Japan and the US move ahead in co-developing hypersonic weapons interceptor as regional threats grow
Associated PressTOKYO — Japan and the United States on Wednesday signed an arrangement to jointly develop a new type of missile defense system as the allies seek to defend against the growing threat of hypersonic weapons, which are possessed by China and Russia and being tested by North Korea. The project was initially agreed between Japan’s Prime Minister Fumio Kishida and U.S. President Joe Biden at their summit last August and reaffirmed between the leaders during Kishida’s April visit to Washington. Japan’s defense ministry called it a “pressing issue” and noted that hypersonic weapons in the region have dramatically improved in recent years. The MDA has estimated the cost to develop the hypersonic missile interceptor will exceed $3 billion, including Japan’s share of $1 billion.
