistics and vehicle diagnostic systems.
