The Largest Aerospace & Defense Companies by Federal Revenue (2026 Rankings)
Ranked by actual FY2026 federal contract obligations, not press releases: Lockheed Martin leads aerospace manufacturing at $26.8B, Boeing follows at $17.4B, RTX at $7.7B. The full ranking of who is winning the $72.9B federal aerospace market, from live USASpending data.
How this ranking is different
Most "largest aerospace companies" lists rank total corporate revenue - commercial airliners, engines for private jets, foreign sales. This one ranks something more specific and more verifiable: actual U.S. federal contract obligations in aerospace manufacturing (NAICS 3364) for FY2026 to date, pulled live from USASpending.gov on July 20, 2026 and aggregated across each company's subsidiaries.
The market: $72.9 billion obligated between October 1, 2025 and July 19, 2026 - tracking about 4% below the $75.9B pace of the same period last fiscal year.

Five things the ranking tells you
1. This is a duopoly with a supporting cast. Lockheed and Boeing together hold 60.5% of federal aerospace manufacturing dollars. Add RTX and Northrop and the top four families control 78%. The remaining ~$16B is split across hundreds of manufacturers.
2. Lockheed's lead is structural. $26.8B in nine and a half months is the F-35 program plus missiles (JASSM, PrecisionFires), rotary (Sikorsky), and space. No single recompete threatens it; the position is a portfolio.
3. Boeing's federal aerospace business is bigger than its headlines. Between KC-46, F-15EX, MQ-25, T-7A, and space launch, Boeing pulled $17.4B despite years of fixed-price development losses - and its expiring-contract profile shows the recompete exposure that comes with it.
4. The buyer is effectively one customer. DoD accounts for $70.3B - 96% of all federal aerospace manufacturing obligations. NASA adds $1.8B, DHS $0.4B. If you sell into this market, you sell to the Pentagon's program offices, full stop.
5. The disruption story is real but small - for now. AeroVironment ($460M) cracked the top 15 on drone systems, Kratos and Anduril keep winning autonomy awards, and the sub-$100M tier is full of first-time space and UAS manufacturers. The insurgents are growing fast from a small base while the incumbents defend nine-figure programs.
What this means if you are not on the list
The $72.9B headline market is closed to new entrants at the prime level - but three layers underneath it are not:
Methodology
Obligations are federal prime contract obligations coded to NAICS 3364 (Aerospace Product and Parts Manufacturing), October 1, 2025 through July 19, 2026, from USASpending.gov. Subsidiaries are merged into corporate families (Sikorsky into Lockheed; Bell into Textron; Pratt & Whitney and Raytheon into RTX; Gulfstream into General Dynamics). Companies whose federal work is mostly coded to services or electronics NAICS (much of L3Harris, BAE, General Dynamics) will rank lower here than on total-defense-revenue lists - see our top 25 defense contractors by total federal revenue for that view.
