First Island Chain Deterrence Act

This bill requires the Comptroller General of the United States to submit a report within 18 months on how delays in U.S. weapons sales to Japan, Taiwan, and the Philippines affect the ability to maintain a strong defense posture in the First Island Chain region. The report must examine the benefits of these arms deliveries, identify specific delays in approved sales, and assess how production constraints or prioritization issues impact defense capabilities. It also requires the Secretary of Defense to provide necessary information to support this independent review. The legislation focuses on improving transparency around foreign military sales and their strategic implications for regional security.
