TOKYO – Japan’s Defense Ministry is inviting research proposals from private firms to advance the creation of compact rockets capable of swiftly deploying replacement satellites should current orbital assets be damaged or fail due to attacks.
A budget allocation of approximately 70 million yen ($444,000) has been set aside for fiscal year 2026 to support this research effort, with the goal of accelerating space transportation capabilities.
When evaluating submissions, the ministry will assess development expenses, production methods, and manufacturing timelines, with a decision on the selected contractor expected by February of next year.
The ministry is exploring the use of 3D printing and other advanced technologies to streamline rocket component fabrication and is weighing launch options across land, sea, and air platforms.
From a national security standpoint, rapidly restoring satellite functionality—especially in crisis situations—is essential,” Defense Minister Shinjiro Koizumi stated during an October press briefing, underscoring the urgency of rapid space access.
Currently, the Japanese government depends on foreign rockets for roughly half of its satellite launch missions.
Japan maintains a modest satellite network for surveillance purposes. Analysts have cautioned that both China and Russia are advancing “killer satellites” designed to target and disable other nations’ space assets.
The initiative aims to drive technological progress within the private sector and bolster the space industry, which the administration led by Prime Minister Sanae Takaichi views as a key growth domain.
Satellites are now essential for global communication and precise location tracking on Earth.
The realm of space transportation is stepping into a period of significant change. I envision a new, globally competitive system arising from our nation,” Koizumi stated.
