Japan's ASM-3 Kai supersonic missile may include air-to-air capability

Japan's Ministry of Defense budget documents describe the ASM-3 Kai as an 'air-to-surface/anti-air' weapon, suggesting the supersonic cruise missile—originally designed for anti-ship missions—may be gaining a counter-air role against large high-value airborne targets such as tankers, AWACS, or strategic bombers. The ASM-3 Kai is designed to replace the ASM-1 and ASM-2 missiles carried by Japanese fighters.

Why it matters: If Tokyo is adapting a Mach-3 ramjet anti-ship round into an AWACS-killer, it's designing for a Pacific fight where Chinese ISR and tanker constellations enable long-range strikes—and signalling that Japan sees air-breathing hypersonics as a cheaper counter to expensive crewed support aircraft than traditional air-to-air missiles with shorter legs.

Japan requests record $55.6 billion defense budget with new extended-range missiles

Japan's Defense Ministry requested a record budget of 8.9 trillion yen ($55.6 billion) on Monday, including funding for new extended-range missiles, submarine-launched missiles, and missile modules for underwater drones. The request also emphasises artificial intelligence for sharpening decision-making, part of Tokyo's broader shift toward long-range strike and autonomous systems.

Why it matters: Japan is now spending like a major continental power, not an island defence force—the submarine-launched and UUV missile programmes signal Tokyo is pursuing arsenal-ship concepts below the surface, spreading strike capacity across platforms China will find harder to pre-empt than airfields.
