TOKYO – On Monday, Japan successfully launched a new defense satellite using its latest H3 rocket, aiming to enhance its military capabilities amid rising regional tensions. This significant mission took place from the Tanegashima Space Center, located on a southwestern island of Japan. According to the Japan Aerospace Exploration Agency (JAXA), the launch proceeded without any complications, and approximately 30 minutes post-liftoff, the satellite positioned atop the rocket was efficiently deployed as shown in their livestream coverage.
Later in the day, JAXA is expected to provide additional insights regarding the the launch’s specifics. The H3 No. 4 rocket was tasked with carrying the Kirameki No. 3 satellite, a project by the Defense Ministry that employs X-band communication. This technology facilitates military operations and reconnaissance missions, particularly in gathering intelligence concerning North Korean missile activities. Notably, X-band satellites are relatively less susceptible to weather disruptions and ensure stable communication. With this launch, the Kirameki No. 3 joins two previously operational X-band satellites, enhancing Japan’s aerial surveillance capacities.
Originally scheduled for October 20, the launch experienced four delays attributed to a combination of technical issues and adverse weather conditions. This successful mission marks the third consecutive triumph for the H3 rocket series after a disastrous inaugural flight last year, where the rocket had to be destroyed along with its payload due to failure. Japan regards a reliable and competitive space transport system as essential not only for its space exploration aspirations but also for bolstering national defense.
The development of the H3 launch system is a collaboration between JAXA and its primary contractor, Mitsubishi Heavy Industries (MHI). The H3 is set to replace the current H-2A rocket, which is nearing its retirement after two additional launches. MHI plans to eventually assume full control over the production and launches of the H3 rocket, with intentions to make it commercially viable by reducing launch costs to approximately 50% of those of the H-2A system.
