What contractors work with DoD?

The Department of Defense buys from thousands of vendors every year, but the largest share of dollars goes to a small set of prime contractors: Lockheed Martin, Boeing, RTX (formerly Raytheon), General Dynamics, Northrop Grumman, BAE Systems, L3Harris, and Huntington Ingalls.

Below the primes, the DoD also obligates significant dollars to mid-tier services firms and an enormous long tail of small businesses, many through set-aside programs. The breakdown below shows who is moving the most today and which categories of work are most active.
