U.S. Department of Defense
Funds Department of Defense, the United States department managing defence science, manufacturing, and technology transition portfolios.
The U.S. Department of Defense (DoD) — operationally renamed 'Department of War' (DoW) under the current administration, though the legal/statutory name remains DoD pending Congressional amendment — is the largest federal funder of defense R&D, advanced manufacturing, and technology transition. Its $841.4 billion national defense budget spans 3.4 million service members and civilians across 4,800 sites in over 160 countries.
For founders and researchers, DoD functions primarily as a policy umbrella: funding authority and programmatic mandates flow downward through service branches (Army, Navy, Air Force, Space Force) and defense agencies (DARPA, DHA, DIU, MDA, NGA, DTRA). Most awards are made by the relevant component, not DoD directly. DoD-direct programs include the government-wide SBIR/STTR umbrella schedule (coordinated via OUSW(R&E)), APFIT (procurement-bridge for small businesses and non-traditional contractors), RISE (transition vehicle under USD(A&S)), and OSD ManTech (advanced manufacturing coordinated through Manufacturing Innovation Institutes).
Priority technology areas as of 2026 include applied AI and autonomy, microelectronics, advanced manufacturing, quantum science, directed energy, hypersonics, biotechnology, and contested logistics.
