- Kratos Defense selected Odon, Indiana, as the site for Project Helios, a new mid-tier coupled arc jet and laser hypersonic materials testing facility, following a multi-state competitive review.
- The facility will provide aerothermal testing for hypersonic materials and complement existing national test ranges, serving all branches of the U.S. Armed Forces per Kratos' announcement.
Kratos Defense & Security Solutions has selected Odon, Indiana, as the site for a new mid-tier coupled arc jet and laser facility, the company announced, marking a concrete step forward for Project Helios.
The site selection followed what Kratos described as an extensive, multi-state competitive review. Michael Johns, Senior Vice President at Kratos, confirmed the process was genuinely competitive. “This was a highly competitive process with several strong candidate locations,” Johns said in the company’s announcement. Odon, a small city in Daviess County in southwestern Indiana, emerged from that review as the location that best meets the technical and operational requirements for the facility, according to Kratos.
The company cited support from local and state leadership, along with partnerships with utility providers Utilities District of Western Indiana and Hoosier Energy, as factors that contributed to the decision.
The facility addresses a specific and consequential gap in how the United States tests the materials that hypersonic weapons and vehicles are built from. Arc jet testing simulates the aerothermal environment that a hypersonic vehicle experiences during high-speed flight, subjecting material samples to the combined heat flux and shear stress that occurs when air at hypersonic velocities interacts with a surface. At speeds above Mach 5, aerodynamic heating reaches temperatures that can exceed 2,000 degrees Celsius on leading edges and nose caps, and the materials that must survive that environment need to be tested under conditions that closely replicate actual flight before they can be trusted in operational systems. The coupling of arc jet and laser capabilities in a single facility expands the range of thermal and radiative conditions that can be simulated, giving researchers tools to evaluate materials under combined heating modes that neither technology alone can fully replicate.
The “mid-tier” designation in the facility’s description carries real operational significance when measured against the existing U.S. test landscape. The country currently operates large-scale arc jet facilities at NASA Ames Research Center in California and at Arnold Engineering Development Complex in Tennessee, but access to those national-level installations is limited, expensive, and increasingly oversubscribed as the number of hypersonic development programs competing for test time has grown substantially in recent years. Mid-tier facilities occupy a different position in the testing ecosystem, providing higher throughput, lower cost per test, and more accessible scheduling for the material evaluation work that happens between laboratory coupon testing and full-scale system qualification. Kratos describes Project Helios as providing a critical bridge between laboratory material development and fielded system applications, which is precisely the gap that mid-tier arc jet capacity is positioned to fill for a defense community that has more hypersonic programs in development than the existing national ranges can comfortably support.
The timing of Project Helios reflects the urgency that has built around U.S. hypersonic development over the past several years. China has fielded operational hypersonic glide vehicles and is expanding its hypersonic weapons portfolio at a pace that has driven significant increases in American investment across the full research and development stack. Russia demonstrated the Kinzhal air-launched hypersonic missile in combat in Ukraine in 2022. Both developments accelerated Department of War spending on hypersonic offense and defense programs, and the test infrastructure that those programs depend on has struggled to keep pace with demand. A new mid-tier arc jet facility in Indiana does not solve the entire test capacity problem, but it adds throughput and accessibility at a point in the development pipeline where both are critically needed and currently scarce.
Dave Carter, President of Kratos’ Defense and Rocket Support Services Division, described the partnership with Indiana’s utility infrastructure as central to the site decision. “Their proactive engagement was invaluable as we determined the best home for this critical capability, which we are excited to make available to the defense community,” Carter said in the company’s announcement.
Arc jet facilities have substantial power requirements, with large installations capable of drawing tens of megawatts during testing operations, making reliable and high-capacity utility infrastructure a non-negotiable site requirement rather than a secondary consideration. Hoosier Energy and the Utilities District of Western Indiana’s engagement during the selection process addressed that requirement in ways that evidently distinguished Odon from the competing locations that participated in the multi-state review.
Kratos has built a substantial presence in defense test and evaluation infrastructure over the past decade, operating rocket propulsion test facilities, aerial target systems, and a range of specialized test services for the Department of War and other national security customers. Project Helios represents an expansion of that infrastructure into the aerothermal testing domain at a moment when hypersonic material evaluation capacity has become a recognized national security gap, and the company’s announcement describes the Odon facility as intended to serve all branches of the U.S. Armed Forces and the Department of War, positioning it as a shared resource for the broader defense community rather than a proprietary internal capability.
