Impact assessment on the H3 launch vehicle of the combustion anomaly during the Static Firing Test of the Epsilon S Second-Stage Motor
After the combustion anomaly during the Static Firing Test of the Epsilon S Second-Stage Motor (E-21) on November 26, 2024 (JST), we assessed the impact of the accident on the Solid Rocket Booster of H3 (SRB-3) which uses a solid motor like the E-21.
Although the motor design of the SRB-3 is different from that of the E-21, we have re-evaluated, including some common points (igniter booster and some materials), the development results of the previous static firing tests and other tests, as well as the flight results up to the 4th H3 Launch Vehicle. As a result, we have confirmed once again that the design of the SRB-3 has all been well verified. Furthermore, we have reconfirmed that there is nothing unusual in the inspection data of the SRB-3 manufactured for the 5th H3 Launch Vehicle.
Based on these assessment results, we have determined that there are no concerns regarding the flight of the SRB-3.
