Mk-0 campaign · Phase SIM-1 active
Before Pyrois touches a runway, it flies in code. Our Mk-0 campaign runs the real autopilot through autonomous missions in high-fidelity simulation — every flight logged, every lesson kept.
Inside the Mk-0 programThe Aethon method
Mk-0 flies the same ArduPilot code that will fly the real aircraft — through waypoint autonomy, endurance profiles, and multi-vehicle coordination. Hardware gets built when the data says so, not before.
See the flight test phasesFlight systems
Long-endurance airframes for persistent sensing and low-cost attritable mass — designed for performance, manufacturability, and domestic production from day one.
Applied research
Focused programs in propulsion, materials, and autonomy. We publish what we can, fly what we prove, and build what the data supports.
Long-endurance ISR platform
Persistent surveillance for contested airspace. Now flying autonomous missions in simulation under the Mk-0 campaign.
Mk-0 · In simulationAttritable swarm airframe
A low-cost, expendable airframe designed for coordinated flight. Multi-vehicle simulation is phase three of the Mk-0 campaign.
Concept phaseNothing here survives on slideware.
The hardest problems in flight are solved where engineering and research meet. Every claim on this site is backed by a logged flight — simulated today, physical next.
The Mk-0 campaign is logged publicly, phase by phase, on our updates page.
