What Companies Have U.S. Military Contracts? Top 25 Defense Contractors Ranked (2026)
The definitive ranked list of companies holding U.S. military contracts in 2026, with dollar values, what they build, and how small businesses compete for DOD work.
The Short Answer
Thousands of companies hold U.S. military contracts, ranging from trillion-dollar primes like Lockheed Martin to one-person machine shops. In FY2025, the Department of Defense obligated approximately $460 billion in contract spending across more than 100,000 vendors. However, the top 25 contractors account for roughly 55% of all DOD contract dollars. Below is the complete ranked breakdown.

Breakdown by Military Branch
DOD spending is not evenly distributed. Each branch has distinct procurement patterns and preferred vendors.
Army (~$140B in contracts)
Navy/Marine Corps (~$155B in contracts)
Air Force (~$120B in contracts)
Space Force (~$30B in contracts)
Defense Agencies (DARPA, DISA, MDA, DLA — ~$65B)
How Small Businesses Win DOD Contracts
The DOD has a statutory small business contracting goal of 23% of prime contract dollars and consistently reports achieving it. In practice, that translates to over $100 billion annually flowing to small businesses.
Key Entry Points
Subcontracting With Primes
For contracts above $750,000, large primes must submit subcontracting plans with small business targets. This creates a massive sub-tier market.
| Prime | Reported Small Biz Sub % | How to Find Opportunities |
|---|---|---|
| Lockheed Martin | ~33% of subs | supplierconnection.lockheedmartin.com |
| RTX | ~35% of subs | rtx.com/suppliers |
| Boeing | ~30% of subs | boeing.com/company/doing-business-with-boeing |
| Northrop Grumman | ~32% of subs | northropgrumman.com/suppliers |
| General Dynamics | ~28% of subs | gd.com/suppliers |
You can also use the DOD Subcontracting Directory at dodsubcontracting.com to identify subcontracting contacts at every large prime.
Tracking Military Contracts in Real Time
Public data on DOD contracts is available through FPDS and USASpending.gov, but both are difficult to search at scale. Fed-Spend aggregates these sources and adds recompete tracking, so you can monitor when major DOD vehicles are expiring, which incumbents hold them, and when replacement solicitations are likely.

FAQ
What company has the most military contracts?
Lockheed Martin holds the most U.S. military contracts by dollar value, with approximately $75 billion in annual DOD obligations. They are the sole manufacturer of the F-35 Joint Strike Fighter, the DOD's largest acquisition program, and hold major contracts across missiles, space systems, rotary-wing aircraft, and C4ISR. The next largest is RTX (Raytheon) at roughly $38 billion.
Can small businesses get military contracts?
Yes. The DOD awards over $100 billion annually to small businesses through prime contracts, subcontracts, and SBIR/STTR programs. Set-aside programs (8(a), SDVOSB, HUBZone, WOSB) reduce competition, and sole-source thresholds allow agencies to award up to $4.5 million to 8(a) firms without competition. The biggest opportunity for small businesses is often subcontracting with the top 25 primes, who must meet small business subcontracting plan requirements.
How do I find out who has a specific military contract?
Search FPDS.gov or USASpending.gov using the contract number, agency, or keywords. Fed-Spend provides a faster search experience with incumbent tracking and recompete alerts. You can also check SAM.gov for active solicitations and awards, or search the DOD contract announcements published daily at defense.gov/News/Contracts.
