Abstract: More than ever before, success in battle depends on effective command and control—but the increasing complexity and speed of modern engagements makes it ever more difficult to develop the comprehensive situational awareness upon which effective command and control depends. In the face of this increase in pace and complexity, developing systems to expose cost-effectively battle managers and weapons directors to the full range and scope of potential conflict situations is an ever-increasing challenge. This paper presents a distributed immersive command and control visualization system. Networked participants visualize and interact with the Virtual Battlespace based on a JSAF simulation from the first-person, tactical or strategic viewpoints using one of several different immersive devices. This paper also describes how the Virtual Battlespace visualization system can be extended for use in a variety of control tasks such as battle manager training, real-time command and control, and UAV swarm management. Battle managers can interact with both simulated and 'manned' entities using a mixed mode interface that includes wireless palmtop interaction. The system has been developed under the guidance of the Iowa National Guard's 133rd Air Control Squadron, which has also cooperated in the evaluation of the system.
