This mission is part of Japan’s ongoing efforts to enhance its military operations and communication systems, particularly in response to perceived threats from neighboring countries such as China, North Korea, and Russia.
Maj. Gen. Yasuhiro Kato, chief of the Joint Staff Systems Department, emphasized the importance of this satellite for national security, stating that it will facilitate high-speed data transmission across Japan’s Ground, Maritime, and Air Self-Defense Forces. It will also improve coordination with units deployed overseas for peacekeeping missions and exercises.
Successful Launch After Delays
This successful launch comes after several delays; it was initially scheduled for October 20 but faced multiple postponements due to technical issues and unfavorable weather conditions. The H3 rocket’s previous flight history includes a failed debut in March 2023 when a second-stage engine failure led to a self-destruct command being issued shortly after liftoff. However, since then, the H3 has successfully completed two subsequent launches earlier this year.
The Japan Aerospace Exploration Agency (JAXA) confirmed that the launch proceeded as planned, with the satellite successfully detached from the rocket approximately thirty minutes after liftoff. JAXA President Hiroshi Yamakawa expressed relief at the successful deployment of Kirameki No. 3, highlighting its significance for Japan’s space program and national defense strategy.
Strategic Importance of the H3 Rocket
The H3 rocket serves as a successor to Japan’s long-serving H-2A vehicle, which has been instrumental in the country’s space endeavors for over two decades. The development of the H3 rocket by Mitsubishi Heavy Industries (MHI) and JAXA aims to create a more cost-effective launch system while maintaining reliability. MHI plans to take over production and launches from JAXA, with aspirations to reduce launch costs significantly—potentially halving those associated with the H-2A.
The H3 rocket’s design incorporates advanced technologies that enhance its payload capacity and reliability, making it competitive in the global space launch market. With multiple contracts already signed with international satellite operators, including those from the U.K., France, and the UAE, MHI is positioning itself as a key player in commercial space launches.
Future Prospects
As Japan continues to bolster its military capabilities through advancements in aerospace technology, the successful launch of Kirameki No. 3 represents a critical step forward in ensuring national security amidst an increasingly complex geopolitical landscape. The Japanese government remains committed to enhancing its defense posture as it navigates challenges posed by regional adversaries.
n addition to military applications, the H3 rocket is expected to support civilian missions and contribute to international space exploration efforts. As Japan aims to establish a reliable and commercially viable space transport capability, this successful launch underscores its commitment to advancing both its national security interests and its position in the global aerospace industry.

Conclusion
Japan’s recent successful launch of a defense satellite via its new H3 rocket not only signifies technological progress but also reflects the nation’s strategic intent to strengthen its military operations and communication systems in response to evolving security dynamics in East Asia. As investigations continue into future launches and capabilities, Japan is poised to play a more significant role in regional defense initiatives while ensuring robust communication networks for its Self-Defense Forces.
This achievement marks another milestone in Japan’s space ambitions as it seeks to enhance its operational capabilities amidst growing global competition in aerospace technology.
