Saudi Arabia is one of the largest purchasers of U.S. weapons. Major U.S. systems — combat aircraft, missile-defense systems, precision-guided munitions, naval platforms — are integral to the Saudi military. The Saudi-led coalition's intervention in Yemen, beginning in 2015, drew sustained criticism over civilian casualties from airstrikes, often involving U.S.-supplied munitions.
Congress has repeatedly voted to block or condition Saudi arms sales, often through joint resolutions or amendments tied to defense bills, with several vetoes by the executive branch. The Biden administration suspended sales of "offensive" weapons in 2021 while continuing defensive sales, particularly air and missile defense, which has become especially salient with regional tensions and Houthi missile and drone strikes.
Debates weigh the strategic value of the U.S.-Saudi relationship — including against Iran, in oil markets, and on Israel normalization — against human-rights concerns, conduct in Yemen, and the 2018 murder of journalist Jamal Khashoggi.
