Major Arms Sales (via FMS) Notification Tracker
With State Department blessing, the Defense Security Cooperation Agency notifies Congress of major arms sales under the Foreign Military Sales (FMS) program, starting a clock (typically 30 days) during which Congress can block a sale by passing a resolution to do so in both the House and Senate. While certain terms of agreements may change and deliveries (if any) take years to complete, these notifications serve as important public moments to understand and debate, where appropriate, future U.S. arms transfers (equipment and services).*

* Because Congressional leaders are informally consulted before public notification occurs, significant Congressional opposition to notified sales is very rare, although importantly did occur in 2016 regarding tanks to Saudi Arabia, and again in 2017 regarding PGMs to Saudi Arabia. Up until time of delivery, Congress or the President can block or alter a sale. (See CRS report.)
This page only looks at major arms sales notified here because these tend to be the largest and most visible of eventual U.S. arms transfers. However, U.S. arms sales and other transfers occur through a variety of programs, including some led through the Commerce Department. The Security Assistance Monitor is an excellent resource for data and information on the broad range of U.S. arms and security assistance.
