Procurement Profile
DoD is the largest federal buyer, accounting for roughly two-thirds of all federal contract obligations. Major purchases span weapons systems, IT modernization, cybersecurity, logistics, professional services, R&D, and base operations support. The Army, Navy, Air Force, Marine Corps, Space Force, and Defense Logistics Agency operate as semi-autonomous buyers. Most awards run through DoD-specific clauses (DFARS 252.*) and require contractors to meet cybersecurity (CMMC, NIST 800-171), supply chain, and clearance requirements.
