Persistent observation.
Modular response.
A long-endurance recon platform, a family of mission modules, and a propulsion line built to be printed in-region. Developed by Dragon Works.
A modular aerospace platform.
Observation decoupled from action.
The unit of work is a closed loop: sense → decide → effect → re-task. The aircraft is sized for persistence. Action is delegated to a module sized for the task.
Drawings are the contract.
The most valuable aircraft is the one that remains.
71SR is a long-endurance recon platform. High aspect-ratio wing, blended centre body, composite construction. Sized for persistence, not speed.
Recon platform.
High aspect-ratio wing. Blended centre body. The wing dominates the airframe; the fuselage is sized to carry a payload bay and a module.
Performance figures are not published at this revision.
Concept sheets.
Working artwork from the platform definition phase. Indicative, not final.
A family, not a vehicle.
One common payload interface. Mission modules are interchanged in the field. Toothless is one option.
Resilient comms mesh and BLOS relay.
EO/IR and SAR survey payloads.
Passive RF survey and emitter mapping.
Compact autonomous interceptor module.
Mission modules.
3D printed.
No magnets.
Developed with our motor division, MotorDope. An additive-manufactured induction motor designed to be built where it is needed, inspected at every layer, and repaired in the field.
- — no rare-earth magnets
- — printed in-region
- — inspectable at every layer
- — field repairable
Additive induction motor.
Squirrel-cage rotor. Printed stator. No permanent magnets and no rare-earth dependency. The motor is co-developed with MotorDope, our motor division.
Additive manufacturing is chosen for supply-chain reasons before it is chosen for geometry. The motor is meant to be printed where it is needed.

Engineering notes.
Selected. Expanded entries reflect what is safe to publish at this revision.
note-033 · manufacturing · build-to-print
Drawings are the contract. Anything that cannot be drawn, toleranced and inspected does not ship. The intent is to keep the engineering organisation, the shop floor and the field on the same revision of the same document — and to make revision discipline cheaper than rework.
note-021 · mission · loiter and recovery envelope
The on-station band is sized so that re-tasking latency is bounded by sensor cadence. Recovery is bracketed by handoff to a stationary asset.
note-029 · spectrum · superiority as a defensive posture
Spectrum control is treated as an extension of the shield. Counter-electronics authority is held in reserve.
