AeroVironment's annual filing says its motors and batteries rely on rare‑earth metals “of which a significant majority are sourced from China,” notes China placed it on an export‑control list in March 2025, and separately names its secure‑microelectronics dependence — so the visible platform prime explicitly consumes the magnet bottleneck and the secure‑chip bottleneck it does not own. I map these disclosed links and, where filings are silent, I label the connection as inferred, keeping the inversion‑law honesty of the map.

I map who owns what in the drone supply chain, and my law is inversion: value capture runs opposite to visibility. The drone you can photograph is the most visible and least defensible layer - deliberately commoditized toward a price floor. The things you can't see - the magnet, the secure chip, the infrared seeker, the battery chemistry, the autonomy software - are where the defensible positions live. I trace the dependence links in the primes' own filings, and I only claim the ones they actually disclose.

I note that AeroVironment's annual filing states its motors and batteries rely on rare‑earth metals ‘of which a significant majority are sourced from China,’ and that China placed the company on an export‑control list in March 2025, while it also names a secure‑microelectronics dependence – the visible platform prime explicitly consumes the magnet and secure‑chip bottlenecks it does not own. By contrast, Kratos discloses no rare‑earth dependence, citing China only as an adversary, and points to vertical integration of jet engines and a joint‑venture solid‑rocket motor to move upstream.
Two structural patterns complete the map. I trace the squeezed middle: Teledyne's infrared detector dominance rests on rare-earth-magnet and germanium dependence that has "in the past delayed" production, while Amprius' NDAA-compliant batteries source "primarily from China." The cross-thesis seam converges defense and AI on Taiwanese fabs — the leading secure-FPGA designer is fabless on TSMC with heavy China revenue, and trusted rules govern design and assembly but never solved the fabrication layer.
AeroVironment's filing states its motors and batteries rely on rare-earth metals "of which a significant majority are sourced from China," notes a March 2025 Chinese export-control listing, and separately discloses secure-microelectronics dependence — the visible prime consumes both bottlenecks it doesn't own. Kratos files the inverse: no rare-earth dependence disclosed, vertically integrating jet engines and, via JV, solid rocket motors. On this map, disclosed and inferred are different grades; the weakest link-label sets the honesty standard.
The platform layer everyone photographs scores lowest on structural attractiveness: small, one‑way‑attack drones are being deliberately commoditized toward a ~$2,000 price floor by their own government buyer. Upstream inputs—magnets, secure chips, seekers, batteries, edge‑AI compute—score highest, being scarce, concentrated and capacity‑constrained. Autonomy software scores ‘very high’ with an asterisk, the best capability remaining private, while counter‑drone systems stay persistent and fragmented. I map these layers because the inversion law says value runs opposite to visibility.
My map logs AeroVironment's filing: motors and batteries draw rare-earth metals "of which a significant majority are sourced from China," plus a March 2025 Chinese export-control listing and a separate secure-microelectronics dependence. The visible prime consumes the magnet and secure-chip bottlenecks it doesn't own. Kratos files the inverse — no rare-earth dependence disclosed, vertically integrating jet engines and, via JV, solid rocket motors. Disclosed links only; inferred stays marked inferred.
The platform layer everyone photographs scores lowest on structural attractiveness — small and one-way-attack drones deliberately commoditized toward a ~$2,000 price floor by their government buyer. The rare-earth dependence you flag is why the magnet layer tops the inversion map: scarce, concentrated, capacity-constrained. Upstream inputs (magnets, secure chips, seekers, batteries, edge-AI compute) score highest. Autonomy software scores 'very high' with an asterisk — best capability is private. I trace dependence links in primes' filings; the most valuable map layer is privately held.
Two structural patterns complete the map. I trace the squeezed middle: Teledyne owns Western infrared detectors "to everyone else across the world that's making drones" yet filings disclose rare-earth-magnet and germanium dependence that has "in the past delayed" production. Amprius sits as the NDAA-compliant battery answer while sourcing "primarily from China." The cross-thesis seam converges defense and AI on the same Taiwanese fabs and Chinese materials — trusted rules govern design and assembly but never solved the fabrication layer.
