Military Supersonic Combustion Ramjet Market Report 2025

The military supersonic combustion ramjet market size has grown rapidly in recent years. It will grow from $1.0 billion in 2024 to $1.12 billion in 2025 at a compound annual growth rate (CAGR) of 12.2%. The growth in the historic period can be attributed to rising defense spending, growing demand for long-range precision strike capabilities, geopolitical tensions, focus on missile modernization programs, and increasing government R&D investments.

The military supersonic combustion ramjet market size is expected to see rapid growth in the next few years. It will grow to $1.76 billion in 2029 at a compound annual growth rate (CAGR) of 12%. Growth during the forecast period will be driven by greater investment in hypersonic missile programs, an increased emphasis on boosting air defense capabilities, more frequent testing of hypersonic glide vehicles, accelerated prototyping and testing efforts, and a strategic move toward developing reusable hypersonic systems. Key trends expected include progress in hypersonic technologies, the deployment of scramjet engines in emerging missile systems, the development of compact scramjet propulsion units, the use of novel heat-resistant materials, and continuing innovation in propulsion systems.

The increasing allocation of funds to defense budgets is significantly driving the growth of the military supersonic combustion ramjet market. Governments allocate defense budgets to cover military personnel, equipment, operations, and research and development. These growing budgets are largely a result of intensifying geopolitical conflicts, with nations enhancing military strength to safeguard national interests. A substantial portion of these funds is directed toward developing advanced propulsion systems like military supersonic combustion ramjets, facilitating faster, more efficient aerospace and missile technologies. For example, according to the Ministry of Defence in the UK, the nation’s defense budget increased from £52.8 billion ($66 billion) in 2022/23 to £54.2 billion ($67.8 billion) in 2023/24. This illustrates how growing defense spending is contributing to the expansion of the military supersonic combustion ramjet market.

Leading companies in the military supersonic combustion ramjet market are developing dual-mode scramjets to significantly improve the range, speed, and agility of hypersonic weaponry. Dual-mode scramjet engines function as ramjets during the lower hypersonic speed range and transition to scramjets at higher speeds, thereby maintaining propulsion efficiency across a broader velocity spectrum. As an example, in July 2024, General Electric Company, a U.S.-based aerospace firm, announced the successful testing of a hypersonic dual-mode ramjet engine. The engine achieved a threefold increase in airflow when compared to prior flight-tested hypersonic demonstrators. Developed in only 11 months, the system was validated at GE Aerospace’s high-speed propulsion test center and showed consistent, high-performance results - paving the way for advanced hypersonic weapons with extended range, faster speeds, and enhanced maneuverability.

In July 2023, L3Harris Technologies Inc., a U.S.-based technology firm, acquired Aerojet Rocketdyne Holdings Inc. for an undisclosed sum. This acquisition was aimed at reinforcing the defense manufacturing base, improving competitiveness, and accelerating technological innovation. By bringing Aerojet Rocketdyne’s expertise in propulsion and energetics into its portfolio, L3Harris seeks to expand its capabilities in advanced missile propulsion systems. Aerojet Rocketdyne Holdings Inc. is known for its specialization in the design and development of military supersonic combustion ramjet (scramjet) engines.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The sharp hike in U.S. tariffs and the associated trade disputes in spring 2025 are notably impacting the aerospace and defense sector by raising costs for titanium, carbon fiber composites, and avionics materials largely sourced from global suppliers. Defense contractors, locked into fixed-price government contracts, absorb these added costs, while commercial aerospace firms face airline pushback on higher aircraft prices. Delays in component shipments due to customs bottlenecks further disrupt tight production schedules for jets and satellites. The industry is responding by stockpiling critical materials, seeking waivers for defense-related imports, and collaborating with allied nations to diversify supply chain.

A military supersonic combustion ramjet is a type of air-breathing propulsion system developed for hypersonic speeds (typically exceeding Mach 5). It operates by compressing the incoming high-speed air without the use of moving parts and ignites fuel directly within the supersonic airflow. These propulsion systems are used in cutting-edge military technologies, such as hypersonic missiles and high-velocity reconnaissance aircraft, delivering extremely fast speeds, extended range, and shorter response times for critical defense operations.

The primary categories of military supersonic combustion ramjet systems include air-breathing ramjets, scramjets, and hybrid configurations. Scramjets represent advanced forms of air-breathing propulsion that support supersonic combustion, facilitating efficient propulsion at speeds surpassing Mach 5. These propulsion technologies integrate components like fuel injection systems, thermal regulation solutions, exhaust management systems, and advanced control technologies. Propellant options encompass liquid fuels, solid fuels, hybrid combinations, and alternative fuels. These engines are applied in missiles, UAVs, manned aircraft, defense technologies, and R&D initiatives, with end-users comprising defense contractors, government military agencies, aerospace manufacturers, and scientific research institutions.
