Japan invites private sector to develop replacement satellite rocket
Tokyo (ANTARA) — Japan’s Defence Ministry has opened the door to private companies submitting research proposals for the development of small rockets designed to launch replacement satellites quickly if satellites already in orbit are attacked or suffer a malfunction.
Around ¥70 million (US$444,000, or approximately Rp8.03 billion) has been allocated in the fiscal 2026 budget to support the research initiative, which aims to accelerate development of the space transportation system.
In assessing proposals, the ministry will review development costs, methods and the time needed to produce the rockets. The Japanese government plans to select the company that will carry out the project by February next year at the latest.
The ministry is also considering using 3D printers and other equipment to improve the efficiency of rocket-component production. It is examining whether launches could be conducted from land, sea or air.
“From a security perspective, it is vital to restore satellite functions promptly, particularly in an emergency,” Defence Minister Shinjiro Koizumi said at a press conference in October, stressing the need for rapid access to space.
According to the Japanese government, around half of the country’s satellite launches currently rely on rockets from overseas.
Japan operates a constellation of small satellites to monitor a range of targets. Some experts have warned that China and Russia are developing “killer satellites” capable of attacking and disabling other countries’ satellites.
Through the initiative, Japan’s Defence Ministry hopes to encourage technological innovation among private companies while supporting the development of the space industry. The sector is regarded by Prime Minister Sanae Takaichi’s government as an area with potential to drive economic growth.
Satellites have become essential infrastructure for communications services and accurate positioning systems on Earth.
“The space transportation sector is entering an era of major transformation. I hope a new system capable of competing globally will emerge from our country,” Koizumi said.
