A ship sailing inside a building, a periscope view on a PC and F-18 pilots located thousands of miles apart yet flying in formation are just some of the new teaching tools simulators now are enabling for the U.S. Navy. Computing advances and that touch of illusion that only the entertainment industry can create immerse both new and experienced sailors in virtual environments that suspend reality and convince them that what they see, smell, hear and feel truly surrounds them. The opportunities these capabilities offer are melding the Navy's training and operational environments and shrinking the time from learning to doing.

After five and a half years in which you have entrusted in me a leadership position at AFCEA International, it is now time for me to step down as president and chief executive officer.

In his book Capitalism and Freedom, Nobel Laureate Milton Friedman states that government by its nature contributes "enormous inertia—a tyranny of the status quo—in governmental arrangements. Only a crisis, actual or perceived, produces real change." As a result of the crises caused by Hurricane Katrina and the tsunami that ravaged Indonesia, Congress pressured the U.S. Defense Department to deliver government-based information-sharing services to assist citizens struck by natural or manmade disasters. The need to access, share and disseminate information to save lives by rapidly coordinating humanitarian relief is paramount.

U.S. Marines providing on-site command, control, communications, computers and intelligence support have a new tool—a tactical network in a box—that allows them to learn to use the most recent software in a virtual environment.

New emerging ways to protect electronic data include methods to verify the identity of those who have rights to view specific material as well as to provide access to information through the Internet instead of through hard or soft copies. These approaches reduce the chances of personnel stealing or misplacing copies of confidential records, because data remains in one location. This capability is particularly important as the U.S. military shifts to a network-centric environment and officials look for ways to provide the right information access to the right people while prohibiting that information from the enemy.

To focus on technologies that have global- or theaterwide effect and that span the branches of the U.S. military, the Defense Advanced Research Projects Agency has combined its Advanced Technology Office and Special Projects Office to form the Strategic Technology Office. The office is determining what capabilities warfighters lack and finding solutions for current problems and potential needs.

The U.S. military services are turning their attention to energy practices and energy sources as a matter of national defense and security. As debates rage over oil costs and usage as well as the question of when peak oil—the highest rate at which oil can be pumped from the Earth—will be achieved, the service branches are examining ways to use fuel more wisely and exploring alternative energy sources. While experts disagree on many energy issues, most agree that the United States needs to develop renewable and sustainable energy options now to prepare for the future, and the military must take a lead role in that paradigm shift.
