### Project 664645 — International Cooperative Research & Development

The mission of this program is to establish, sustain, expand, and enhance mutually beneficial international partnerships through the implementation of air, space, and cyber international armament cooperation (IAC) agreements thereby supporting Department of the Air Force (DAF) and Department of War (DoW) goals and objectives. These International Agreements (IAs) will: significantly improve U.S. and allied conventional defense capabilities and capacity; accelerate the availability of defense systems; solve capability gaps; develop, acquire, upgrade, sustain, and/or support interoperable equipment with our allies; create cooperative acquisition, production, or logistic partnerships; promote mutual and equitable sharing of effort, cost, information, and risk; provide access to remote or operational test sites; leverage economies of scale; and promote interoperability with our allies. The DAF is party to more than 349 current air, space, and cyber bilateral and multilateral IAs that leverages $25,300,000.00+ from 46 different partner nations. IAs solve U.S. and allied military capability gaps, develop materiel solutions, harmonize requirements, and build interoperability with our international partners. This program element funds the DAF to identify, develop, process, negotiate, conclude, implement, and manage IAs in compliance with statutory provisions, legal authorities, fiscal constraints, technology transfer controls, intellectual property rights, third party transfer provisions, equitability criteria, industrial base factors, political-military interests, and the National Defense Strategy. Included in this budget are: air, space, and cyber IAC activities; specialized working groups; Air Senior National Representative (ASNR) activities; technology assessments; requirements development; Engineering and Scientist Exchange Program (ESEP); and Administrative and Professional Exchange Program (APEP). This program is in Budget Activity 6, RDT&E Management Support because this budget activity includes research, development, test and evaluation efforts and funds to sustain and/or modernize the installations or operations required for general research, development, test and evaluation.
