About Government Contractors

The federal government spends over $700 billion annually on contracts, making it the largest buyer of goods and services in the world. The top government contractors range from defense giants building aircraft carriers and fighter jets to technology firms modernizing agency IT systems to healthcare companies managing benefits for millions.

Understanding which companies dominate federal contracting is essential for businesses looking to enter the market as subcontractors, teaming partners, or competitors. Each contractor has distinct agency relationships, security clearances, and past performance that define their competitive position in the federal marketplace.
