The United States sells billions in military equipment to foreign countries each year through a complex government program few Americans understand. Yet these sales shape global politics, strengthen alliances, and keep the US defense industry humming.
What is Foreign Military Sales?
Foreign Military Sales (FMS) is the US government’s primary way to sell military equipment and services to friendly countries and international organizations. Unlike commercial arms deals between companies, FMS is strictly government-to-government.
The program operates under the Arms Export Control Act, which lets the Department of Defense act as a middleman between foreign governments and American defense contractors.
Through FMS, allied nations can purchase everything from fighter jets and missile systems to training programs and maintenance services. The foreign government covers all costs—there’s no discount.
Each sale is documented in a Letter of Offer and Acceptance (LOA), essentially a contract between the US and foreign government.
Who Controls the Process?
Several US government agencies play crucial roles in military sales:
The Defense Security Cooperation Agency (DSCA) manages the day-to-day operations of the FMS program. They maintain the Security Assistance Management Manual, the bible for FMS procedures.
The State Department determines which countries can participate in FMS and approves individual sales. Its Bureau of Political-Military Affairs leads this effort.
The Department of Defense executes the program, with the Army, Navy, and Air Force handling specific sales as “Implementing Agencies.”
Congress provides oversight and must be notified of major arms sales.
Defense Finance and Accounting Service (DFAS) manages the money.
Security Cooperation Organizations in US embassies worldwide serve as the main point of contact for foreign governments. Examples include the Office of Defense Cooperation in Spain and Germany.
How the Process Works
Foreign Military Sales follow a structured path from initial interest to final delivery:
The Lead-Up
A foreign government identifies security threats and capability gaps in their military. They may hold competitions between various suppliers, including the US and other countries.
Getting Specifics
The potential buyer refines their requirements and explores options by requesting information from various sources. US military representatives often consult with them during this phase.
Making a Formal Request
The foreign government submits a Letter of Request (LOR) through their embassy’s Security Cooperation Organization or directly to DSCA. They can request either:
- Price and Availability data to evaluate options, or
- A formal Letter of Offer and Acceptance to initiate a purchase
Each request receives a unique case identifier. The DSCA Foreign Customer Guide provides guidance on preparing these requests.
Creating the Offer
The relevant military department reviews the case and prepares an LOA. This document details:
- Specific equipment and services
- Total costs
- Payment schedules
- Transportation arrangements
For major systems, a “Total Package Approach” is used, bundling the main equipment with training, spare parts, maintenance, and other support services.
For significant sales, Congress must be notified before the offer goes to the foreign customer.
Accepting the Deal
The foreign government signs the LOA and provides an initial deposit. Funding can come from their national budget or through US programs like Foreign Military Financing.
Executing the Sale
Once accepted, the military department implements the case in their systems, initiates contracts, procures the items, plans training, and oversees delivery. The Defense Logistics Agency may provide Excess Defense Articles if applicable.
Closing the Case
After all deliveries, services, and financial transactions are complete, the case undergoes reconciliation and is officially closed.
Benefits for the United States
FMS offers substantial advantages for American interests:
Strengthens Alliances: By equipping allies, the US builds lasting defense relationships that extend beyond the hardware itself.
Promotes US Influence: The program allows America to shape allied military capabilities and align partners with its foreign policy goals.
Supports the Defense Industry: FMS generates billions in annual sales, sustains American jobs, and can lower unit costs for the US military through economies of scale.
Enhances Interoperability: When allies use American systems, joint operations become smoother—crucial for NATO and other coalitions.
Shares Defense Burdens: FMS enables allies to invest in their own security, reducing pressure on US forces to defend them.
Benefits for Partner Nations
Foreign countries also gain significant advantages:
Access to Advanced Technology: Partners can acquire some of the world’s most sophisticated military systems.
Reliable Acquisition Process: The government-to-government framework provides security and reliability.
Comprehensive Support: FMS deals typically include long-term support packages covering maintenance, training, and updates.
Potential Cost Savings: In some cases, countries can purchase Excess Defense Articles at reduced prices.
Problems and Criticisms
Despite its benefits, the FMS program faces serious challenges:
Delays and Bureaucracy: The process often takes years to complete, frustrating foreign partners.
