 U.S. to buy Patriot missiles from Japan to keep supplying Ukraine. Japan is set to officially make a policy change, allowing it to export several dozen Patriot missiles to the United States, bolstering Washington's arsenals, according to the Washington Post. Japan manufactures Patriot missiles, a leading U.S. missile defense system under a license from Raytheon. President Joe Biden raised this issue with Prime Minister Fumio Kishida at Camp David in August during a historic trilateral summit with South Korea and again at an economic summit in San Francisco last month. Concerned that Russian aggression could prompt China to take similar actions against Taiwan, Japan has supported Ukraine, becoming the first East Asian country to join Western sanctions against Moscow. The Patriots will not go directly to Ukraine. Instead, Japan is considering sending dozens of missiles to the United States to replenish its stocks for Japan and the Indo-Pacific region. Tokyo has not provided a schedule, but decisions on certain figures are expected soon, according to an official. The considered munitions include PAK-2 and PAK-3 interceptors. PAK-2 is designed to destroy certain types of ballistic missiles by exploding nearby, while PAK-3 is a direct impact munition targeting missiles and aircraft with greater explosive power. The cost of advanced PAK-3 interceptors is estimated to be around four million dollars each.
