The Office of the Under Secretary of War for Research and Engineering (OUSW(R&E)) oversees DoW Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) Programs.

These competitive programs are Congressionally-mandated set-asides to encourage domestic small businesses’ engagement in research and development, scientific excellence, and technological innovation through federal research fund investment in critical American priorities to build a strong national economy and accelerate Warfighter capabilities.

OUSW(R&E) serves as the Office of the Secretary of War's point of contact for Congress, the Small Business Administration (SBA), Government Accountability Office (GAO), and the interagency SBIR/STTR community. Our organization also seeks technology partnership opportunities within DoW and with other federal agencies.
