The U.S. Army is testing a new technology that will enable a seamless connection between the wireless world and the landline world by means of tactical radio networking. Through the use of an already proven network infrastructure, the addition of a centralized routing capability within a family of current-generation tactical field radios has provided access to multiple forms of connectivity that were previously unattainable in the field.

Move over ships, aircraft and submarines, and make room on the waterfront for the latest component in the U.S. Navy's fleet-information systems. Although information technology has long been an integral part of the Navy, the service's newest command brings an increased level of support to fleet commanders and creates a clear operational focus for its networks, space activities and information operations.

While the individual armed services continue their march toward change, some forward-thinking military leaders are examining transformation on a larger scale-the realm of operations. Technologies likely to be available in the future will enable effects-based operations, a concept that may not replace conventional warfare but certainly could narrow its breadth.

In the 18 months following the terrorist attacks, the U.S. government has undergone a series of structural changes. At the state and federal levels, efforts are underway to enhance communications and information-sharing infrastructures among agencies and other organizations. Public institutions also have reached out to the private sector to form partnerships designed to protect vital national infrastructures.

The term network-centric warfare broadly describes the combination of emerging tactics, techniques and procedures that a networked force can employ to create a decisive warfighting advantage. According to John Keegan, author of A History of Warfare, it is similar to the significant warfighting developments of the industrial age and agrarian age in that network-centric warfare seeks to exploit an order of magnitude change in an underlying source of power to increase warfighting advantage dramatically. Paula Kaufman, in an article she wrote for IEEE Spectrum, agrees with this opinion. In the industrial age, power was primarily derived from mass and the sources of power for moving mass. In the information age, power is increasingly derived from information sharing, information access and speed, she says.

Major military failures frequently arise when leaders ignore fundamental changes in technology, doctrine or society. However, when leaders are seduced into believing that there is a fundamental change in technology or doctrine where none has actually occurred-for example nuclear weapons in Korea or the use of the helicopter in Vietnam-the result can be equally devastating.

The U.S. military will conduct its annual search for interoperability solutions next month with a renewed sense of urgency as nations continue to pull together to fight terrorism and government agencies pursue collaboration in homeland security efforts. Once again, this year, the focus will be on examining dozens of technologies that commands can employ to address immediate interoperability problems.

A push for force transformation across all branches of the military has brought about change in the research and development community and the collaboration technologies it creates. To meet the growing demand for accurate, relevant and timely information on the battlefield, scientists and engineers are focusing on interoperability, standards and advanced technologies.

An experimental communications system may soon connect U.S. Marine Corps units deployed on amphibious operations. Built using current satellite technology linked to radios and battlefield data management devices, the network will connect forward tactical units with task force commanders.

U.S. Marine Corps transformation efforts are seeking to keep humans at the center of an increasingly automated decision cycle. As the service morphs into a network-centric fighting force, planners are designing doctrine and technologies to serve warfighters' needs without burying them in excess information.
