The Coalition Warfare Program (CWP) supports the Department's initiatives to increase burden sharing, strengthen alliances and enhance interoperability, support the defense industrial base and technological advantage, and maintain focus on warfighter needs. This program supports Department of War (DoW) organizations that work with foreign partners to collaboratively address strategic technology gaps for current and future missions, develop interoperability solutions for coalition operations, and develop and strengthen defense relationships. The CWP provides a broad base of technological, operational, and logistical support for military operations and eases the United States (U.S.) financial and manpower burdens associated with meeting military goals and objectives. Coalitions and relationships with international partners are high priorities for the nation and the DoW. The CWP supplements U.S. Government proponents' funding for cooperative efforts, ensuring U.S. funds are sufficient to complete research and development activities with foreign partners. When CWP funds are used to help fund a cooperative project, that project leverages technical and financial contributions of the foreign partners and accelerates the development and delivery of technical solutions to the warfighter. For every $1 the CWP has invested in cooperative projects with 86 partners since 2001, the program has leveraged $3 in foreign partner resources and $2 in other U.S. Government resources. The CWP funding enables the DoW project teams to transition technology to operational use, further development, or integration into other systems. These projects may also form the basis for future cooperation with international partners.

Program detail

Mission & acquisition strategy

The Coalition Warfare Program (CWP) supports the Department's initiatives to increase burden sharing, strengthen alliances and enhance interoperability, support the defense industrial base and technological advantage, and maintain focus on warfighter needs. This program supports Department of War (DoW) organizations that work with foreign partners to collaboratively address strategic technology gaps for current and future missions, develop interoperability solutions for coalition operations, and develop and strengthen defense relationships.

The Combatant Commands, Services, Defense Agencies, and the Office of the Secretary of War nominate candidate projects on an annual basis. CWP provides selected projects up to three years of incremental funding. The Program selects projects that address DoW priorities and meet the needs and requirements specified by the Joint Staff and the Combatant Commanders. Projects have equitable contributions from international partners, strong potential for transition, Combatant Command endorsement, and contribute to allied interoperability and/or meet a warfighter need.