Lack of Transparency: Some countries complain about limited visibility into the status of their cases.
Congressional Bottlenecks: The review process, while necessary for oversight, can cause delays.
Industrial Base Constraints: The US defense industry sometimes struggles to fulfill orders promptly.
Technology Release Concerns: Worries about sharing sensitive technology can lead to extended reviews.
Inconsistent Prioritization: Strategic decisions about sharing major defense articles with allies can seem arbitrary.
Limited Accountability: Few senior officials face consequences for FMS delays.
Financial Oversight Issues: Government Accountability Office reports have highlighted concerns about cost recovery.
Ethical Concerns: Sales to countries with poor human rights records have drawn criticism.
FMS vs. Commercial Sales
Direct Commercial Sales (DCS) provide an alternative path for foreign buyers. Key differences include:
Transaction Type: FMS is government-to-government; DCS involves direct company-to-government sales with US oversight.
Risk Allocation: In FMS, the US government absorbs more contractual risk.
Negotiating Power: Foreign customers have greater leverage in DCS negotiations.
System Flexibility: DCS can offer more tailored, mission-specific systems.
Reliability Perception: FMS is often viewed as more transparent and reliable.
Support Packages: FMS typically includes more comprehensive long-term support.
Cost Structure: FMS may provide lower unit costs through consolidated purchasing.
Export Licensing: Unlike DCS, FMS cases are exempt from the normal export licensing process.
The Department of Defense generally remains neutral between FMS and DCS unless an item is designated “FMS only.” More comparisons are available on the DSCA website.
Recent Reform Efforts
Recognizing the need for improvement, the US government has launched several initiatives to enhance the FMS process:
Organizational Changes: The Department of Defense has established “Tiger Teams” and Continuous Process Improvement Boards to identify and implement solutions. The Defense Security Cooperation Service aims to professionalize security cooperation officers.
Process Acceleration: Initiatives focus on speeding up discussions with allies, reducing lifecycle delays, and better understanding partner needs.
Streamlined Reviews: Efforts are underway to expedite technology release reviews and provide priority capabilities, including systems not in the standard US inventory.
Acquisition Improvements: The DoD is working to accelerate contracting, establish performance standards, and expand industrial capacity.
Greater Transparency: Enhanced accountability measures are being emphasized.
Policy Reviews: The “FMS-Only List” and US Munitions List are under evaluation.
Tracking System: A single electronic tracking system for FMS cases is in development.
Financing Options: Expanded options like CAPS (Capability Acquisition and Production Support) and BLOC (Building Local Opportunities and Capacities) have been introduced.
Legislative Updates: Adjustments to Congressional notification thresholds are being considered.
Executive Direction: The White House has issued statements on reforming foreign defense sales to improve speed and accountability.
Legal Framework
The Arms Export Control Act (AECA) provides the legal foundation for Foreign Military Sales. The full text is available through the House of Representatives website and the Government Publishing Office.
The AECA aims to promote world peace, strengthen US security, enable friendly nations to maintain adequate military capabilities, and reduce international arms trading.
The President officially designates countries eligible for FMS participation. The State Department maintains the United States Munitions List (USML), which specifies defense articles and services subject to export controls.
The Foreign Assistance Act of 1961 provides additional authority for security assistance programs that may use the FMS system. The International Traffic in Arms Regulations (ITAR) implement the AECA’s provisions.
While the United States has signed the Arms Trade Treaty, which establishes global standards for conventional arms trade, it has not ratified this agreement.
Strategic Importance
The FMS program represents a critical tool in American foreign policy. Beyond the immediate economic benefits, these government-to-government sales help build military coalitions, strengthen diplomatic ties, and extend US influence.
For countries facing regional threats, access to American military technology provides both practical security and symbolic alignment with US interests. The resulting partnerships often extend beyond military cooperation into broader political and economic relationships.
As global security challenges evolve, the Foreign Military Sales program will likely remain a cornerstone of US engagement with allies and partners worldwide. The ongoing reform efforts reflect a recognition that in today’s competitive security environment, the effectiveness of this program directly impacts America’s strategic position.
