Main Obstacles in Hypersonic Production
Materials and Supply Issues
Hypersonic flight pushes materials to their limits, with components needing to endure extreme heat and stress. Temperatures in the vehicle's shock layer can soar to around 18,000°F (10,000°C), all while maintaining structural stability.
Here are some of the current material challenges:
Carbon-carbon composites: These materials, vital for aeroshells and leading edges, begin to oxidize at roughly 698°F and degrade quickly above 932°F.
Ultra-high temperature ceramics (UHTCs): Advanced ceramics like ZrB₂-SiC offer impressive strength (over 460 MPa at around 4,532°F) and resist oxidation up to 3,002°F. However, scaling up their production remains a hurdle due to the complexity of manufacturing processes.
Adding to the problem, the domestic supply chain heavily depends on foreign sources, making it vulnerable. These material limitations also affect production techniques, leading to further challenges in manufacturing.
Manufacturing Process Challenges
Producing hypersonic systems demands new approaches that go beyond traditional methods. Keith DeVries, Deputy Director of the Office of the Secretary of Defense's Manufacturing Technology Program, highlights the role of additive manufacturing:
"Being able to incorporate additive manufacturing is enabling us to manufacture complexity that has not been able under the subtractive, traditional manufacturing methods."
The Pentagon's hypersonic research budget increased to $4.7 billion in FY2023, up from $3.8 billion in FY2022. Despite this, several key manufacturing challenges remain:
Challenge Impact Current Solution Approach Thermal Management Components face temperatures above 3,272°F Advanced cooling systems and material engineering Complex Geometries Traditional machining is limited Additive manufacturing allows single-step production Production Speed Long lead times slow scaling Consolidating production steps to save time
These manufacturing difficulties also worsen supply chain vulnerabilities.
Supply Chain Risks
The precision needed for hypersonic production requires a dependable and secure supply chain. John Keller, editor at Military & Aerospace Electronics, warns:
"Contractors engaged in these areas must be vigilant about their supply chain vulnerabilities. They also need to know the regulatory risks of foreign investment, including review and potential intervention by the Committee on Foreign Investment in the United States (CFIUS)."
The current manufacturing base isn't equipped to meet the Department of Defense's ambitious goals. To address these gaps, manufacturers are:
Building partnerships with allied nations to diversify raw material sources
Shifting production to North America, even with higher labor costs
Creating steady demand signals to ensure suppliers can justify investments
At Texas A&M Engineering Experiment Station, researchers are applying additive manufacturing to propulsion systems. This approach enables the creation of more efficient fuel injectors and fluid passages without adding significant weight - an important step toward overcoming both manufacturing and supply chain challenges.
New Solutions for Hypersonic Manufacturing
Modern Production Methods
The Purdue Applied Research Institute's HAMTC is pushing the boundaries of ceramic component production through digital light processing. This method uses UV curing to achieve precision at the micron level.
Professor Rodney Trice from HAMTC elaborates:
"This allows you to produce intricate designs and geometries with very smooth surfaces and with a level of precision at the micron level... Through this process, we have succeeded in printing a variety of shapes, such as sharp cones and hemispheres, which are used to build a hypersonic vehicle."
These advancements tackle earlier manufacturing challenges by improving both accuracy and efficiency. For instance, Aerojet Rocketdyne was awarded a $22 million contract in 2023 to develop a 3D-printed hypersonic propulsion prototype using metal 3D printing, with delivery expected by early 2026. These innovations pave the way for a more decentralized and resilient manufacturing framework.
Distributed Production Networks
Decentralized manufacturing hubs address vulnerabilities in traditional production models. This method provides several key benefits:
Benefit Impact on Manufacturing Enhanced Resilience Multiple production sites reduce risks from disruptions Improved Response Local hubs can quickly adjust to changing demands Resource Optimization Better material use and lower transportation costs Sustainability Reduced logistics needs and greater material efficiency
The GAMMA-H project, launched in October 2023 with a $106.7 million budget, is a prime example of this approach. It empowers smaller manufacturers to contribute to defense projects while cutting down on part inspections and shipping.
