DARPA’s Next RS Program: The Future of Hypersonic Aircraft

Introduction
The pursuit of hypersonic aircraft, capable of speeds exceeding Mach 5, has become a cornerstone of modern military strategy. These advanced platforms promise unparalleled speed and flexibility, enabling rapid strike and intelligence, surveillance, and reconnaissance (ISR) missions. As global adversaries develop increasingly sophisticated air defense systems, the U.S. military is doubling down on hypersonic technologies to maintain its strategic edge.
One of the most ambitious efforts in this domain is the Next Generation Responsive Strike (Next RS) program, spearheaded by the Defense Advanced Research Projects Agency (DARPA) in collaboration with the Air Force Research Laboratory (AFRL) and NASA. This initiative aims to develop a reusable hypersonic aircraft prototype by 2030, addressing critical technological gaps and operational needs. The program follows the uncertain trajectory of the Mayhem project, which faced funding and operational viability challenges, underscoring the complexity of hypersonic development.
The Next RS Program: A Leap Forward
Technological Foundations
The Next RS program focuses on six key technological areas: structures and materials, high-speed weapon separation, dual-mode propulsion, power generation, thermal management systems, and high-Mach turbine engines. These components are essential for creating a hypersonic aircraft capable of withstanding extreme physical and thermal stresses while maintaining operational efficiency.
At the heart of the program is the Turbine-Based Combined Cycle (TBCC) propulsion system, which combines traditional jet turbines with ramjets/scramjets. This dual-mode system allows the aircraft to take off and land using conventional runways while achieving hypersonic speeds during flight. The TBCC system is considered a “holy grail” in high-speed aircraft design, offering seamless transitions between subsonic and hypersonic modes.
“The TBCC propulsion system is a game-changer, enabling operational flexibility that was previously unattainable with traditional hypersonic designs.” – DARPA Aerospace Projects Office
Operational Capabilities
The Next RS aircraft is envisioned as a multi-mission platform, capable of both strike and ISR operations. Its hypersonic speed would allow it to penetrate heavily defended areas, gather real-time intelligence, and deliver precision strikes on time-sensitive targets. This capability is particularly valuable in scenarios where traditional ISR assets, such as satellites, are either too slow or predictable.
However, the development of such a platform is not without challenges. Designing payload bays that can safely open and release munitions at hypersonic speeds requires significant advancements in materials science and engineering. Additionally, the aircraft must be reusable, adding another layer of complexity to its design and maintenance.
Challenges and Opportunities
Technological Hurdles
One of the most significant challenges in hypersonic aircraft development is creating a propulsion system that can operate efficiently across a wide range of speeds. While ramjets and scramjets excel at hypersonic speeds, they are ineffective at subsonic and low-supersonic speeds. The TBCC system aims to bridge this gap, but its development remains a formidable task.
Another challenge is managing the extreme thermal and structural stresses encountered during hypersonic flight. Advanced materials, such as carbon-carbon composites and ceramic matrix composites, are being explored to address these issues. However, these materials must be both lightweight and durable, further complicating the design process.
Operational Debate
While the potential benefits of a reusable hypersonic aircraft are clear, there is ongoing debate about whether such a platform is the most cost-effective solution. Stand-off munitions, including hypersonic missiles, offer similar capabilities at a fraction of the cost and complexity. Critics argue that the resources allocated to hypersonic aircraft development could be better spent on other defense priorities.
“The question isn’t whether we can build a hypersonic aircraft, but whether we should. The operational benefits must justify the significant investment required.” – Military Aviation Analyst
Conclusion
The Next RS program represents a bold step forward in hypersonic aircraft development, aiming to deliver a reusable, multi-mission platform by 2030. While the technological and operational challenges are significant, the potential benefits—ranging from rapid strike capabilities to enhanced ISR—are equally compelling. The program’s success will depend on overcoming key technological hurdles and demonstrating clear operational advantages over alternative solutions.
Looking ahead, the development of hypersonic aircraft is likely to remain a priority for the U.S. military as it seeks to counter emerging threats and maintain its strategic edge. Whether the Next RS program achieves its ambitious goals or paves the way for future initiatives, it underscores the ongoing evolution of military aviation in an increasingly complex global landscape.

Embraer and Saab Sign Agreement for 20 Additional Gripens
Embraer and Saab signed a Heads of Agreement at Farnborough to produce 20 additional Gripen fighters in Brazil.

