Yomiuri’s lead story on Sunday reported that according to several government sources, the Air Self-Defense Force has decided to develop Japan’s first domestically produced standoff missiles capable of attacking warships from outside an adversary’s range. The ASDF will improve on the ASM-3 air-to-ship missile it developed in 2017 to develop a missile with a range of over 400 km. Yomiuri said the decision was made in response to the rapid advancement of the Chinese navy’s striking capability.
Meanwhile, Kyodo reported from Washington on Sunday on the disclosure by a diplomatic source involved in U.S.-Japan relations that final arrangements are underway between the USG and the GOJ to conclude an agreement on jointly developing a type of new radar that can detect at an early stage the hypersonic missiles being developed by Russia and China. Noting that the new radar will be installed on U.S. Navy Aegis warships, the article said the plan signifies the further integration of defense systems between the U.S. and Japan. Kyodo voiced concern that Japan may play a role in an arms race between the three military powers.
