Constant upgrades have readied an advanced Turkish air defense system for foreign sales. Developed as Turkey's first fully digital command and control architecture, the technology interfaces with a variety of sensor and weapons platforms to provide operators with a real-time picture of the battlespace. The system can direct low-, medium- and high-level anti-aircraft systems as part of a layered defense network.

While information technology is furnishing combatant commanders with situational awareness in current operations, cutting-edge capabilities now provide overall situational awareness to the commander in chief. In recent years, and particularly since September 11, 2001, enhancements made to the White House communications systems ensure that the president can stay connected to his troops-all the time and from any location. Like the transformation that is taking place throughout the military services, the technologies that support the president have evolved into a system of systems at breakneck speed.

The U.S. Department of Homeland Security went on a shakedown cruise in the military world with its inaugural participation in the Joint Warrior Interoperability Demonstration this summer. Department personnel discovered how useful the event can be to explore new technologies, while military personnel gained greater insight into homeland security needs and how to support U.S. emergency operations. Many lessons were learned by military and homeland security participants alike in areas that reached beyond technology.

Demands to increase information sharing and collaboration among government agencies are creating a growing requirement for easy-to-use security products that facilitate classified communications. Many organizations are now realizing the benefits of videoconferencing; however, information protection in this area generally involves support from communications security-certified personnel, and moving from unclassified to classified conferences requires cumbersome procedures.

The U.S. Army and the commercial sector are very much engaged in new and emerging technologies, and the service is extending the edge of the network. In the past, the Army network went to the tactical brigades through mobile subscriber equipment. With the deployment of the Joint Network Transport Capability-Spiral One (JNTC-S) providing some of the Warfighter Information Network–Tactical (WIN-T) capabilities to one of the next units to deploy to Iraq (the 3rd Infantry Division), the Army will be extending the network down to the battalion level. And, now the information technology network reaches in some cases down to the platform-the soldier and/or the weapon.

A few weeks ago, there was a story on the evening news about a waitress in Texas whose son is a Marine stationed in Iraq. Although his unit could communicate with the higher echelons, its members were having difficulty communicating with each other while on the battlefield. He asked his mom to go to a local electronics store, buy a set of walkie-talkies and send them to him. She was happy to help the war effort, but what she didn't anticipate was the hit the equipment would be with her son's buddies who wanted walkie-talkies of their own.

The National Geospatial-Intelligence Agency, fresh from assuming a new name less than a year ago, is striving to meet several self-imposed goals to address shortcomings and to confront the challenges of 21st century network-centric warfare. On its to-do list are converting fully to digital products and services; pursuing an e-business model; and transforming its architecture. It also seeks to pursue advanced forms of geospatial intelligence, including electromagnetic spectrum, and to mature the ability to capitalize on airborne collection. And, the agency's leadership foresees a need for two new headquarters facilities to deal with burgeoning responsibilities and an increased terror threat.

A Web-based decision support system developed by private industry and university researchers allows government and military emergency responders to build situational awareness pictures of an unfolding crisis. The support tool taps data from diverse sources, translates it to a common database and presents it according to user needs.

U.S. legislators are fighting to secure information systems on two fronts: the federal government and the private sector. And, they are worried that the government is underachieving badly at a most crucial time for information security.

The future of the network may be wireless, but without security there can be no wireless network access for the military, according to the U.S. Defense Department. The department has issued a set of guidelines establishing policy for the use of commercial wireless technologies in the Global Information Grid, or GIG. The goal is to exploit the advantages of emerging wireless technologies without compromising the very core of the military's network-centric doctrine.
