7 Defense Contract Categories About to Explode: Where the $1 Trillion Military Buildup Is Going and How to Get In

$1.05 Trillion. That Is Not a Typo.

The United States will spend $1.05 trillion on defense in fiscal year 2026 - a 17% increase over last year. That figure includes $893 billion from normal appropriations and $152.3 billion in reconciliation funds that the Pentagon is obligating in full this fiscal year.

To put this in perspective: the entire GDP of Saudi Arabia is $1.06 trillion. The U.S. defense budget now matches the economic output of a G20 nation.

This is not spread evenly. Specific contract categories are absorbing outsized shares of the increase. If you are a federal contractor - or want to become one - knowing exactly where these dollars are flowing is the difference between watching from the sideline and winning work.

Here are the 7 categories, the specific programs driving them, the NAICS codes that matter, and exactly how small businesses can get in.

1. Drones and Counter-Drone Systems

The Money: $20+ Billion

This is the fastest-moving contract category in the Department of War right now.

Anduril Industries - $20 Billion (Awarded March 14, 2026)

The U.S. Army awarded Anduril a 10-year enterprise contract worth up to $20 billion to consolidate AI battlefield technologies through their Lattice platform. This single award unifies over 120 separate previous procurement actions into one framework. The contract runs through March 2036 with a five-year base and five-year option.

Drone Dominance Initiative - $150 Million (Phase 1)

The Pentagon is ordering 30,000 one-way attack drones at $5,000 per unit through the "Drone Dominance" program. Twenty-five drone companies competed in the "Gauntlet" at Fort Benning. The goal: equip every Army squad with attack drones by end of FY2026. Phase 2 testing begins August 2026 with enhanced counter-UAS environments. The Pentagon wants to drive the per-unit cost to $2,000.

Combat Deployment: LUCAS Drone

The Low-Cost Uncrewed Combat Attack System - built by Arizona-based SpektreWorks - saw its first combat deployment in Iran on March 3, 2026. At $35,000 per unit, it replaces missions previously requiring $20-40 million MQ-9 Reapers. Just eight months from Pentagon unveiling to combat deployment.

NAICS Codes to Watch

Small Business Angle

The Drone Dominance program was specifically designed to pull in non-traditional defense companies. If you manufacture components (motors, cameras, GPS modules, batteries, composite airframes), the primes need subcontractors. Anduril's $20B contract will cascade through hundreds of subcontracting opportunities - search for their name on Fed-Spend and track upcoming subcontracting plans.

What to Search on Fed-Spend

Search for "UAS," "counter-UAS," "unmanned aerial," "drone," "Anduril," and "autonomous" filtered by DOD. Set alerts for NAICS 336411 and 334511 with set-aside filters.

2. Munitions and Ammunition Production

The Money: $25+ Billion

The reconciliation bill alone dedicates approximately $25 billion to munitions procurement and supply chain expansion. This is the largest single-year munitions investment since World War II.

Key Programs:

Industrial Base Expansion:

Parsons Corporation received a $100 million task order to design and build a new rocket motor manufacturing facility in Perry, Florida. Construction timeline: two years. This is one of dozens of munitions facility expansions underway.

NAICS Codes to Watch

Small Business Angle

The Pentagon cannot expand munitions production through the existing prime base alone. They need new suppliers for everything from propellant chemicals (small business set-asides through Naval Surface Warfare Center) to precision machining, quality control, packaging, and logistics. The $1 billion+ allocated through the APFIT (Accelerate the Procurement and Fielding of Innovative Technologies) program has awarded average grants of $30 million per project to small businesses - with a record single award of $49.7 million.

What to Search on Fed-Spend

Search for "ammunition," "munitions," "ordnance," "propellant," "rocket motor," and "bomb body" filtered by Army and Navy. Watch for set-asides under NAICS 332993 and 332994.

3. Shipbuilding and Naval Systems

The Money: $15+ Billion

Naval procurement received massive funding increases in both regular appropriations and reconciliation.

Key Programs:

NAICS Codes to Watch

Small Business Angle

Shipbuilding supply chains run deep. The $226 million in maintenance contracts alone was split across 14 separate shipyards in Virginia, California, Wisconsin, and other states. Machine shops, welding operations, electrical contractors, and marine engineering firms all play a role. The Columbia-class industrial base investment ($1.4 billion) specifically targets supplier development.

What to Search on Fed-Spend

Search for "shipbuilding," "naval vessel," "submarine," "destroyer," "shipyard," "marine," and "hull" filtered by Navy. NAICS 336611 and 336612 are the primary codes.

4. Nuclear Modernization

The Money: $17+ Billion

The U.S. is modernizing all three legs of the nuclear triad simultaneously for the first time since the 1980s. This is a multi-decade commitment with contracts that will run into the 2030s and beyond.

