Selling to the Department of Defense
The Department of Defense is by a wide margin the largest buyer in the federal government, awarding more contract dollars than all civilian agencies combined. Its buying is decentralized across the Army, Navy, Air Force, Marine Corps, Space Force, and the defense agencies (DLA, DISA, DARPA, MDA), each with its own contracting commands and priorities.
What DoD buys
- Weapon systems, platforms, and sustainment
- IT modernization, cyber, and C4ISR
- Base operations, facilities, and logistics support
- Professional and engineering services
- Research and development
Common NAICS codes on DoD solicitations
Small-business notes
DoD has the largest small-business goal in dollar terms and runs an extensive set-aside program. Subcontracting to a prime is often the realistic entry path — most large DoD contracts carry mandatory small-business subcontracting plans. Nearly every DoD component has its own Office of Small Business Programs.
