The combatant command in charge of U.S. homeland defense is in the midst of creating a one-stop cyber shop for information. The initiative supports a trusted information exchange by laying the foundation of an emergency event management framework. Developers contend that the tool will proffer the data and knowledge that commanders, agency leaders and law enforcement personnel need to make appropriate decisions during a crisis, and it ultimately will capture the decision-making process so it can be reviewed after the event has ended.

The People's Liberation Army Navy recently introduced two domestically designed and built guided missile destroyers that include Aegis-type radars and related technologies. Known as Project 052C guided missile destroyers (DDGs), the ships feature Aegis-type phased array panels, vertical launch systems, long-range missiles and considerable command and control. These capabilities were not found on any previous Chinese-built DDGs.

Researchers have discovered a class of nanoscale devices that can self-assemble when exposed to light. These sub-microscopic structures may provide new methods for manufacturing electronic components such as photonic devices and memory storage systems for computers. Another potential application for the technology is in splitting water molecules to generate hydrogen for use as fuel.

The day may not be far off when microscopic machines embed a phone in an individual biological cell, decode a human genome or sniff scents with the acuity of the best-trained bloodhound.

The science of the very small has big military, economic and security implications for the future. From molecular manufacturing to incredibly smart chemical weapons, the raw materials and ultimate paraphernalia that nanotechnology will enable boggle the imagination of even science fiction aficionados. However, experts who scrutinize the science and significance of nanoscale devices differ on how this kind technology will affect future generations as well as on what should be done today to keep the United States out front in this field.

The Advanced Extremely High Frequency satellite is designed for point-on-demand instant communications, providing protected worldwide command and control access within fractions of a second to U.S. and allied warfighters. This spacecraft is taking shape with substantial technical improvements-new phased array antennas, advanced integrated circuits, more efficient waveforms and novel space-based thrusters.

The North American wireless market is poised for the introduction of next-generation applications that deliver sophisticated multimedia and data products to handheld devices. Within the next 24 months, a variety of third-generation technologies services will become available, allowing consumers and enterprises to conduct business and to access data more efficiently.

Optical fiber may be losing one of its last advantages over wireless as military experimenters have demonstrated the ability to establish secure Internet radio frequency links over more than three dozen miles. This capability can be established to serve land forces on the move, aircraft operating in a small area or ships sailing near unfamiliar coastlines.

Location and intelligence information that only recently was introduced to U.S. Army ground combat vehicles soon may find its way into the hands of the individual soldier. Army engineers working with industry partners are finding ways to move vital position-location information down past the command level. The result may be a two-way flow of intelligence between headquarters and individual soldiers on the ground.

The U.S. Army is leading the charge in securing the new networking frontier: wireless communications. Recognizing the benefits and vulnerabilities of staying connected without being tied to wires, the Army's leadership has developed a policy that highlights security and that has become the model for all the services as well as for the U.S. Defense Department. Industry offers critical components to help the Army and others comply with these policies by designing solutions and sharing best business practices.
