Contract Types

Five primary acquisition pathways for AI and autonomous systems procurement. Each carries distinct timelines, regulatory burden, and strategic fit.

Traditional
FAR / DFARS

Full and open competition governed by the Federal Acquisition Regulation and Defense FAR Supplement. Maximum oversight, broad competition, and mandatory cost/pricing data above simplified acquisition thresholds.

Timeline: 18 — 36 months
Value: Uncapped
Preferred for AI
OTA — Other Transaction Authority

Bypasses FAR/DFARS for prototype and follow-on production agreements. Faster award, fewer audit rights, and flexible IP terms make OTA the dominant vehicle for AI and autonomous systems. Requires nontraditional defense contractor participation or cost-sharing.

Timeline: 3 — 9 months
Value: Uncapped (prototype / production)
Small Business
SBIR / STTR

America's primary small business R&D funding mechanism. Phase I validates feasibility; Phase II develops the prototype; Phase III commercializes with no statutory dollar cap and can transition directly to production OTA or prime contracts.

Phase I: $50K — $250K
Phase II: $500K — $1.5M
Phase III: Unlimited
Commercial Bridge
DIU Commercial Solutions Opening

The Defense Innovation Unit's rapid acquisition tool bridges mature commercial technology directly to military use. CSO awards are typically OTA-based, require working prototypes, and are evaluated by military end-users, not contracting officers.

Timeline: 2 — 6 months
Value: $1M — $50M typical
R&D
DARPA BAA — Broad Agency Announcement

Solicitations for high-risk, high-reward basic and applied research. Evaluated on scientific and technical merit rather than price. Multiple award structure typical. Not appropriate for near-term production-ready systems.

Timeline: 6 — 18 months (to award)
Value: $1M — $100M+

How to Bid

The administrative and strategic prerequisites before you can compete for a single dollar of defense AI funding.

Step 01 — Registration

SAM.gov, CAGE Code & NAICS

  • System for Award Management (SAM.gov) registration is mandatory for all federal contracts — renew annually
  • CAGE code (Commercial and Government Entity) is auto-assigned upon SAM registration; required for invoicing
  • Select NAICS codes carefully: 541715 (R&D in physical sciences), 541512 (computer systems design), 541330 (engineering services) are common for AI/defense
  • UEI (Unique Entity Identifier) replaced DUNS in 2022 — verify yours in SAM.gov before any solicitation response
Step 02 — Positioning

Capability Statement

  • One-page document — contracting officers read hundreds; brevity is competitive advantage
  • Core competencies: 4-6 specific technical capabilities tied to NAICS codes
  • Past performance: contract numbers, agency, dollar value, period, POC — even if small
  • Differentiators: patents, clearances, certifications (ISO 9001, CMMC), unique datasets
  • Contact block: CAGE, UEI, SAM expiration date, DUNS, socioeconomic status (WOSB, SDVOSB, 8(a), HUBZone)
Step 03 — Past Performance

Building a Record from Zero

  • Start with subcontracting: large primes are required to subcontract to small businesses under certain thresholds
  • GSA Schedule 70 (IT) provides a low-barrier vehicle for initial task orders and past performance
  • State and local government contracts count — document them with federal-equivalent detail
  • SBIR Phase I completions are recognized past performance for follow-on Phase II and III awards
  • University or nonprofit collaborative R&D agreements can be cited as relevant experience
Step 04 — Access

Security Clearances

Secret
6 — 12 months typical. Requires U.S. citizenship, background investigation, no disqualifying foreign contacts. Company must have Facility Clearance (FCL). Cost: $0 to applicant; sponsor (government) pays.
Top Secret
12 — 24 months. Full-scope background investigation (SSBI). Psychological evaluation possible. Required for most classified AI programs.
TS/SCI
18 — 36 months. Access to Sensitive Compartmented Information. Polygraph (CI or Full-Scope) required for NSA, CIA, DIA programs. Mandatory for signals intelligence and targeting AI.
Step 05 — Strategy

