Foreign Military Sales (FMS)

Definition

Foreign Military Sales (FMS) is a U.S. government program for the government-to-government sale of defense articles, services, and training to eligible foreign governments and international organizations. Administered primarily by DSCA within DoW, FMS is executed through Letters of Offer and Acceptance (LOAs) with the foreign purchaser. DoW contracts with U.S. industry on behalf of the foreign customer and adds a small administrative surcharge. FMS is distinct from Direct Commercial Sales (DCS), where the contractor sells directly to a foreign government under State Department licenses.

Why It Matters

FMS is a multi-billion-dollar annual market. U.S. contractors who support FMS programs benefit from DoW-managed contract vehicles, reduced export-compliance risk, and a highly visible alignment with U.S. foreign policy priorities. Understanding the FMS lifecycle (LOR → PA → LOA → Case Execution → Case Closure) and DSCA's role opens access to work in major regional partner nations.

Example

A U.S. missile manufacturer's FMS case to a NATO ally generates $120M in production contracts via the Army's AMCOM command, executed under an existing FMS-funded DoW contract rather than a DCS arrangement.
