Deterring Chinese Preemptive Strikes Act of 2023

This bill requires the Defense Secretary to survey U.S. aircraft shelters across the Indo-Pacific (including in the First, Second, and Third Island Chains) that are critical for responding to potential Chinese aggression against Taiwan but lack upgrades to withstand missile or drone attacks. Within 120 days of enactment, a classified report must identify these shelters, followed by a 60-day plan to implement protective improvements. The legislation directly affects U.S. military aviation assets in the region by mandating specific infrastructure upgrades to enhance aircraft survivability during attacks. It focuses solely on procedural defense planning, with no funding or policy changes beyond the survey and improvement plan.
