Work is ongoing at the Block 1 heater pit for the Hypersonic Test Capability Improvement (HTCI) project as night falls. A team of Arnold Engineering Development Complex engineers is heading up the HTCI Project, nicknamed “Project Phoenix.” The goal of the project is to transform the J-5 facility at Arnold Air Force Base, Tenn., to support future hypersonic weapon acquisition and research and development programs. The pit will house the heaters that allow the facility to test at hypersonic conditions. (U.S. Air Force photo)
