ECN-9353 This image shows three vehicle configurations considered for the Drones for Aerodynamic and Structural Testing DAST program, conducted at Dryden Flight Research Center between 1977 and 1983. The DAST project planned for three wing configurations. These were the Instrumented Standard Wing ISW, the Aeroelastic Research Wing-1 ARW-1, and the ARW-2. After the DAST-1 crash, project personnel fitted a second Firebee II with a rebuilt ARW-1 wing. Due to the project's ending, it never flew the ARW-2 wing.