Smart Supply Chain Management
AI is revolutionizing supply chain operations, helping businesses anticipate and respond to disruptions. Companies using AI-driven supply chain tools have seen a 40% boost in operational efficiency, a 50% drop in forecasting errors, and a 65% reduction in lost sales opportunities.
These gains come from AI's ability to analyze vast datasets and predict issues in real time. As a result, automation in supply chains is expected to double within the next five years.
PwC emphasizes the impact of AI:
"AI applications have the power to transform the way business is done and contribute up to $15.7 trillion to the global economy by 2030."
The integration of the Industrial Internet of Things (IIoT) complements these advancements, enabling tailored customer services while maintaining efficiency. Together, these technologies are shaping a more agile and responsive manufacturing ecosystem for hypersonic systems.
Developing Skilled Workers
Training Programs and Education
The aerospace workforce has drastically decreased, dropping from about 10,000 during the National Aerospace Plane era to fewer than 3,000 today. With many workers nearing retirement, there's an urgent need for fresh training strategies.
To address this, the American Ceramic Society (ACerS) and the United States Advanced Ceramics Association (USACA) introduced a DoD-funded program. This initiative includes short courses like UHTC Materials and Properties for Hypersonic Applications, blending theoretical knowledge with hands-on training at Oak Ridge National Laboratory.
Missouri S&T also offers specialized hypersonics courses:
Course Title Duration Schedule Hypersonic Vehicle Design and Integration 10 weeks 2 hours, twice weekly Hypersonic Aerodynamics and Propulsion 10 weeks 2 hours, twice weekly Hypersonic Materials and Structural Analysis 8 weeks 2 hours, twice weekly
"We have to develop a new workforce to rediscover what we knew in the 1950s - and then develop the next level of hypersonic vehicles."
Thomas Corke, director of Notre Dame's Hypersonic Systems Initiative
Building a skilled workforce is just as important as advancing technology to ensure the hypersonic manufacturing ecosystem thrives.
Hiring and Keeping Expert Staff
With over 46% of the federal STEM workforce under its umbrella, the Department of Defense views this issue as a national security priority.
Purdue University's Hypersonics Advanced Manufacturing Technology Center (HAMTC) is tackling this challenge head-on. Backed by an $18.6 million contract, HAMTC partners with leading companies like GE Additive, Dynetics, and Lockheed Martin. This collaboration gives researchers and students hands-on experience solving real-world industrial and defense problems.
"What is unique about this is our ability to work hand-in-hand with industry. We'll have researchers and students work on real industrial and defense problems, while at the same time advances and transitioning innovations in high temperature materials and cutting-edge additive manufacturing."
Michael Sangid, executive director of HAMTC
Early exposure to the field is also essential. Lori Stiglitz, workforce development lead at the JHTO Systems Engineering Field Activity at Naval Surface Warfare Center, Crane, emphasizes the importance of introducing young students to hypersonics:
"Research has told us that second graders around the age of 7 or 8 start to limit their career choices...if they don't start hearing the terms hypersonics and what that can mean, then they start limiting their options."
The sector faces additional hurdles, including stiff competition and a lack of diversity. Kimberly Jacoby Morris, STEM program coordinator at the Air Force Office of Scientific Research (AFOSR), highlights these challenges:
"There are a lot of different offices that are now focusing on STEM literacy, STEM workforce development... We know that our adversaries are outpacing us in the production of Ph.D. candidates from highly qualified universities. We also know that we have a diversity problem within the STEM workforce."
Protecting Defense Supply Lines
Working with Allies
The AUKUS security pact between the United States, Australia, and the United Kingdom kicked off with the Hypersonic Flight Test and Experimentation (HyFliTE) project. Supported by $252 million in funding, the initiative aims to complete six flight test campaigns by 2028.
"We are increasing our collective ability to develop and deliver offensive and defensive hypersonic technologies through a robust series of trilateral tests and experiments that will accelerate the development of hypersonic concepts and critical enabling technologies."
– U.S. Undersecretary of Defense for Research and Engineering, Heidi Shyu
In August 2023, Japan and the United States joined forces to develop the Glide Sphere Interceptor. Japan allocated 75.7 billion yen (around $490 million) for the initial phase, focusing on tip design and rocket motor development.
