The People's Liberation Army Navy recently introduced two domestically designed and built guided missile destroyers that include Aegis-type radars and related technologies. Known as Project 052C guided missile destroyers (DDGs), the ships feature Aegis-type phased array panels, vertical launch systems, long-range missiles and considerable command and control. These capabilities were not found on any previous Chinese-built DDGs.

The People's Republic of China is building the necessary infrastructure to mine the ports of Taiwan should military conflict break out between the two governments. This capability would give China an effective blockade ability without the risk of escalation that would emerge from a direct military confrontation with the United States.

A key U.S. ally is digitizing its command and control architecture to increase the operational speed and agility of its ground forces. Built around a wireless backbone supported by software programmable radios, this system will reduce sensor-to-shooter cycles by streaming real-time data to commanders. Designed for both high- and low-intensity conflict, it will link all echelons from infantry squads up to the division level in a single network.

The Danish military is implementing a versatile software platform for its naval and land command and control systems that has proved to be an affordable means to support data fusion over legacy communications links. Featuring an open architecture, the platform provides generic command, control and communications functions and flexibility in subsystem integration. It is being installed on the country's new ships as well as being retrofitted onto existing vessels.

The French army soon may benefit from a prototype command and control system for helicopters that allows low-flying aircraft to share data in a tactical network. The technology features detailed digital terrain maps that can be viewed in the cockpit or from a groundstation before a mission. Mission-planning information and text messaging also can be transmitted via this airborne system.

In keeping with its approach to incorporating blue-water-navy technologies for possible littoral uses, China is deploying a number of antisubmarine warfare systems to support potential conflicts against adversaries equipped with the most advanced submarines under the sea. As with most of China's military, these systems constitute a mix of legacy import technologies with indigenous developments.

High-resolution displays are allowing U.S. troops operating in Korea to view and share an uncluttered, near-real-time common operational picture of the region so they can monitor activity and respond to it faster than could an adversary. The images can be shared both horizontally and vertically with warfighters located throughout the command's area of responsibility, providing not only situational awareness but also situational understanding.

The German army is fielding technologies to enhance its soldiers' lethality, situational awareness, survivability and operational capability. The new kit consists of an easily upgraded, modular system of body armor, integrated communications and night-vision equipment. Each squad member is fitted with a personal radio and a handheld digital assistant that can receive imagery and tactical data via a local wireless network. The new equipment already has been tested operationally in Kosovo and Afghanistan.

Europe's armed forces are using virtual reality to develop and integrate new technologies. Consisting of several networked facilities operating as a single entity, this research and design capability allows defense firms and their customers to test how systems operate before funds are committed for acquisition and production. This virtual testing center uses sophisticated modeling and simulation functions to create operational and training methodologies.

The cost of linking legacy systems with new technologies entering service across Europe has caused a major international firm to shift its operational focus. Faced with shrinking defense budgets and nations locked into large multi-year procurement programs, the European Aeronautics Defence and Space Company (EADS), Paris, recently underwent an internal realignment. The company shifted away from being a platform and subsystem provider to becoming a primary systems integrator. This distinction is important because smaller budgets mean that European defense ministries can no longer afford to duplicate the efforts of other nations. Instead, they must leverage the expertise of multinational defense firms through shared integration programs.
