Three Standard Kit Sizes

Standard.
Large.
Heavy.

All kits manufactured at L4 from asteroid carbon. All ship dry — no hydrogen. The graphene photovoltaic envelope cracks onboard water into hydrogen in 27–81 minutes from solar power alone. No gas handling. No compressed gas transport risk. Water in. Hydrogen out. Dirigible up. No ground contact required at any point.

LEO Deployment — No Ground Contact

Kit released from Pro-Pel vehicle in LEO. CNT frame deploys in vacuum. Envelope seals. DRAD-1 manages de-orbit burn. As the kit descends through 25–20 km the PV layer activates and electrolysis begins. Hydrogen fills the envelope on descent. Buoyancy arrests the kit at operational altitude. Self-braking entry — no heat shield required. Props deploy. Station acquired. Operational in 2–4 hours from release. No aircraft. No ground crew. No infrastructure of any kind.

Propulsion Architecture

Solar Power.
Water Feedstock.
Infinite Endurance.

The graphene PV envelope generates 2.4–5.4 MW from solar flux at 18–20 km altitude — 30% higher than at sea level. All propulsion, electrolysis, DRAD-1, and payload systems run from this power indefinitely. The only consumable is water — freely available everywhere on Earth and resupplied by passing water delivery ships.

☀️
Graphene PV Envelope
The envelope IS the power plant. Integrated photovoltaic graphene layers. 2.4–5.4 MW at 18–20 km. Powers everything. No separate solar panels. No batteries required for daytime operations. The structure that provides lift also provides power.
💧
Solar Water Electrolysis
PV power cracks onboard water into hydrogen for lift and thruster propellant. 27 minutes to fill a 20m envelope from empty at full PV power. Ships dry — no compressed gas transport. Water tank resupplied by passing water delivery ships.
🌀
Featherable Retractable Props
CNT composite propeller pods. Featherable — blade pitch adjusts from full thrust to zero drag. Retractable — fold flush with envelope for ascent, transit, and stealth. 4–6 pods at equatorial positions. Electric motors from PV power. Zero fuel consumption.
💨
H₂ Cold Gas Thrusters
Fine attitude control. The lifting gas IS the thruster propellant. 8–12 nozzles around equator. Bleeds from envelope hydrogen supply. Replenished by onboard electrolysis. Rapid attitude correction with no separate propellant required.
Electrothermal Thrusters
PV-heated hydrogen exhaust. Higher specific impulse than cold gas. Used for deliberate zone-to-zone repositioning. Not continuous — for occasional redeployment to a new target. 4 units. DRAD-1 manages all repositioning manoeuvres.
⚖️
DRAD-1 Buoyancy Management
Four variables managed simultaneously: electrolysis rate, hydrogen vent rate, water ballast level, propeller pitch. Day/night temperature compensation automatic. Altitude precision: ±50m. DRAD-1 operates indefinitely without ground operator.
Lifting Harness

Two Dirigibles.
Four Dirigibles.
Any Altitude.

CNT spreader frame connects multiple dirigibles as a single coordinated unit. Master DRAD-1 manages all dirigibles simultaneously. At 3 km altitude the lift numbers are dramatically higher than at stratospheric altitude — the same kit becomes a serious heavy lift platform.

