The Japan Space Exploration Agency (JAXA) is developing a concept design tool called SEAT (Systems Evaluation and Analysis Tool) to assist in evaluating candidate space transportation system concepts and selecting promising concepts for further development. The paper describes the SEAT development objectives, development strategy, and present status. The concept design of five systems that use the rocket, the Turbine-Based Combined Cycle (TBCC), and the Rocket Based Combined Cycle (RBCC) engine are also performed using the SEAT. The concept design is performed to minimize the gross take-off weight. The lightest system concept is the Two-Stage-To-Orbit (TSTO) using rocket propulsion for both stages in this design.