Key Programs:

NAICS Codes to Watch

Small Business Angle

The B-21 supply chain alone spans hundreds of subcontractors across 40+ states. Sentinel ICBM is earlier in its lifecycle - the supply chain is still forming. Companies that win positions now will hold them for decades. Look for small business set-asides in facility construction, environmental remediation, and specialized manufacturing.

What to Search on Fed-Spend

Search for "B-21," "Sentinel," "nuclear," "ICBM," "strategic deterrent," "SLCM," and "triad." Filter by Air Force and Navy. Track Northrop Grumman subcontracting plans for the B-21.

5. Cyber and Space Warfare

The Money: $5+ Billion and Growing Fast

This is the category with the most asymmetric opportunity for small businesses. Cyber and space contracts skew heavily toward software, which has lower barriers to entry than hardware manufacturing.

Key Programs:

NAICS Codes to Watch

Small Business Angle

This is the best category for small and non-traditional defense companies. AFWERX and SBIR (Small Business Innovation Research) contracts provide funding pathways specifically designed for startups and small firms. CMMC (Cybersecurity Maturity Model Certification) compliance is required but achievable. Many cyber contracts are 8(a) and small business set-asides.

What to Search on Fed-Spend

Search for "cyber," "space," "satellite," "electronic warfare," "SBIR," and "AFWERX" filtered by Space Force and Air Force. Set-aside filter for 8(a) and small business under NAICS 541512.

6. AI and Autonomous Systems

The Money: $10+ Billion Across Programs

AI is no longer a research category - it is a procurement category. The Anduril $20B contract alone signals that DoD views AI as an enterprise capability, not a science experiment.

Key Programs:

NAICS Codes to Watch

Small Business Angle

DARPA's Commercial Solutions Opening is designed for companies that have never worked with the Pentagon. The APFIT program has awarded over $1 billion to small and non-traditional defense firms in FY2026 alone. If you build AI/ML software, the pathway exists. Start with SBIR Phase I ($150K-250K contracts) to establish your past performance record.

What to Search on Fed-Spend

Search for "artificial intelligence," "machine learning," "autonomous," "Lattice," "DARPA," and "AI" filtered by all DoD agencies. Watch for SBIR and STTR solicitations.

7. Defense Industrial Base Infrastructure

The Money: $5+ Billion in Direct Investment

The Pentagon learned from the Ukraine conflict that surge production capacity matters more than peacetime efficiency. Now they are investing directly in the industrial base itself.

Key Programs:

NAICS Codes to Watch

Small Business Angle

This is where construction, engineering, and facility services companies enter the defense ecosystem. Building and maintaining defense facilities requires the same trades as commercial construction - but with security clearances and CMMC compliance. Many of these contracts are set aside for small businesses, particularly in the 8(a) and HUBZone programs.

What to Search on Fed-Spend

Search for "industrial base," "ammunition plant," "GOCO," "facility construction," "DPA," and "production capacity" filtered by Army and DoD. NAICS 236210 is the primary construction code.

The Timeline: What Is Happening When

Right Now (March 2026)

Next 90 Days (Q3 FY2026: April-June 2026)

6-12 Months Out (Q4 FY2026 - Q1 FY2027)

How to Get In: The 5-Step Action Plan

Step 1: Get Your NAICS Codes Right

Cross-reference the NAICS codes listed above with your capabilities. Register them in SAM.gov. Many contractors lose set-aside eligibility by choosing the wrong codes - 34% of small businesses that lost set-aside status did so due to NAICS misclassification.

Step 2: Achieve CMMC Compliance

Every defense contract now requires some level of Cybersecurity Maturity Model Certification. Level 1 (self-assessment) is achievable for most companies. Start the process now - it takes 3-6 months.

Step 3: Set Up Real-Time Alerts

These contracts move fast. The LUCAS drone went from unveiling to combat deployment in eight months. You cannot check SAM.gov once a week and expect to catch these opportunities. Set up automated alerts on Fed-Spend for the NAICS codes and keywords in your category.

Step 4: Target Subcontracting First

If you have never won a federal prime contract, start as a subcontractor to the primes. Anduril, Northrop Grumman, Raytheon, Lockheed Martin, and General Dynamics are all required to subcontract a percentage to small businesses. Track their subcontracting plans through the SubNet system.

Step 5: Build Past Performance

Your first contract establishes your CPARs (Contractor Performance Assessment Report) record. Every subsequent bid is easier. Use Fed-Spend's search to find opportunities in your NAICS code where the incumbent has weak CPARs ratings - that is where disruption happens.

The Bottom Line

$1.05 trillion is flowing through the defense industrial base. The seven categories above are absorbing the largest increases: drones, munitions, ships, nuclear modernization, cyber/space, AI, and infrastructure.

The firms that win this work are the ones that know exactly where the money is going, have their NAICS codes and compliance in order, and are tracking opportunities in real time - not reading about them in trade publications after the response deadline has passed.

The money is moving. The contracts are being posted. The only question is whether you can see them.
