- Lockheed Martin is America’s largest defense contractor, and it received $61.4 billion in Department of Defense contracts in 2023.
- RTX Corporation (formerly Raytheon Technologies) ranks in second, with $24.1 billion in awarded contracts that year.
- Following closely behind is General Dynamics, which operates four main business segments: aerospace, marine systems, combat systems, and technologies.
In 2023, the Department of Defense budget totaled $609.2 billion, equal to $1,819 for every U.S. resident.
Following a wave of consolidation in the past few decades, a handful of defense contractors dominate the industry. At the same time, many of these firms provide a diversified range of capabilities—from munitions and nuclear submarines to services that manage IT infrastructure.

Following next in line is RTX, formerly Raytheon Technologies, at $24.1 billion in contracts. As the world’s most valuable defense company, RTX is worth $183 billion, driven by its broad range of missile systems, commercial aviation, and advanced technologies.
Ranking in third is Virginia-based General Dynamics, which typically generates the most revenue from its IT systems and marine divisions.
Overall, the number of prime contractors for the Department of Defense has declined from 51 in the 1990s to just five today. These legacy firms include Lockheed Martin, RTX Corporation, General Dynamics, Boeing, and Northrop Grumman.
