Jack Rabbit II - Test Report

This test report summarizes the findings from Jack Rabbit II (JRII) conducted at WDTC, US Army Dug-way Proving Ground (DPG), Utah, from August 2015 through September 2016. It should not be construed as the Army Test and Evaluation Command system evaluation report or system assessment for JRII. The JRII test was designed to safely replicate accidental or intentional releases of chlorine gas from pressurized tanks and to document the downwind movement of the gas through an urban setting and in an open area. During 2015, five trials were completed in a simulated urban area containing multiple vehicles with chlorine gas releases ranging in size from 5 to 9 tons. Mass, pressure, chlorine vapor concentration, temperature, and meteorological data were collected to track the chlorine cloud movement downrange. During 2016, four trials were completed with minimal urban structures and vehicles, using chlorine gas releases ranging in size from 10 to 20 tons. Three chlorine dissemination angles were tested; 180 degrees (downward), 135 degrees and 0 degrees (upward). Data can be found on the Homeland Security Information Network (HSIN).
