The FY2026 NDAA Authorized $900B+ in Defense Spending. Here's What Changed for Small Contractors.

President Trump signed the FY2026 National Defense Authorization Act on December 18, 2025. It authorizes over $900 billion for the Department of Defense and national security programs -- roughly $8 billion above the administration's original request. With final appropriations landing at $866.6 billion for the base budget, this is the largest defense authorization in U.S. history.

The headline number matters. But for small defense contractors, the real story is buried in the acquisition reform provisions. This NDAA fundamentally changes how DoD buys things, who it buys from, and how much paperwork is involved. Most of those changes favor smaller companies.

Here's what you need to know.

The Compliance Burden Just Got Lighter

This is the single biggest change for small and mid-market contractors. The NDAA raised several cost thresholds that determine when federal accounting and pricing rules kick in:

• Cost or pricing data threshold: Increased from $2.5 million to $10 million. If your contracts fall below this, you no longer need to submit certified cost or pricing data -- a process that historically requires significant accounting infrastructure and DCAA audit readiness.
• CAS applicability threshold: Increased from $2.5 million to $35 million. Many mid-market contractors who previously triggered Cost Accounting Standards coverage will now be fully exempt on most work.
• Full CAS threshold: Increased from $50 million to $100 million. Fewer business units will need Disclosure Statements. More firms stay under modified CAS or drop out of CAS entirely.

In practical terms: if your annual defense revenue is under $35 million, you probably just got freed from one of the most burdensome compliance frameworks in government contracting. That's real money saved on accounting overhead, and it means you can compete on more contracts without restructuring your back office.

Non-Traditional Contractors Get a Fast Lane

The NDAA creates explicit carve-outs for non-traditional defense contractors (NDCs) -- companies that haven't historically done DoD work but have relevant commercial capabilities. NDCs are now exempt from:

• FAR Part 31 cost principles
• Truthful Cost or Pricing Data requirements
• DFARS business system and cost or pricing rules

This means NDCs can propose using commercial pricing, market-based rates, or catalog pricing without restructuring their accounting practices to match government standards. If you're a tech company or cybersecurity firm that's been hesitant to enter the defense market because of the compliance maze, that barrier just dropped significantly.

Past Performance Rules Are Expanding

One of the biggest obstacles for small contractors breaking into defense has always been the past performance catch-22: you can't win work without past performance, and you can't get past performance without winning work.

Section 824 of the NDAA takes a direct swing at this. It directs the Secretary of Defense to issue guidance on:

• Accepting commercial and non-government projects as relevant past performance
• Methods for validating non-governmental past performance references
• Using alternative evaluation approaches -- like technology demonstrations and testing -- for requirements that don't have much precedent

The same section also requires the Defense Acquisition Regulations Council to identify and remove procurement policies that create barriers to small business participation. The Secretary then has two years to implement those changes.

This isn't a vague aspiration. It's a statutory mandate with a timeline. If you've been shut out of opportunities because your past performance was all commercial, that door is opening.

Where the Money Is Going

The overall spending trend is clear: defense budgets will continue growing through the end of the decade. Geopolitical risk, rearmament priorities, and bipartisan support for military modernization are driving sustained investment. Here's where the FY2026 dollars are concentrated:

Cybersecurity and IT modernization. Expanded federal efforts to harden cyber defenses and unify cybersecurity standards across the defense industrial base. CMMC enforcement begins in November. Contractors providing cybersecurity services, managed security, and compliance consulting are positioned well.

Autonomous systems and AI. Significant increases in funding for unmanned vehicles, robotics, counter-UAS tools, and AI-enabled threat detection. Roughly $850 million is earmarked for contractor support in advanced data analysis alone. Small firms with AI/ML capabilities or data engineering expertise should be tracking these opportunities.

Microelectronics. R&D growth for secure, next-generation chips needed for advanced sensors, embedded systems, and AI computing. The CHIPS Act is a separate funding stream, but the NDAA reinforces the defense angle.

Missile defense and hypersonics. The Golden Dome for America (GD4A) program represents a multi-year, multi-billion-dollar investment in next-generation missile defense. Prime contractors will need extensive subcontractor support across manufacturing, integration, and testing.

Space systems. Continued funding expansion for Space Force capabilities, satellite infrastructure, and space domain awareness. Forbes estimates the combined Air Force and Space Force implications alone could push toward $1.5 trillion in total defense spending when you account for all related programs.

Best Value Over Lowest Cost

Section 1801 redefines "best value" as "the optimal combination of cost, quality, technical capability or solution quality, and delivery schedule." That's a shift from the lowest-price-technically-acceptable (LPTA) approach that has dominated many procurements.

For small contractors, this matters. LPTA evaluations favor large incumbents who can absorb thin margins. Best-value evaluations create room for smaller firms to win on technical merit, innovation, and speed -- areas where lean companies often have an edge over large bureaucratic primes.

The NDAA also requires DoD purchases under GSA's Multiple Award Schedule to be based on best value rather than lowest overall cost. This change applies only to defense acquisitions, not civilian agencies, but it signals where procurement philosophy is heading.

Project Spectrum: Free Cybersecurity Resources for Small Contractors

Section 1807 establishes Project Spectrum, an online DoD program that provides small and medium defense contractors with digital resources, training, and services for cybersecurity compliance. If you're a small contractor working toward CMMC readiness, this is a free government resource designed specifically for you.

The program is intended to increase awareness of cybersecurity requirements and make compliance more accessible. It won't replace a gap assessment or do the remediation work for you, but it's a starting point -- and it signals that DoD recognizes the compliance burden on small businesses and is investing in support.

A Warning on Frivolous Protests

One provision worth noting: Section 875 creates financial penalties for incumbent contractors who file frivolous bid protests at the GAO to delay contract transitions. If a protest is dismissed for lacking any reasonable legal or factual basis, the incumbent forfeits up to 5% of the total contract value.

This is good news for challengers. Incumbent companies have long used protest filings as a delay tactic -- triggering an automatic stay on the protested contract, which often results in bridge contracts or extensions that keep the incumbent working. The new penalty creates actual financial risk for that strategy.

What Small Contractors Should Do Now

The FY2026 NDAA is a tailwind for small defense contractors. But tailwinds only matter if your sails are up. Here's how to take advantage:

1. Reassess your CAS and cost accounting posture. If the threshold increases exempt you from CAS or certified cost data requirements, talk to your accountant. You may be able to simplify your accounting structure and reduce overhead costs, making you more competitive on price.

2. Update your capabilities narrative. With commercial past performance now becoming acceptable, make sure your SAM.gov profile and capability statements highlight relevant commercial work -- not just prior government contracts.

3. Track the spending priorities. Cybersecurity, AI, autonomous systems, microelectronics, and missile defense are where the growth is. If your NAICS codes overlap with these areas, the volume of relevant solicitations is going to increase throughout 2026.

4. Get your CMMC house in order. The NDAA reinforces cybersecurity requirements across the defense industrial base. Phase 2 enforcement starts November 10, 2026. If you handle CUI, you need a plan.

5. Watch for the regulatory changes. Many NDAA provisions require follow-on rulemaking within 180 days to two years. The actual implementation details -- how past performance will be evaluated, how barrier-removal recommendations will be implemented -- will come through DFARS updates and DoD guidance. Stay current.
