Japanese netizens boast about their own rocket: No one else in the world can match Japan except the United States!
A prominent Japanese manufacturing blogger loudly praises Japan's aerospace achievements: JAXA's reusable rocket RV-X has successfully completed vertical takeoff and landing tests. Thanks to its comprehensive strengths in materials, engines, precision control, and software, Japan has become unmatched globally outside of the U.S., marking the beginning of a revival for Japanese manufacturing.
But insiders know this claim is self-deceptive!
The RV-X rocket is only 7.3 meters tall, with a test flight lasting just 30 seconds and reaching a height of only a dozen meters. It doesn't endure the extreme heat and high speed of atmospheric re-entry, operating under extremely simple conditions—far from representing mature space technology. The actual H3 recovery rocket that will be used in the future will face temperatures exceeding a thousand degrees Celsius during landing, requiring precise control powered by high-temperature-resistant rare-earth magnets—precisely the Achilles' heel Japan cannot overcome.
Nevertheless, this doesn’t stop Japan from continuing its daydreams!
