Abstract This paper discloses an innovative methodology for the generation and update of technology roadmaps to support strategic decisions for future hypersonic transportation systems, specifically targeting non-profit oriented R&D. The methodology is fully integrated into up-to-date conceptual design activity flows. It consists of five main steps that through mathematical and logical models moves from stakeholders’ analysis up to planning definition and results evaluation. Complementary to the traditional experts-based methodologies, the rational process here presented allows for a well-structured logical definition of activities and/or missions required to enhance the readiness level of technologies, including a more accurate and reliable budget and time resources estimation to support the technology development plan. This methodology is exploited in the framework of the H2020 STRATOFLY Project to assess the potential of hypersonic civil vehicles to reach Technology Readiness Level 6 by 2035 with respect to key technological, societal and economical aspects. The paper discloses a unique assessment of the readiness level of the European air-breathing propulsive technologies. The final results confirm the crucial role of air-breathing propulsive technologies in the development of future hypersonic transportation system and highlight the urgent need to invest in in-flight demonstration missions with increasing functionalities, to target 2050 as entry in to service of the first Mach 8 civil transport.
