Department of Defense

About Department of Defense

The Department of Defense is the single largest federal contracting organization in the United States, awarding more than $400 billion annually across the Army, Navy, Air Force, Marine Corps, Space Force, and the Fourth-Estate defense agencies such as the Defense Logistics Agency and the Defense Information Systems Agency. DoD solicitations cover the full breadth of federal procurement — from Major Defense Acquisition Programs (MDAPs) and multi-decade platform procurements, to facilities operations, IT modernization, research and development, professional services, supply-chain logistics, and complex classified procurement. The most common NAICS codes seen on DoD RFPs include 541512 (Computer Systems Design), 541330 (Engineering Services), 541715 (R&D in the Physical Sciences), 561210 (Facilities Support), 488510 (Freight Transportation Arrangement), and 332312 (Fabricated Structural Metal Manufacturing). Set-aside behavior is heavily weighted toward small business: the Department runs a robust 8(a) pipeline, HUBZone set-asides at major installations, SDVOSB set-asides through the VA referral pipeline, and WOSB awards across service components. Evaluation typically leans hard on relevant past performance, security clearance posture, and demonstrated cost/schedule control on prior defense programs.
