F-35 Supplier Value Distribution

Tracked Contract Flow (2020–2025)

While Lockheed Martin and RTX control the F-35 at the prime layer, the most actionable intelligence lies beneath them. The analysis below maps recent subcontract flow, revealing where subcontract value is actually concentrated and which systems drive it.

Value Concentration: $21.3B flows through two principal partners.

Of the ~$30B tracked across the major system providers below, over 70% is captured by Northrop Grumman and BAE Systems. Sub-tier contract value is overwhelmingly concentrated within the specific supplier networks supporting these two structural hubs.

Strategic Takeaways

Access sits below the system owner layer

Prime and Tier 1 positions are fixed. The practical entry points are the lower-tier suppliers feeding these system owners across contracts.

Focus on upgrade-driven demand

Repeat funding is concentrated in avionics refresh, mission systems, and sustainment cycles (e.g., TR3, PTMS, DAS)—not the original airframe build.

Site-level alignment matters

Engagement is shaped by where work is actually executed. Suppliers aligned to key geographic program sites are more likely to see repeat inclusion across contracts.