Teaming Arrangements

  • Teaming Agreements (TA): non-binding intent to partner; executed before RFP release
  • Subcontracting: prime holds contract, subs execute work under flow-down clauses
  • Joint Ventures: formal business entity; both parties share liability, profits, and past performance
  • Mentor-Protege Program: large prime invests in small business development; DoD subsidizes the relationship
  • OTA consortia (NSTXL, SOSSEC, NCMS) allow rapid teaming without full JV overhead

Key Acquisition Programs

The eight highest-value or highest-velocity programs for AI and autonomous systems vendors in 2025-2026.

OSD Priority
Replicator Initiative

DoD's flagship program to field thousands of attritable autonomous systems within 18-24 months. Prioritizes low-cost, mass-producible UxS across all domains. OTA is the primary vehicle. Moves at acquisition speed unprecedented for a Secretary-level initiative.

Navy
NavalX

Department of the Navy's tech bridge network connecting Fleet operators to commercial innovators via Agility Offices at major naval installations. Facilitates prototype agreements, Fleet experimentation, and transition to NAVAIR/NAVSEA programs of record.

Lead: DON / NavalX
DARPA
DARPA

Defense Advanced Research Projects Agency funds high-risk, high-reward research 10-20 years from fielding. AI programs include ACE (air combat), GARD (adversarial robustness), Lifelong Learning Machines. BAA is the standard solicitation vehicle. Program Managers have significant discretionary authority.

Annual R&D Budget: ~$4B

Startup and Investor Pathways

Tailored guidance for early-stage companies entering defense markets and the investors backing them.

For Startups

Entry Vectors
  • DIU CSO Pathway Fastest route from commercial product to military contract. DIU awards typically close in 60-90 days. Requires a working prototype and demonstrated military relevance. No CAGE code required to apply; required before award.
  • AFWERX / SpaceWERX / NavalX Innovation Hubs Service-specific accelerators with direct SBIR award authority. No intermediary required. Regular open topic cycles; operators evaluate proposals. Strong transition pipeline to programs of record.
  • In-Q-Tel CIA's strategic venture arm invests in dual-use technology companies. Provides capital, U.S. Intelligence Community access, and contract introductions. IQT investment is a strong credentialing signal for subsequent DoD engagement. Not a grant — equity investment.
  • Hacking for Defense (H4D) Stanford-originated university program embedding student teams on classified problem sets. Produces alumni networks with cleared contacts inside agencies. H4D participants frequently spin out as defense-native startups with existing government relationships.
  • NSIC — National Security Innovation Capital DoD-funded patient capital for dual-use hardware companies that struggle with typical VC timelines. Focuses on manufacturing readiness and supply chain resilience for national security-critical technologies.
  • Defense-Focused Investors Shield Capital (cyber/AI), Lux Capital (deep tech), and a16z's American Dynamism portfolio are the leading institutional VCs with active defense theses. Each has government relationship networks and can accelerate contract introductions alongside capital.

For Investors

Due Diligence Lexicon
Cost-Plus vs. Fixed-Price vs. T&M Cost-Plus reimburses all allowable costs plus a fee; lowest financial risk to contractor, highest to government. Fixed-Price transfers performance risk to contractor; higher margin potential but exposure on overruns. Time-and-Materials bills labor hours at agreed rates plus material costs; used when scope is uncertain.
IDIQ vs. Single-Award vs. MAC Indefinite Delivery/Indefinite Quantity contracts establish a ceiling and vehicle; task orders compete for funded work. Single-Award IDIQ grants exclusive vehicle to one awardee. Multiple Award Contract (MAC) places several vendors on a vehicle, then requires competition at the task-order level.
Contract Ceiling vs. Funded Value The contract ceiling is the maximum potential value if all options are exercised. Funded value is actual obligated dollars — the only number that produces revenue. A $500M IDIQ with $2M funded is a $2M contract. Evaluate funded value, not ceiling, for financial modeling.
Period of Performance + Option Years The base period is contractually obligated performance time. Option years are government's unilateral right to extend at pre-negotiated prices. Options provide revenue visibility but are not guaranteed. Model option exercise probability (70-85% for incumbent performers) when projecting ARR.
Reading Contract Announcements USASpending.gov and SAM.gov award notices disclose contractor name, award amount, place of performance, NAICS, and contracting office. FPDS-NG provides historical contract data for competitive intelligence. Parse CLIN structure in posted contracts to identify recurring software/service revenue versus one-time hardware.

