A recently developed individual navigation tool allows soldiers to know their precise location inside buildings or areas where global positioning satellite signals are jammed. By combining several technologies into a small, lightweight unit, the device would provide warfighters with a three-dimensional view of their position so they could retrace their path to exit an area. The equipment also could help civilian first responders such as fire, police and emergency personnel to find routes through damaged or smoke-filled buildings.

A family of advanced lightweight reconnaissance drones is enhancing the situational awareness of German army units in Afghanistan and Kosovo. Easily transported in ground vehicles, the aircraft feature an automated flight control and navigation system that does not require skilled pilots to operate and can be rapidly assembled. Designed for mobility and a minimal logistics trail, the aircraft can operate from forward areas without the need for a runway.

The most impressive new large guided missile destroyers (DDGs) of China's Peoples Liberation Army Navy, or PLAN, are the showcases of new operations and responsibilities beyond traditional coastal roles. The ships' new sensors, missiles and combat systems are mainly of Russian and Western origin. However, China now is faced with the challenge of operating and maintaining these advanced systems to create a credible threat to foreign navies in Far Eastern waters. This blue-water fleet primarily comprises ships that have been operational for years, but other more advanced ships are being built and may be deployed as soon as next year.

Interoperability with allied forces is a priority for Australia's military, and a program underway will deliver a multiphase, $600 million renewal of the Australian Defence Force's tactical communications systems. The program initially will rely on a bridging capability largely based on existing infrastructure that will be supplemented and ultimately replaced over at least the next decade in a series of phased improvements.

The Finnish Software Radio Program is meeting the software-defined radio requirements of a nonaligned nation and offering insight into alternative approaches to the U.S. Joint Tactical Radio System. The program concentrates as much on equipping forces to fight in high-intensity conflict as it does on equipping them for smaller peacekeeping roles. Along with supporting allied forces' equipment, it aims to support interoperability for disaster relief activities, nongovernmental organizations, and aid and emergency services work.

A European army's battlefield digitalization initiative has reached maturity with the wide-scale production of a networked command, control, communications and intelligence system for its mechanized forces. The equipment provides commanders with a near-real-time representation of the theater of operations and marks the location of all known allied and enemy forces on a digital interface. It also allows units such as infantry, artillery, armor and attack helicopters to share information to enhance situational awareness and reduce decision-making time.

The Swedish military is preparing the way for fielding its own soldier modernization program by 2010 with field trials beginning this year. In support of the effort, one company is developing its own soldier ensemble to meet Swedish requirements and to compete in the international market at both the system-of-systems and subsystems levels. Sweden pursued its own path in defense procurement and development throughout the Cold War, keeping pace with the latest defense technology in military and industrial terms while remaining strictly nonaligned. Industrial consolidation in Sweden with the acquisition of Celsius by Saab, Linkoping, Sweden, was the catalyst for development of the Saab Warrior soldier ensemble.

China's procurement of additional modern Kilo-class submarines for the People's Liberation Army Navy, development of second-generation nuclear attack and ballistic missile submarines, and continued production of improved indigenous diesel boats present a threat to the U.S. Navy and other antisubmarine forces. However, these submarines may present an even larger challenge to Chinese crews and support assets.

Planners for the Israel Defense Forces have directed their infantry systems development program to focus on the growing challenges of urban warfare. The country's future combat soldier program is delivering both technological and conceptual solutions to provide advanced communications, navigation and lethality in an integrated package to the infantry.

A number of advanced unmanned aircraft systems are poised to enter service with military forces across Europe. This is the result of a continentwide investment in robotic aerial vehicles representing advances in current vehicles and new platforms. The aircraft all share a modular design approach for rapid mission customization and versatility.
