Transfer of Defense Articles: Foreign Military Sales (FMS)

CRS (Congress) · Christina L. Arabia ·

Executive Summary

The Foreign Military Sales (FMS) program facilitates the U.S. government's transfer of defense articles, services, and training to foreign countries and international organizations. Managed by the Department of State and implemented by the Defense Security Cooperation Agency (DSCA), FMS totaled $104.4 billion in FY2025, including significant arms sales to allies and partners. The process involves multiple phases from request to closure, with congressional oversight and end-use monitoring.

Why It Matters

This document is crucial for defense and geopolitical analysts as it details the U.S. Foreign Military Sales program, a primary mechanism for projecting U.S. influence, building partner capacity, and shaping global security dynamics through arms transfers. Understanding FMS policies, processes, and key actors is essential for assessing U.S. foreign policy and defense industrial base implications.

Key Takeaways

  • The FMS program, governed by the AECA, is the primary U.S. government-to-government channel for transferring defense articles, services, and training to foreign entities.
  • Recent executive orders (E.O. 14268, E.O. 14383) have reformed FMS policy to prioritize industrial capacity building and incentivize partner defense investment.
  • The FMS process involves five phases: Pre-LOR, Case Development, Case Implementation, Case Execution, and Case Closure, with strict congressional oversight and end-use monitoring.
  • In FY2025, FMS activities totaled $104.4 billion, with major sales to key allies like Israel, Egypt, and Japan, highlighting its strategic importance.
  • The program is distinct from Direct Commercial Sales and includes DOS-funded Foreign Military Financing (FMF) and DOD-funded Building Partner Capacity programs.

Strategic Relevance

The FMS program is a cornerstone of U.S. foreign policy and defense strategy, enabling the U.S. to strengthen alliances, deter aggression, and enhance global security through military assistance and arms transfers. Its strategic importance lies in its ability to shape regional power balances, support partner interoperability, and bolster the U.S. defense industrial base.