These partnerships highlight the importance of international collaboration in strengthening and modernizing the defense supply chain.
Digital Security Measures
Spirit AeroSystems follows Cybersecurity Maturity Model Certification (CMMC) guidelines, using blockchain-based systems to secure digital supply chains.
The Pentagon’s cybersecurity protocols for hypersonic technology development include:
Security Focus Area Implementation Strategy Supply Chain Mapping Multi-tier visibility tracking Active Monitoring Real-time threat detection Supplier Risk Scoring Evaluation and scoring of suppliers Predictive Analytics Forecasting disruptions and optimizing inventory
"Our biggest sustainment concerns with hypersonics are ensuring that subcomponents have a resilient supply chain with secure microelectronic components and that the … military services have a strategy for spares and repairables that provide sufficient annual quantities to ensure predictability for suppliers and readiness for the warfighter."
– Ellen Lord, Undersecretary of Defense for Acquisition and Sustainment
These cybersecurity efforts work alongside regulatory measures to safeguard the supply chain.
Trade Rule Compliance
The National Defense Authorization Act (NDAA) for FY 2025 introduces initiatives to protect U.S. advantages while fostering international cooperation. For instance, a $14.3 million contract was awarded to Anduril Industries Inc. to boost domestic solid rocket motor production.
Key NDAA priorities include:
Strengthening critical materials production
Enhancing defense industrial base resilience
Protecting infrastructure
Securing supply chains
Efforts like these aim to reduce reliance on foreign suppliers while maintaining key international partnerships. The U.K.’s Hypersonic Technologies and Capability Development Framework reflects this balance, involving over 90 suppliers and a commercial capacity of up to 1 billion British pounds.
How The U.S. Fell Behind In Hypersonic Technology
Conclusion: Next Steps for US Manufacturing
The future of US manufacturing lies in tackling current challenges and pushing forward with transformative efforts. The hypersonics supply chain, in particular, highlights pressing issues in scaling production, which are crucial for maintaining America's strategic advantage.
Recent actions by the Department of Defense underscore the urgency of this transformation. In April 2023, three significant contracts were awarded to boost domestic manufacturing capabilities:
Company Contract Value Focus Area Timeline General Electric $8 million High-temp composites, aeroshell production 39 months Northrop Grumman $9.4 million Ultra-high temp composites, automated manufacturing Not specified Carbon-Carbon Advanced Technologies $7.6 million Large complex C-C assemblies 38 months
However, the supply chain remains fragile. With only three carbon-carbon suppliers and two ammonium perchlorate suppliers, these bottlenecks expose a critical weakness.
"We assess that the current hypersonics supply chains - including the manufacturing base, supply of critical materials, testing infrastructure, and workforce - are incapable of supporting deployment of hypersonic weapons at scale", said Rebecca Wostenberg, research fellow at NDIA.
Emerging technologies are offering new possibilities. Companies like Ursa Major are utilizing 3D printing to bypass traditional manufacturing hurdles. Sabrina Ames, mission program manager at Ursa Major, shared:
"3D-printing technology allows us to bypass the constraints of traditional manufacturing processes... With additive technology, we can produce higher-performing fuel injectors and make fluid passages that mix fuel and oxidizer much more efficiently without adding significant mass to the parts."
This shift toward more agile production methods highlights the potential for a more resilient manufacturing infrastructure.
Addressing these challenges requires a comprehensive strategy:
Material Supply: Increase domestic production of high-temperature composites and rare earth materials.
Workforce Development: Establish specialized training programs, supported by the addition of three new academic hypersonic wind tunnels each year.
Infrastructure Modernization: Upgrade manufacturing facilities and testing capabilities to meet future demands.
Supply Chain Security: Strengthen cybersecurity measures and protect intellectual property.
The path forward depends on resolving supply chain bottlenecks, adopting advanced manufacturing techniques, and ensuring sustained government support. Laura Taylor-Kale, assistant secretary of defense for industrial base policy, emphasized:
"The Biden Administration has identified hypersonics technology as a critical need for ensuring American national security."
