What the grant funds
The Department of State’s Office of the Nonproliferation and Disarmament Fund (ACN/NDF) is pleased to announce an open competition for assistance awards through this Notice of Funding Opportunity (NOFO). ACN/NDF invites U.S.-based non-profit/non-governmental organizations to submit proposals for projects that will advance the mission of NDF’s event management project for the 2027 Multilateral Action on Sensitive Technologies (MAST) Plenary. MAST provides a coordinating forum for key foreign countries, which are producers and suppliers of sensitive technologies, to develop the tools and procedures needed to safeguard sensitive technologies possessing weapons of mass destruction (WMD) and enable capabilities from foreign diversion, exploitation, and potential misuse. These activities will reduce the potential for diversion of weapons-applicable sensitive goods and technologies, including through integration of data collection, development of response options, and coordinated multilateral execution. Working groups operate to regularize communication among the partners between plenary sessions and examine technology-related issues in greater detail. The successful applicant will support appropriate State Department offices with the planning, logistics, and execution of multiple events during the 2027 MAST Plenary hosted at the Harry S. Truman Building.
