Modify the requirements for transfers of United States defense articles and defense services among the Baltic states.

Summary

Allows Estonia, Latvia, and Lithuania to move U.S.-origin defense equipment or services among themselves without seeking prior U.S. approval and directs the U.S. Secretary of Defense to create a shared coalition key so the three countries can share HIMARS ammunition for training and operations. The change is limited to those three Baltic states and uses existing legal definitions for defense articles and services.

• Allows Estonia, Latvia, and Lithuania to retransfer U.S.-origin defense articles/services to each other without prior U.S. approval.
• Directs the Secretary of Defense to establish a common coalition key to enable HIMARS ammunition sharing among the three states.
• Uses existing federal definitions for "defense article" and "defense service" and defines "Baltic state" as the three countries.
• Applies only to transfers among the three Baltic states and does not extend authority to other countries.
• Aims to improve interoperability, training, and operational flexibility for Baltic militaries.
• Does not include new appropriations or broad changes to U.S. export-control law beyond the limited permission.
• Creates an administrative and technical task for the Department of Defense to implement and manage the coalition key.
• May reduce paperwork and delay for mutual support and logistics among the Baltic partners.
• Potential oversight or end-use monitoring questions remain unaddressed in the text.
