Every major US arms transfer abroad travels one of two roads: the Foreign Military Sales system, where the US government is the contracting party, or direct commercial sales, where a US company holds an export license and contracts with the foreign customer itself. Per DSCA's fiscal 2024 announcement, FMS agreements reached $117.1 billion in value, and per State Department annual reporting, direct commercial authorizations routinely add tens of billions more in possible sales. Choosing between the paths shapes pricing, speed, lifecycle support and political oversight for the life of the weapon system.

How does the government-to-government path work?
In an FMS case, the partner government requests equipment through its embassy, the Defense Security Cooperation Agency coordinates the response with the military departments, and the deal is formalized in a Letter of Offer and Acceptance signed by both governments. The US government buys the hardware from industry under its own acquisition rules, then sells it to the partner at cost plus a administrative surcharge, which per DSCA published rates is generally around 3.5 percent for most cases. The partner gets the weight of the US government behind pricing, quality assurance, security assistance officers and end-use monitoring under the Arms Export Control Act.
The same structure creates the FMS complaints industry buyers know well. Industry does not negotiate directly with the foreign customer during the case; requirements pass through government channels, which adds months. Per DSCA's own modernization initiatives, case processing timelines have been a persistent reform target, and 2020s policy guidance directed faster review of major cases as allied demand surged after 2022.
How does the direct commercial path work?
In a direct commercial sale, the US company negotiates price, delivery and support directly with the foreign buyer, then obtains authorization from the State Department's Directorate of Defense Trade Controls for items on the United States Munitions List, or from the Commerce Department for items on the Commerce Control List. Licenses carry conditions: end-use and retransfer restrictions, sometimes embedded voluntary DoD assessments, and reporting duties. Per DDTC published processing statistics, standard license applications have historically been adjudicated within about 30 to 45 days, which for many categories beats the FMS case cycle.
The company owns the compliance burden in exchange for the direct relationship. Industry handles marketing, offsets negotiation, warranty terms and sustainment contracts on commercial terms, and answers to the licensing agency for every deviation. A violation exposes the company, not the government, to civil penalties, and per State Department enforcement notices, settlements in recent years have reached into the tens and hundreds of millions of dollars for major contractors.
Which products fit which channel?
The channels sort by system complexity and political sensitivity. Fighters, missile systems, major naval vessels and anything with sensitive technology overwhelmingly move through FMS, because the US government wants visibility into fielding, training and security. Per DSCA case records, the largest recent agreements — F-35 program partnerships, Patriot system sales, multi-billion-dollar aircraft cases — are all government-to-government. Direct commercial sales dominate in munitions components, software, training services, parts support, armored vehicles in some configurations and law-enforcement equipment.
- FMS: major platforms, classified technology, cases needing end-use monitoring
- DCS: services, components, upgrades, commercial derivative equipment
- Hybrid: government sells the platform, industry sells sustainment commercially

What does the customer actually experience?
From the buyer's chair, FMS means predictable but inflexible. Pricing is set by the US cost structure rather than negotiation, delivery schedules ride on US program health, and the buyer cannot easily shop modifications. Per GAO reviews of FMS case performance, schedule slips on major cases have been common enough that GAO has recommended better tracking, and buyers factor that risk into planning. What they get in return is assurance: the US government commits to the relationship, and spares, training and upgrades follow through the same pipeline.
Direct commercial sales mean speed and negotiating room, with the buyer taking on more risk. The company sets the terms, but the buyer must vet the supplier's license coverage, accept that government-to-government guarantees do not exist, and manage security obligations that in an FMS case would be handled by US personnel. NATO allies buying commercial software or precision munitions stockpiles often choose DCS precisely because procurement can move in a single budget year.
Sustainment is where the choice compounds. An FMS platform enters a support pipeline of case-managed spares, US-government-facilitated training and follow-on upgrades that can run for decades, and per DSCA case records, sustainment and support cases are a majority of the thousands of open cases on the books. A commercial system depends on the manufacturer's product support contracts, which can be renegotiated on market terms but offer no government backstop if the supplier exits the line. Buyers now write that dependency into their channel decisions at the initial acquisition, not years later.
Pricing transparency differs too. FMS pricing follows US government cost principles, and per DSCA published financial management guidance, partners can request cost breakdowns for their own cases. Commercial contracts price to market, and the buyer's leverage depends on competition and volume commitments rather than cost accounting. For munitions and components, that has made large multi-year commercial orders a favored tool for allies trying to lock industrial capacity during the current production surge.
How does oversight differ between the channels?
Both channels end at Congress, but the mechanics differ. FMS cases are formally notified under the Arms Export Control Act once value crosses statutory thresholds, and the notifications appear in DSCA's public database. Direct commercial sales require licenses rather than individual congressional notification in most cases, though the State Department reports aggregates to Congress annually and major defense articles draw case-by-case review in practice. Per State Department annual Section 655 reporting, the volumes of licensed direct commercial activity are tracked, but individual deals lack the public paper trail an FMS notification leaves.
What has recent policy changed?
The balance between the channels is a standing policy argument. After 2022, executive-branch reviews of arms transfer policy directed faster case processing and expanded use of direct commercial pathways where security monitoring needs were lower, and per State Department announcements the agency modernized ITAR licensing with expanded license exemptions for close allies. Industry groups, including the largest aerospace and defense trade associations, have published recommendations arguing that the FMS pipeline cannot be the default for every munitions order if production lines are to absorb surge demand. The government position, per DSCA statements, is that FMS remains the channel of choice for major systems because it preserves end-use monitoring and regional security architecture.
Buyers hedge between the channels. Several NATO members run parallel programs, fielding US platforms through FMS while stockpiling munitions through commercial licenses, then argue over which channel gets credit in burden-sharing accounting. Per DSCA and NATO public reporting, alliance commitments count both channels toward capability pledges, which reduces but does not eliminate the friction.
Why does the split matter for industrial planning?
Producers watch the channel because it shapes demand signals. An FMS agreement for 50 aircraft generates a production-planning line item inside a US program of record; a commercial license for 500 precision-guided munitions generates a private backlog the company must finance. Per DSCA fiscal 2024 data, the surge in FMS agreements also pulled industrial base capacity toward government cases, and industry associations have argued that licensing reform for commercial sales is part of the capacity answer. For any supplier of defense articles, the channel decision is not just a legal classification — it determines who bears financing risk, who owns the customer relationship, and whose paperwork defines the program for the next thirty years.
