The Arms Control, Verification and Compliance (AVC) Bureau’s core mission is to ensure that appropriate verification requirements and capabilities are fully considered and properly integrated throughout the development, negotiation, and implementation of arms control, nonproliferation, and disarmament agreements and commitments, and to ensure that other countries’ compliance is carefully watched, rigorously assessed, appropriately reported, and resolutely enforced. The bureau leads U.S. efforts to develop arms control policies for the implementation of existing agreements and the negotiation of future agreements. AVC prepares the President’s annual report to Congress on Adherence to and Compliance with Arms Control, Nonproliferation, and Disarmament Agreements and Commitments. AVC has the lead within the Department of State on all issues related to missile defense and national security space policy. It also leads efforts to develop new verification and transparency technologies in support of arms control agreements and arrangements. AVC offices include:
