Foreign Military Sales (FMS)
Foreign Military Sales (FMS) is a U.S. government program that enables the sale of defense articles, services, and training to foreign governments and international organizations through government-to-government agreements, managed by the Department of Defense with State Department oversight [citation:1][citation:2].
What Is Foreign Military Sales?
Foreign Military Sales (FMS) is a U.S. government program that enables the sale of defense articles, services, and training to foreign governments and international organizations through government-to-government agreements [citation:1][citation:2].
FMS is one of two primary methods through which foreign governments can purchase U.S. defense equipment—the other being Direct Commercial Sales (DCS), where transactions occur directly between U.S. companies and foreign buyers [citation:2].
Key Characteristics
Managed by the U.S. Department of Defense through the Defense Security Cooperation Agency (DSCA) [citation:2]
Conducted through formal government-to-government agreements [citation:1]
Covers defense equipment, services, and training
Requires State Department review and approval for consistency with U.S. foreign policy and national security objectives [citation:1]
Payments made by purchasing country to U.S. government, which then disburses funds to contractors [citation:2]
How It Works in Government Contracting
Foreign Military Sales appears after a foreign government submits a formal request for U.S. defense support through a Letter of Request (LOR). The U.S. government reviews the request, defines requirements, and issues a Letter of Offer and Acceptance (LOA)—the formal agreement document for FMS transactions [citation:2][citation:3].
The FMS Process: The Defense Security Cooperation Agency (DSCA) forwards all FMS cases to the State Department's Office of Regional Security and Arms Transfers (RSAT), which ensures proper review for consistency with U.S. foreign policy. Following approval, the Department of Defense manages the transaction and contracts with U.S. companies to deliver required equipment or services [citation:1]. Contractors do not sell directly to foreign governments under FMS.
Congressional Notification: Pursuant to Section 36(b) of the Arms Export Control Act, the Executive Branch must formally notify the Senate Foreign Relations Committee and House Foreign Affairs Committee when a potential FMS sale meets or exceeds specified dollar thresholds [citation:1].
Regulatory Framework
Foreign Military Sales is governed by several key legal authorities:
Arms Export Control Act (AECA) – Authorizes defense exports to foreign partners and provides the legal framework for FMS [citation:1][citation:9]
Foreign Assistance Act – Provides additional policy guidance [citation:1]
International Traffic in Arms Regulations (ITAR) – While ITAR governs Direct Commercial Sales, articles transferred via FMS are transferred under separate statutory authority and are not subject to ITAR authorization requirements [citation:4][citation:6]
Why It Matters for Contractors
Business implications: FMS allows contractors to access international defense markets through U.S. government-managed sales. It reduces foreign customer risk because the U.S. government acts as the buyer and intermediary, managing contracts, logistics, and post-sale support [citation:2].
Compliance impact: Contractors must meet strict compliance, export control, and security requirements. Long timelines and complex coordination can affect cash flow and program planning.
Strategic importance: Small businesses often participate as subcontractors or niche suppliers in FMS programs. The program includes long-term support commitments such as training, maintenance, and logistics [citation:2].
Financial considerations: Pricing includes equipment costs plus administrative charges, training, and support services. Some countries qualify for Foreign Military Financing (FMF)—U.S. government funding that helps allies purchase defense articles [citation:2][citation:5][citation:10].
FMS vs. Direct Commercial Sales (DCS)
Understanding the distinction between FMS and DCS is essential for contractors and foreign buyers:
Government Role: FMS: U.S. government acts as intermediary; DCS: Direct negotiations between contractor and foreign buyer [citation:2]
Sales Process: FMS: Government-to-government, slower with built-in oversight; DCS: Business-to-business, faster and more flexible [citation:2]
Oversight: FMS: Full government oversight from negotiation through post-sale support; DCS: Less direct oversight, focused on export license approvals [citation:2]
Financial Arrangements: FMS: Foreign buyer pays U.S. government, which pays contractor; DCS: Direct payment to contractor [citation:2]
Common Misconceptions
FMS is only used for large weapons systems.
While FMS covers major platforms like HIMARS, Apache helicopters, and Patriot missile systems, it also includes training, maintenance, logistics support, and smaller defense articles [citation:2][citation:5][citation:10].
Only major defense contractors can participate.
Small businesses often participate as subcontractors or niche suppliers in FMS programs [citation:2].
Contractors negotiate directly with foreign governments under FMS.
No. Under FMS, the U.S. government manages the transaction and contracts with U.S. companies; contractors do not sell directly to foreign governments [citation:2].
Frequently Asked Questions
What is the difference between FMS and Direct Commercial Sales?
FMS is government-to-government, with the U.S. government acting as intermediary. Direct Commercial Sales (DCS) involve contracts directly between U.S. companies and foreign buyers [citation:2].
Who pays for an FMS transaction?
The foreign government pays, sometimes using U.S.-provided financial assistance through programs like Foreign Military Financing (FMF) [citation:2][citation:5][citation:10].
Can small businesses support FMS programs?
Yes. Small businesses often participate as subcontractors or niche suppliers in FMS programs [citation:2].
Does FMS include training and support?
Yes. Training, maintenance, logistics support, and sustainment services are common FMS components. Letters of Offer and Acceptance (LOAs) include specific notes for training and travel allowances [citation:2][citation:3].
Are FMS transactions subject to ITAR?
No. Articles transferred via FMS are transferred under separate statutory authority and are not subject to ITAR authorization requirements, though they may require third-party transfer approval [citation:4][citation:6].

Strategic Importance
Foreign Military Sales is a critical instrument of U.S. foreign policy and national security strategy, enabling allies and partner nations to acquire American-made defense capabilities through a structured, government-to-government process [citation:1][citation:2].
For contractors, FMS provides access to international defense markets while reducing foreign customer risk through U.S. government management. The program strengthens global security partnerships, supports U.S. defense industry jobs across multiple states, and ensures interoperability with allied forces [citation:5][citation:10]. Understanding FMS requirements, compliance obligations, and the distinction from Direct Commercial Sales is essential for contractors seeking to participate in this vital segment of the defense industrial base [citation:2].
