Product Development

The Rapid Prototyping Program (RPP) develops prototypes to deliver capabilities, inform requirements, and bridge the gap between RDT&E activities and fieldable solutions. RPP facilitates and accelerates joint, cross-cutting prototyping efforts within the Services and Defense Agencies. This program has the agility to select, fund, and implement projects in the year of execution as new opportunities or threats emerge. In consultation with the Service Science and Technology (S&T) executives, selected projects generally receive a single year of funding to accelerate capability transition to Services’ and Agencies’ programs of record. Projects deemed critical by the Under Secretary of War for Research and Engineering (USW(R&E)), the Joint Staff, and the Combatant Commands receive higher amounts of funding across multiple years. Planned funding supports the Joint Warfighting Concept (JWC), the Office of the Under Secretary of War for Research and Engineering's (OUSW(R&E)) critical technology areas, and Service and Agency needs to enable rapid response to emergent and time-sensitive threats.

Program detail

Mission & acquisition strategy

The Rapid Prototyping Program (RPP) supports the Department's initiatives to Defend the Homeland, Build Sustainable and Long-Term Advantage, and Build a Resilient Joint Force and Defense Ecosystem. RPP supports the rapid development of prototypes within 12-to-24 months to address joint urgent and emergent needs identified through ideation with the Joint Staff, Combatant Commands, or Secretary of War guidance. Prototype requirements are developed using threat-informed physics-based mission analyses and are evaluated under the Office of the Assistant Secretary of War for Mission Capabilities’ (OASW(MC)) campaign of experimentation, resulting in military utility assessments.

RPP leverages the Services’ and Defense Agencies' most efficient and effective acquisition approaches for rapid prototyping. This includes using Other Transaction Authorities and new or existing contract vehicles.
