The US State Department and the US Department of Defence (DoD) are legally required to prepare an annual report on arms exports, known as the "Section 655" report. The State Department's contribution is produced by the Directorate of Defense Trade Controls and gives information on goods licensed for export as Direct Commercial Sales (DCS).
The Defense Security Cooperation Agency (DSCA) of the US Department of Defence produces the annual 'Foreign Military Sales, Foreign Military Construction Sales and Military Assistance Facts'. This report contains financial data by fiscal year on FMS agreements, FMS deliveries, foreign military construction sales agreements, foreign military construction sales deliveries, foreign military financing programs, and direct commercial sales deliveries.
The US Department of Defense (DoD) is legally required to prepare an annual report on sales of significant military equipment manufactured in the United States in excess of $2 million, known as the “Section 1231” report. The report covers Foreign Military Sales (FMS) and - when available - Direct Commercial Sales (DCS). It includes descriptions of the goods sold, their financial value, the destination country, the manufacturer of the equipment and the state where the manufacturer is located, broken down by individual contract.
In 2004 the Congressional Research Service began publishing 'U.S. Arms Sales: Agreements with and Deliveries to Major Clients'. This report gives 'background data on United States arms sales agreements with and deliveries to its major purchasers'.
