Joint Warning and Reporting Network (JWARN) 2
Print Friendly, PDF & Email


The Joint Warning and Reporting Network (JWARN) 2 provides joint forces with a capability to report, analyze and disseminate detection, identification, location and warning information to accelerate the warfighter’s response to a Chemical, Biological, Radiological and Nuclear (CBRN) attack. JWARN 2 is a computer-based application integrating CBRN data and facilitates sensor information into joint and service command and control systems for battlespace situational awareness. JWARN replaces the manual processes of incident reporting, hazard plot generation and warning affected forces.


JWARN reduces the time from incident observation to warning to less than two minutes, enhances situational awareness throughout the area of operations and supports warfighter battle management tasks.
