Japan launched its Kirameki No. 3 defense satellite on Monday via the H3 No. 4 rocket from the Tanegashima Space Center, significantly advancing its military communication capabilities. The satellite was successfully placed into orbit, marking a step forward in Japan’s regional defense strategy as the country strengthens its military under a 2022 security strategy. The plan calls for Japan’s Self-Defense Forces to play an increased role in regional defense amid heightened tensions with neighboring China, North Korea, and Russia.
The Role of Kirameki No. 3 in Japan’s Defense System
Equipped with advanced X-band technology, Kirameki No. 3 joins Japan’s defense satellite network, enabling faster, more stable communication across the Ground, Maritime, and Air Self-Defense Forces. The satellite is less susceptible to weather-related interference, providing secure, high-speed data transfer between Japan’s military branches and deployed units. Maj. Gen. Yasuhiro Kato emphasized that the new satellite enhances Japan’s national security and boosts the operational capacity of its Self-Defense Forces, especially for overseas missions.
Kirameki No. 3 is set to undergo testing and enter a geostationary orbit above Japan by March, joining Kirameki No. 1 and No. 2 in undisclosed locations to form a robust military communication network.
H3 Rocket’s Successful Flight a Boost for Japan’s Space Program
This launch marks the third consecutive success for the H3 rocket, developed by the Japan Aerospace Exploration Agency (JAXA) in partnership with Mitsubishi Heavy Industries (MHI). Following a failed debut in 2022, this successful mission reinforces the H3’s reliability and potential as a competitive, cost-effective satellite launch option. JAXA President Hiroshi Yamakawa expressed relief at the mission’s success, which followed several weather-related delays.
MHI aims to produce six H3 launches per year and has already signed contracts with international satellite operators, highlighting the rocket’s appeal for commercial clients. By cutting costs by half compared to its predecessor, the H-2A, the H3 is poised to serve as Japan’s new flagship rocket, supporting both commercial and national security needs.
With this recent achievement, Japan positions itself as a reliable player in the global satellite launch market while reinforcing its national security objectives amidst ongoing regional security challenges.
