This article surveys Japan’s successful deployment of the Kirameki 3 satellite using the H3 rocket. This launch marks the fourth flight of the H3 and solidifies its role as a next-generation rocket designed to replace the H-2A for various missions. The mission was deemed successful and is notable for the Kirameki 3 satellite’s classified military purpose, as it aims to enhance Japan’s defense communication capabilities. This would primarily be for secure communication within military operations.

The deployment of the Kirameki 3 satellite includes significant cyber and defense implications, particularly concerning secure military communications in Japan’s defense strategy. With rising cyber threats, satellites dedicated to military communications are crucial for maintaining secure, encrypted, and resilient communication channels. This satellite enhances Japan’s ability to operate independently in the cyberspace domain, reducing the risks of interception and cyber espionage by adversaries. The rocket’s successful deployment of this and future military satellites will inevitably support expanded space-based cyber capabilities, essential for modern military operations and information warfare.
