Biologists and engineers are melding their expertise to develop robots that look more like a high-priced dinner than a high-explosive detonator. Taking their cue from nature, scientists are designing a sensor-toting techno-crustacean that can operate in sandy, rocky, undulating environments. For military troops, these devices could alleviate the hazard of underwater mines during beach landings and littoral zone operations.

The sea change occurring in military and government procurement processes today is rippling through large companies and affecting how they conduct business. Capabilities-based acquisition, super-size contracts and a reduction in the government work force are driving factors in a corporate transformation that includes scanning for business opportunities earlier than in the past, then teaming to offer best-of-breed systems.

The U.S. Navy is using virtual reality to build better warships. By molding data into three-dimensional images with cutting-edge computer systems, engineers can identify potential trouble spots on a vessel's hull and share the information with other design teams around the country. Virtual imaging systems allow engineers to evaluate many different hull types before expensive model testing or full-scale trials occur.

Sensors will swarm tomorrow's battlefields, allowing warfighters nearly complete situational awareness and denying enemy forces the ability to hide or maneuver without being observed. A recent U.S. Air Force wargame identified several technologies that may revolutionize warfare by 2020. Key to these applications is the use of datalinks in all platforms to create a flexible, redundant network that stretches from infantry units on the ground to satellites in geosynchronous orbit.

More than two years have passed since the September 11, 2001, terrorist attacks. In that time, the U.S. government has undergone a massive overhaul to meet the challenges of combating an elusive foe. A key part of this restructuring was the creation of the U.S. Department of Homeland Security, charged with coordinating the efforts of myriad federal, state and local agencies to locate, identify and neutralize terrorist threats on American soil.

The Office of Naval Research and the Naval Undersea Warfare Center are testing a commercial Web technology that will boost network centricity in the program management process. An enterprise weblog, a Web-based journal that supports information sharing, communication and collaboration all in one medium, is being employed during the test and evaluation phase of a night-vision technology project.

The transformation that is redefining our military, far from slowing down, is actually gaining speed as it reaches into every corner of military affairs. If we measure the success of military transformation by the rate of positive change, then we have done more to improve the way we fight over the past four years than was achieved over the previous 213.

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.

Sophisticated tracking and communications capabilities rapidly installed on military platforms in the Middle East helped U.S. and coalition commanders in Afghanistan and Iraq slice through the fog of war with near-real-time situational awareness. Blue force tracking technology provides information about the location of friendly and enemy forces as well as terrain and danger zones such as mine fields. Equipment installed on a variety of platforms continues to allow mission leaders, commanders and warfighters in locations from the Pentagon to the battlefield to see the same picture of and elements in the battlespace like pieces on a chessboard.

Military space activities increasingly are resembling their more terrestrial counterparts as their presence grows in military operations. The aboveworldly realm now has its own specific communications networks, surveillance and reconnaissance sensors and even weather reports. Soon, it may feature new reusable transport systems and weapons designed to maintain supremacy in the highest frontier.