Embraer S.A. and Saab AB signed a Heads of Agreement (HoA) on July 21, 2026, establishing a framework to produce 20 additional Gripen fighter aircraft at Embraer’s facility in Brazil. The announcement, made during the Farnborough International Airshow, positions the companies to finalize a binding production contract later in 2026.
The agreement expands a decade-long industrial partnership between the two aerospace manufacturers and directly supports the Brazilian Air Force (FAB) requirement for additional tactical aircraft. According to official press releases from both companies, Embraer will assemble the new fighters at its Gavião Peixoto industrial complex in São Paulo State, complementing Saab’s primary final assembly line in Linköping, Sweden.
Expanding Brazilian production capacity
The HoA serves as a preliminary framework to allocate industrial responsibilities ahead of a formal contract. The move follows a June 4, 2026 announcement by the Brazilian government detailing plans to purchase 20 additional Gripen jets, supplementing the country’s original base order of 36 aircraft, according to reporting by Breaking Defense. That initial order consisted of 28 single-seat E models and eight two-seat F models.
Company leadership emphasized that the localized manufacturing model is designed to scale with regional requirements.
“The expansion of this partnership with Saab reflects the mutual trust built over the past ten years and reinforces Embraer’s strategic role in the Gripen programme. We are well positioned to support increased production capacity, if demand requires it,” said Bosco da Costa Junior, President and CEO of Embraer Defense & Security.
Recent program milestones and operational deployment
The framework agreement follows a series of recent milestones for the Brazilian Gripen program, designated the F-39E by the FAB. On March 25, 2026, Embraer and Saab unveiled the first Gripen E fighter assembled entirely on Brazilian soil at the Gavião Peixoto complex. Saab confirmed in a statement that this event marked the first supersonic fighter produced in Brazil.
Operational integration of the aircraft is also advancing. On July 14, 2026, the FAB deployed six F-39E Gripen aircraft to Chile for the SALITRE 2026 exercise. Saab noted that this marked the first time Brazilian-operated Gripens participated in a multinational exercise outside of Brazil.
“The partnership between Saab and Embraer reinforces our long-term commitment to Latin America. Together, we are strengthening our capabilities, securing additional capacity for future business opportunities, and taking a forward-leaning approach to supporting the evolving needs of our customers across the region,” stated Micael Johansson, President and CEO of Saab AB.

BAE Systems Unveils Brontanax UK Autonomous Combat Aircraft
BAE Systems and the UK MoD unveiled Brontanax, the UK’s first uncrewed CCA, at Farnborough 2026.

BAE Systems and the United Kingdom Ministry of Defence (MoD) unveiled Brontanax, the nation’s first uncrewed autonomous Collaborative Combat Aircraft (CCA), at the Farnborough International Airshow on July 22, 2026. The five-metric-ton aircraft is designed to operate alongside crewed fighter jets, providing electronic warfare and precision strike capabilities to the fleet.
According to a BAE Systems press release, the platform serves as the manufacturers offering for the UK government’s £300 million Storm Fighter program. The initiative aims to establish the Royal Air Force (RAF) as Europe’s first sixth-generation air force by integrating uncrewed systems with existing crewed fighters like the Eurofighter Typhoon and the Lockheed Martin F-35 Lightning II.
The Storm Fighter program and development timeline
Development of the Brontanax platform began internally at BAE Systems in 2022. The manufacturer has invested approximately £300 million to date to fund the project. The UK government formalized its financial backing on July 1, 2026, through its Defence Investment Plan, committing an initial £300 million to the sovereign autonomous combat air initiative.
UK Defence Secretary Wes Streeting highlighted the strategic importance of the platform during the unveiling event at Farnborough, noting the government’s intent to adopt the aircraft as an operational concept demonstrator.
“The unveiling of Brontanax, the UK’s first uncrewed autonomous Collaborative Combat Aircraft, is a testament to the extraordinary talent and innovation across our sovereign defence industry. Built at BAE Systems in Warton by British engineers, backed by British businesses large and small, this aircraft demonstrates that the UK has the skills, the technology and the determination to lead the world in combat air power.”
The prototype is scheduled for its first power-up in the third quarter of 2026. Ground trials are slated to begin in the first half of 2027, followed by flight trials in UK airspace in the second half of the year. The RAF plans to bring the aircraft into service before 2030.
Industrial footprint and supply chain realities
The Brontanax program currently involves more than 500 BAE Systems employees and engages over 75 UK companies and small-to-medium enterprises. The aircraft was designed and built at the BAE Systems facility in Warton, Lancashire.
While marketed as a sovereign British aircraft, the initial iterations of the drone utilize a US-made Williams International engine. BAE Systems and the RAF intend to transition to a British powerplant developed by Rolls-Royce for future production models.
Air Chief Marshal Sir Harv Smyth, Chief of the Air Staff, stated that the RAF is working closely with the manufacturer to meet the aggressive development schedule, confirming that a prototype is expected to fly next year.
AirPro News analysis
The unveiling of Brontanax signals the United Kingdom’s formal entry into the highly competitive CCA market. We are seeing a global surge in the development of these uncrewed systems, with aerospace manufacturers including Airbus, Boeing, Anduril, and General Atomics competing for contracts across multiple allied nations.
The primary driver behind this shift is combat mass. Traditional crewed fighters are highly capable but expensive to procure and operate. A large CCA is estimated to cost approximately 25 percent of a traditional crewed fighter. By pairing uncrewed systems with crewed jets, air forces can significantly expand their tactical footprint, sensor networks, and weapons capacity without a proportional increase in procurement budgets or pilot training requirements. The transition from the Williams International engine to a Rolls-Royce powerplant will be a critical milestone to watch as the UK attempts to secure a fully sovereign supply-chain for the Storm Fighter program.