Getting Started Checklist

Ten sequential steps from zero to first proposal submission. Complete in order — skipping administrative prerequisites disqualifies even the strongest technical proposal.

  1. Register on SAM.gov
    Create a login.gov account, then complete the full SAM.gov entity registration. Requires legal business name, EIN/TIN, physical address, and banking information for EFT payments. Processing takes 5-10 business days. Set a calendar reminder to renew annually — lapses immediately disqualify you from awards.
  2. Obtain Your CAGE Code and UEI
    Your Commercial and Government Entity code and Unique Entity Identifier are auto-generated upon SAM registration. Record both — every contract, invoice, and proposal submission requires them. CAGE code is also required for security clearance facility applications.
  3. Select and Verify NAICS Codes
    Identify 2-4 NAICS codes that accurately describe your primary offerings. Your small business size status (and therefore SBIR/set-aside eligibility) is determined by the NAICS code on each specific solicitation — size limits vary by code. Cross-reference the SBA size standards table before every opportunity.
  4. Determine Socioeconomic Certifications
    Identify applicable small business designations: Woman-Owned Small Business (WOSB), Service-Disabled Veteran-Owned Small Business (SDVOSB), 8(a) Business Development Program, or HUBZone. Each opens set-aside competitions with dramatically reduced competition. 8(a) certification provides 9 years of no-competition award eligibility.
  5. Draft Your Capability Statement
    One page maximum. Core competencies, past performance (with contract numbers), differentiators, company data (CAGE, UEI, NAICS, socioeconomic status, SAM expiration). Design it professionally — contracting officers and program managers will assess company maturity from this document before agreeing to any meeting.
  6. Set Up SAM.gov and Beta.SAM Opportunity Alerts
    Configure NAICS-based opportunity alerts in SAM.gov. Subscribe to agency-specific listservs (DARPA BAA alerts, DIU CSO announcements, AFWERX topic releases). Monitor USASpending.gov for awarded contracts in your capability area to identify incumbent relationships and competition landscape.
  7. Engage an OTA Consortium
    Join at least one OTA consortium (NSTXL, SOSSEC, NCMS, or AFWERX Open Topics consortium). Consortium membership enables participation in OTA prototype agreements without individual agency relationships. Many DoD AI solicitations are executed exclusively through consortium vehicles invisible to non-members.
  8. Initiate CMMC Compliance Assessment
    Cybersecurity Maturity Model Certification (CMMC) is now required for all DoD contracts involving Controlled Unclassified Information (CUI). Level 1 (basic cyber hygiene) is self-assessed. Level 2 requires third-party assessment. Most AI contracts involving operational data will require CMMC Level 2 or higher. Begin gap assessment immediately — remediation takes 6-18 months.
  9. Build Government Relationships Before Solicitations Drop
    Attend industry days, AUSA, DSEI, and program-specific conferences. Request informational meetings with Program Executive Offices and contracting officers during pre-solicitation phases — this is legal and expected. Relationships formed during market research translate directly into solicitation requirements that favor your capabilities. Submit Sources Sought responses to establish visibility.
  10. Submit Your First Proposal
    Target an SBIR Phase I or DIU CSO as your first submission — lower word counts, faster cycle, and evaluators accustomed to early-stage technology. Allocate 6-8 weeks for a quality proposal. Respond to every section requirement explicitly. Win or lose, request a debrief — the feedback is legally required and invaluable for subsequent submissions.
