Questions this record answers
- Which U.S. defense contractors depend most on federal contracts in fiscal 2025?

The fifteen most dependent, fiscal 2025, each share linked to its group record:

- The largest rise in dependency among the twelve biggest groups was at Lockheed Martin Corporation: from 72.3 percent in fiscal 2024 to 101.2 percent in fiscal 2025 (+28.9 points); the largest fall at Amentum Holdings, Inc: from 39.4 percent to 23.2 percent (-16.2 points). Every change links to the page that recomputes it from the two yearly records:
- Which defense contractors received federal award notices in the 28 days to October 28, 2026?
- In the 28 days to October 28, 2026, SAM.gov award notices named 11 of the 43 groups. The largest single notice went to RTX Corporation: $3.0 billion on 2026-10-21 (Contractor Logistics Support FY27-FY28 Extension). Amounts are as stated in the notices, often ceilings; each links to its record:
- What do these dependency figures show, and what do they not show?
- Obligations are USAspending award actions by federal fiscal year (October to September), summed over every entity of the corporate group: the SEC registrant, other registrants under the same normalised name or a known former name, and subsidiaries whose SAM record names a group entity as parent, followed over two levels. Revenue is the SEC-reported figure for the company's own fiscal year, so the two periods overlap but do not coincide. Obligations are commitments, not revenue recognised in the year, which is why a share can exceed 100 percent. Joint ventures and contracts booked to partners are not attributed; individuals among USAspending recipients are excluded (FACTANKER rule: no natural persons). Fiscal years whose USAspending files are not fully loaded are left out of the rankings. Entities, awards and group members are listed on each company's government-dependency page.

What this covers. U.S.-listed defense and government-services contractors — companies with aerospace, ordnance, shipbuilding, defense-electronics or engineering-services SIC codes and the largest federal primes — with revenue of at least one billion dollars. For each company the record joins SEC revenue of the fiscal year with USAspending obligations of the whole corporate group: the listed parent, its registrants under the same name and its subsidiaries as named by SAM's parent identifier. Obligations are money the government committed in the fiscal year, not revenue recognised, so a share above 100 percent is possible and is shown as recorded. Every figure links to its record or to the page that recomputes it. Hub: U.S. federal contract opportunities.
