Opportunity Information: Apply for DFOP0018232

This Notice of Funding Opportunity (DFOP0018232) comes from the U.S. Department of State, Bureau of Arms Control and Nonproliferation, through the Office of the Nonproliferation and Disarmament Fund (ACN/NDF). It seeks one U.S.-based nonprofit partner to provide event management support for the 2027 Multilateral Action on Sensitive Technologies (MAST) Plenary, which is planned to be hosted at the Harry S. Truman Building in Washington, D.C. The award will be made as a cooperative agreement, meaning the selected organization should expect close coordination with relevant State Department offices rather than operating fully independently.

The purpose of the funding is practical and operational: to plan, coordinate, and execute multiple events associated with the 2027 MAST Plenary. MAST is described as a multilateral coordinating forum among key foreign partner countries that produce and supply sensitive technologies. The forum focuses on developing tools, procedures, and coordinated approaches to safeguard sensitive technologies that could enable weapons of mass destruction (WMD) capabilities. In other words, the plenary and associated working-level engagements are meant to reduce the risk that weapons-applicable goods, materials, and know-how are diverted, exploited, or misused by hostile actors. The NOFO emphasizes that this risk reduction is supported through measures such as better data collection and information integration, development of response options, and coordinated multilateral execution across participating countries.

A central feature of MAST is that it is not limited to a single annual meeting. Between plenary sessions, working groups are used to keep communication regularized among partners and to examine specific technology-related issues in more depth. While the NOFO is focused on the 2027 plenary events themselves, the reference to working groups signals that the overall MAST structure involves recurring coordination, multiple sessions, and issue-focused discussions that can require careful logistical orchestration and stakeholder management.

Eligibility is limited to U.S.-based nonprofit/non-governmental organizations. Both 501(c)(3) nonprofits (other than institutions of higher education) and non-501(c)(3) nonprofits (also other than institutions of higher education) are eligible to apply. The opportunity is categorized as discretionary funding, and it falls under the funding activity category of Science and Technology and other Research and Development, with CFDA number 19.224.

Financially, the opportunity anticipates a single award with an expected maximum (award ceiling) of $175,000. The NOFO lists an original application closing date of July 1, 2026, and indicates it was created on May 1, 2026. Overall, the grant is aimed at securing an experienced nonprofit partner that can reliably handle high-profile, multi-event plenary support in a sensitive national security policy area, ensuring the State Department can convene international partners effectively to strengthen shared safeguards against the proliferation and diversion of sensitive, WMD-relevant technologies.
