The U.S. Army's infostructure is falling into formation under a new command that is responsible for the operation, management and defense of that service's information systems worldwide. The organization's mission-provide a high-speed, secure, interoperable knowledge enterprise across the Army and around the globe that plugs into joint systems and the Global Information Grid.

Buoyed by pinpoint impact and target destruction of successive ballistic missile test warheads in space, the U.S. Navy and the Missile Defense Agency are moving to more difficult engagement scenarios. This sea-based element of ballistic missile defense builds on the existing Aegis weapon control system and Standard Missile infrastructure to extend battlespace.

Participants in the Joint Warrior Interoperability Demonstration are reeling from the triumph of this year's event, not only because all the pieces came together successfully but also because the lessons learned promise to provide real support to today's warfighters. In addition to focusing on interoperability issues, other substantive items were addressed, including the unique challenges of operating in the Pacific Theater, handling information disclosure problems and ensuring that network vulnerabilities are identified. Broad and successful foreign involvement in the U.S.-sponsored event confirmed that collaboration among nations is essential to defeating today's adversaries.

Defense in depth is the key to securing what will be one of the world's largest intranets. The U.S. Navy is using a layered approach to protect the systems that will connect all of its land commands and, through satellites, its ships at sea.

Members of the U.S. armed forces will gather this month to participate in a major joint integrating experiment that could change the way the nation engages adversaries in the near future. According to military leaders, the experiment is the culminating point for assessing how the United States can conduct rapid, decisive operations in this decade.

Researchers are developing a prototype technology that may replace traditional command posts. The system consists of manportable, lightweight computers loaded with battle management software and collaboration tools. The devices will permit commanders to conduct highly mobile operations while maintaining situational awareness and connectivity to superiors and subordinates across the battlefield.

An event that has become a staple of advancements in military technology has undergone an evolution and now aims at providing theater commanders with immediate solutions to operational interoperability problems before systems move into the field and are tested under fire-live fire.

The U.S. Navy is launching a new initiative that expands the concept of network-centric warfare from the purely technical world to the operations doctrine domain. The paradigm will affect every aspect of the Navy-from acquisition processes to transportation, from information sharing to targeting. Military leaders believe this new approach will increase combat effectiveness and better support joint and coalition operations.

High-temperature superconducting materials discovered only 15 years ago now are enabling signal filters that can achieve performance levels not even approached by conventional filters. Virtually any commercial or military system that must pull weak radio frequency signals out of background noise can benefit from the new technology.
