Iran’s aerial drone program has become an area of increasing concern to the United States and its partners, particularly in light of Iran’s direct transfers to Russia and illicit shipments to proxy groups such as the Houthis in Yemen.

The Wisconsin Project on Nuclear Arms Control convened an expert panel for a private roundtable discussion on how sanctions and export controls can inhibit Iran’s development of unmanned aerial vehicles. The panel offered recommendations of how supply-side controls, despite some inherent limitations, can be strengthened and can continue to limit the size and capability of Iran’s drone arsenal in the future.
