How to Sell to the Department of Defense
The Department of Defense is the single largest buyer in the federal government, spending over $400 billion annually on contracts for everything from weapon systems and IT services to food, fuel, and office supplies. Selling to DoD offers enormous opportunity but requires navigating unique regulations, security requirements, and procurement processes.

DoD Procurement Overview
DoD procurement is governed by the same Federal Acquisition Regulation (FAR) that applies to all federal agencies, plus the Defense Federal Acquisition Regulation Supplement (DFARS), which adds defense-specific requirements. This dual regulatory framework creates additional compliance obligations that contractors must understand before pursuing DoD work.
The sheer scale of DoD buying creates a decentralized procurement environment. Each military service (Army, Navy, Air Force, Marines, Space Force) has its own contracting organizations, and defense agencies like DLA, DISA, and MDA operate independently. Understanding which organization buys what you sell is critical for effective business development.
DoD uses the full range of contract types, from simple purchase orders for commercial items to complex cost-reimbursement contracts for major weapon systems. For new entrants, commercial item procurements (FAR Part 12) and simplified acquisitions under the micro-purchase and simplified acquisition thresholds are the most accessible entry points.
Registration in SAM.gov is mandatory, and most DoD contracts above $30,000 require CAGE (Commercial and Government Entity) codes. If you will handle Controlled Unclassified Information (CUI), you will also need to comply with NIST 800-171 cybersecurity requirements and, increasingly, the Cybersecurity Maturity Model Certification (CMMC).
Key DoD Buying Commands
Each military service and defense agency has specialized contracting organizations. Knowing which command buys your products or services focuses your business development.
Army Contracting Command (ACC)
Headquartered at Redstone Arsenal, AL. Manages Army acquisitions including IT, services, logistics, and weapon systems. Key subordinate organizations include ACC-Aberdeen Proving Ground, ACC-Rock Island, and Mission and Installation Contracting Command (MICC).
Naval Supply Systems Command (NAVSUP)
Manages Navy and Marine Corps supply chain and contracting. Fleet Logistics Centers (FLCs) handle regional procurement. NAVSUP Weapon Systems Support handles spare parts and repair services. Naval Sea Systems Command (NAVSEA) handles shipbuilding.
Air Force Life Cycle Management Center (AFLCMC)
At Wright-Patterson AFB, OH. Manages Air Force acquisitions across weapon systems, IT, and services. Air Force Installation Contracting Center (AFICC) handles base-level services. Air Force Materiel Command (AFMC) oversees sustainment.
Defense Logistics Agency (DLA)
The largest DoD buyer of commercial products. Manages global supply chains for fuel, food, medical supplies, construction materials, uniforms, and spare parts. Over $40 billion in annual purchases. Primarily uses long-term contracts and blanket purchase agreements.
Defense Information Systems Agency (DISA)
Provides IT and communications infrastructure for DoD. Major buyer of cloud services, cybersecurity, networking, and enterprise IT. Manages milCloud and the DoD Information Network (DoDIN). A key customer for IT contractors.
Other Key Organizations
Missile Defense Agency (MDA), Defense Health Agency (DHA), Defense Contract Management Agency (DCMA), U.S. Special Operations Command (SOCOM), U.S. Cyber Command (CYBERCOM), and Space Force acquisitions through Space Systems Command (SSC).
CMMC Requirements
The Cybersecurity Maturity Model Certification (CMMC) is DoD's framework for ensuring that defense contractors adequately protect Controlled Unclassified Information (CUI) and Federal Contract Information (FCI). CMMC is being phased into DoD contracts and will eventually be required for all contractors handling sensitive information.
CMMC 2.0 has three levels: Level 1 (Foundational, 17 practices, self-assessment), Level 2 (Advanced, 110 practices aligned with NIST 800-171, third-party assessment for critical programs), and Level 3 (Expert, NIST 800-172 practices, government-led assessment). Most contractors handling CUI will need Level 2 certification.
The certification process involves a readiness assessment, remediation of any gaps, and formal assessment by a Certified Third-Party Assessment Organization (C3PAO). Timelines vary but typically take 6 to 18 months from initial assessment to certification. Contractors should begin the process well before CMMC appears in their target solicitations. See our CMMC guide for detailed preparation steps.
Security Clearance Considerations
Many DoD contracts require personnel security clearances (Confidential, Secret, or Top Secret) and/or facility security clearances (FCL). A facility clearance allows your company to store and work with classified information at your facilities and is a prerequisite for your employees to obtain individual clearances.
Obtaining an FCL requires sponsorship by a government contracting activity (GCA) or a cleared contractor with a legitimate classified subcontracting need. You cannot self-sponsor a clearance. The Defense Counterintelligence and Security Agency (DCSA) processes clearance requests, and timelines range from several months to over a year depending on the level and investigation backlog.
For contractors new to classified work, teaming with an established cleared contractor is often the fastest path to gaining access. As the prime contractor's subcontractor, you can obtain clearance sponsorship through the subcontract. Over time, you can build the cleared workforce and facility infrastructure needed to pursue prime contracts independently. See our security clearances guide for more details.
Key DFARS Clauses for DoD Contractors
DFARS 252.204-7012 — Safeguarding CUI
Requires contractors to implement NIST 800-171 security controls for protecting CUI, report cyber incidents within 72 hours, and provide media and access for forensic analysis. This clause is the foundation for CMMC requirements.
DFARS 252.225-7001 — Buy American and Balance of Payments
DoD has stricter domestic sourcing requirements than civilian agencies. Products must be mined, produced, or manufactured in the United States, with limited exceptions. Non-compliant products require waivers that are increasingly difficult to obtain.
DFARS 252.227-7013/7014 — Data Rights
Governs intellectual property and data rights in DoD contracts. Understanding the distinction between unlimited rights, government purpose rights, and limited/restricted rights is critical for firms with proprietary technology. These clauses can significantly impact your competitive position and the value of your IP.
DFARS 252.244-7001 — Subcontracting Requirements
Imposes consent requirements for subcontracting and flows down DFARS clauses to subcontractors. Prime contractors must ensure subcontractors comply with applicable DFARS requirements including cybersecurity, sourcing, and reporting.
Small Business Programs at DoD
DoD is the largest federal buyer from small businesses, awarding over $80 billion annually to small firms. Each military service and defense agency has an Office of Small Business Programs (OSBP) that advocates for small business participation and sets subcontracting goals.
Key small business programs at DoD include the Mentor-Protégé Program (which pairs large defense contractors with small businesses for capacity building), the Small Business Innovation Research (SBIR) program (DoD has the largest SBIR budget), and the Procurement Technical Assistance Centers (PTACs) which provide free counseling to businesses seeking government contracts.
DoD actively sets aside contracts for small businesses, 8(a) firms, HUBZone businesses, service-disabled veteran-owned small businesses, and women-owned small businesses. The simplified acquisition threshold ($250,000) is automatically reserved for small businesses unless the contracting officer determines insufficient competition exists.
The DoD Rapid Innovation Fund (RIF) and other programs specifically target innovative small businesses that can bring new technologies to defense applications. These programs often provide non-dilutive funding and can serve as a bridge to larger production contracts.
