At the heart of the F-9A Suisei’s design is its cutting-edge stealth architecture, which combines Starcrest’s advanced shaping techniques with Japan’s proprietary radar-absorbing technologies. The airframe features serrated intakes, internal weapons bays, and blended fuselage-wing geometry, reducing radar cross-section across multiple threat bands while maintaining aerodynamic efficiency. To complement its low-observable shaping, the Suisei is coated with a next-generation radar-absorbent material (RAM) developed jointly by Mitsubishi and Starcrest, capable of dynamically adjusting its electromagnetic absorption profile to counter evolving radar threats. This dual-layered approach — shaping to minimize returns and adaptive coatings to absorb residual signals — ensures the Suisei can operate deep into contested airspace, achieving true first-look, first-shot, first-kill capability against even the most advanced adversary systems.

The joint development of the F-9A Suisei significantly enhances regional defense security, anchoring Japan’s ability to deter aggression while reinforcing allied interoperability in the Indo-Pacific. By pairing Mitsubishi Heavy Industries’ domestic expertise with Starcrest United’s proven stealth and systems technologies, the program creates a robust defense partnership that strengthens deterrence across the region. Economically, the Suisei brings new high-technology jobs and industrial opportunities to Japan’s aerospace sector, empowering suppliers, engineers, and research institutions to contribute directly to a 6th-generation platform. At the same time, the program bolsters Starcrest United’s role as a premier defense contractor, embedding the company more deeply within the Japanese market and creating long-term avenues for collaboration on next-generation systems. The Suisei thus delivers more than air superiority — it represents a fusion of strategic security, industrial growth, and enduring partnership between Japan and Starcrest United.
