NATO Burden Sharing Report Act

This bill requires the U.S. Secretary of Defense to submit an annual report to Congress by March 1st detailing NATO allies' contributions to shared defense. The report must include each member country's defense spending (as a percentage of GDP), participation in military operations, defense industrial base health, military force structure, and support for Ukraine. It directly affects all NATO member countries and nations in the NATO Membership Action Plan, as their data is collected and assessed. The report aims to inform Congress about allies' defense commitments and resource allocation, supporting transparency in transatlantic security cooperation.
