Japan tests a combined cycle jet and rocket engine. We are getting close to Macross irl with exo-atmospheric fighter jets.

I don't know how this is related to GCAP, and it mostly isn't. It's a Japanese new space news.

On August 30, 2024, the Ministry of Defense announced its budget request for fiscal 2025. Among them, we learned that 323.2 billion yen was requested for the construction of a “satellite constellation” using small satellites.

It is expected that satellite launches will begin at the end of FY2025, and the constellation will be built gradually, with full-scale operations to begin at the end of FY2027.

The Ministry of Defense plans to use the satellite as an “eye” to detect and track enemy naval vessels, ground forces, etc., in a stand-off defense capability to neutralize the enemy from a long distance using long-range missiles. In addition, a budget of 5.3 billion yen has been requested for the “Tactical AI Satellite Demonstrator Prototype,” which will use AI to process enemy data captured by other satellites and provide enemy information through intercommunication with various types of equipment.