2-DIRIGIBLE · 18 KM ALTITUDE
543 kg
CNT SPREADER BAR · 25M SPAN · 35 KG HARNESS
Two 20m envelopes separated by spreader bar. Central load beam rated 6,000 kg. Master DRAD-1 coordinates both as single unit. 8 propeller pods total. Stratospheric monitoring and ARP payloads.
4-DIRIGIBLE · 18 KM ALTITUDE
1,086 kg
CNT SPREADER FRAME · 25M × 25M · 70 KG HARNESS
Square array with diagonal bracing. Load beam rated 12,000 kg. Master DRAD-1 + 3 slave nodes. 16 propeller pods total. Heavy stratospheric payloads — mirror arrays, large sensor suites.
2-DIRIGIBLE · 3 KM ALTITUDE
5,357 kg
SAME HARNESS · 6× HIGHER AIR DENSITY
Air density at 3 km is 6× higher than at 18 km. Gross lift per dirigible rises from 454 kg to 2,861 kg. The stratospheric kit becomes a serious heavy lift platform at low altitude. A Land Rover. A shipping container.
4-DIRIGIBLE · 3 KM ALTITUDE
10,714 kg
SAME HARNESS · ZERO FUEL COST
10+ tonnes. A small excavator. A fully loaded shipping container. 10 tonnes of disaster relief supplies. Zero fuel cost. No road. No driver. DRAD-1 autonomous. Delivered to any GPS coordinate on Earth.
Zero Fuel Transport

No Road.
No Fuel.
No Driver.

A diesel truck spends $75,000–$90,000 per year in fuel alone. A helicopter cargo operation costs $500,000+ per year in fuel. A 4-dirigible harness carrying 10 tonnes costs $0 in fuel. Ever. It runs on solar power from the graphene envelope and water from a tank. Against a diesel truck fleet spending $300,000+ per year in fuel, the harness pays for itself in fuel savings in under one year. Then runs free for the rest of its operational life. No road. No fuel supply chain. No driver wages. No road damage. No toll. No CO₂.

🌍
Roadless Regions
Sub-Saharan Africa has 50 km paved road per 1,000 km² vs 340 km in Europe. Hundreds of millions beyond practical road access. Agricultural produce rots. Medical supplies cannot reach clinics. 4-dirigible harness at zero fuel cost — no road required. DRAD-1 autonomous delivery to any GPS coordinate.
⛏️
Remote Mining
Remote mines require purpose-built roads ($100M+) or helicopter resupply ($10,000+/tonne). Zero fuel cost changes the economics of remote resource extraction permanently. Mines currently uneconomic due to logistics become viable. Output transported to the nearest navigable water without road construction.
🆘
Disaster Relief
Road networks destroyed after earthquake, tsunami, flood. Helicopter resupply is expensive, weather-limited, and fuel-dependent. Dirigible requires no fuel supply chain. Deploys from LEO autonomously. 10 tonnes to any GPS coordinate regardless of ground infrastructure status.
🧊
Antarctic / Arctic
McMurdo, Arctic research stations, Greenland settlements resupplied by ship once per year. Dirigibles in continuous Antarctic summer daylight provide year-round cargo at zero fuel cost. No fuel supply chain to maintain. DRAD-1 autonomous. No crew at risk.
🏙️
Urban Last-Mile
Last-mile delivery is most expensive per km in urban logistics. 2-dirigible harness above city traffic: 5 tonnes, zero fuel, bypasses congestion entirely. Load beam lowers cargo to rooftop platform or street level. No loading bay. No ground dock. Cargo comes from above.
🏔️
Mountain Construction
Bridge sections, generator sets, cement, steel — delivered directly to the construction site regardless of terrain. 4-dirigible harness delivers 10 tonnes to any altitude up to 3 km. No access road required. No crane helicopter at $30,000/hour.

Solar Power.
Water.
Anywhere.

Manufactured at L4 from asteroid carbon. Deployed from LEO with no ground crew. Assembles itself on descent. Inflates on solar power in under an hour. Carries 10 tonnes across roadless terrain at zero fuel cost. Monitors the stratosphere for 24 hours a day. Cleans the air above megacities.

The same kit that monitors methane over Beijing carries relief supplies into a flooded valley with no road. The same envelope that generates lift at 18 km generates power for the entire system. The same water that provides ballast becomes the hydrogen that keeps it aloft. Everything is everything. Nothing is wasted.

Speculāris — On the cutting edge.

Lift. Monitor.
Deliver. Clean.

One kit. Four missions. Zero fuel. Indefinite endurance. Manufactured at L4 from asteroid carbon.
