Air, sea, and ground autonomy has moved from research-lab project to procurement line item. Every active US ground commander now plans operations around drones. Below: the six layers of the autonomous-systems supply chain, with the US-listed public companies operating in each.
Airframes at the apex. Sensors at the foundation. The full unmanned-systems supply chain, US-listed only.
The pure-play unmanned aerial vehicle makers. Small drones, loitering munitions, ISR platforms, and launch vehicles for satellite payloads. Higher growth, higher variance, the names defense primes acquire when the procurement winds turn.
The five tier-one defense contractors with unmanned programs across every domain: MQ-9 Reaper, RQ-180, X-47B, Switchblade, NGAD wingmen. Slower revenue growth, but the contracts that move the budget needle.
Detection, tracking, and defeat systems against hostile drones. Counter-drone spending has expanded since 2022, and bases, ships, and convoys increasingly treat it as critical infrastructure.
Surface and underwater unmanned vehicles. Replenishment ships that drive themselves, mine-countermeasure drones, and the autonomy-capable shipbuilders fielding them at the Navy’s pace.
The decision layer running on top of the hardware. Embedded operating systems, computer-vision pipelines, mission-planning AI, and the data platforms ingesting every sensor feed back to command.
Electro-optical, infrared, SAR, and signals-intelligence payloads. The cameras, radars, and antennae bolted to unmanned platforms. Lower-profile names, but they ship across many programs.
Constituent lists are reviewed quarterly against revenue mix, segment disclosures, awarded contract activity, and Congressional appropriation language. Quotes are sourced from licensed market data; the Veridion Score is computed from six published factors. Inclusion is not a recommendation.
