The United States is amassing an arsenal of abundant and easily made anti-ship weapons as part of American efforts to deter China in the Indo-Pacific region and gear up U.S. forces there. Russia's invasion of Ukraine has pushed U.S. thinking toward a new philosophy - "affordable mass," as one missile industry CEO put it, speaking on condition of anonymity, referring to having plenty of relatively cheap weapons at the ready. "It's a natural counter to what China has been doing," said Euan Graham, a senior analyst with the Australian Strategic Policy Institute think tank, referring to the Chinese arsenal of ships and conventional ballistic missiles including those designed to attack vessels.
