Japan’s ASM-3 Kai Hints at Air-to-Air Role in New Defense Budget

Japan’s FY2027 defense budget includes a line describing the ASM-3 Kai as an “air-to-surface/anti-air” missile, suggesting a possible air-to-air capability for the domestically developed supersonic anti-ship weapon. While full details remain undisclosed and officials have not confirmed a new variant, the budget underscores Tokyo’s push to expand standoff strike, air defense, and related systems, alongside mentions of AARGM-ER and other long-range missiles. The exact nature and testing of any air-to-air ASM-3 Kai remain unconfirmed, leaving room for interpretation about future capabilities.
