H2DRAGON ROCKET
THE LAUNCH BOTTLENECK IS THE OPPORTUNITY

HYDROGENDRAGONROCKET

The space economy is racing toward a trillion-dollar decade — held back by one thing: the cost of reaching orbit. We are building the platform that breaks it.

Why Cheap Launch Changes Everything

One bottleneck sits under
every space business.

Satellites are no longer the hard part — getting them to orbit is. Launch is expensive, slow, and controlled by a handful of providers whose costs have stopped falling. Every constellation, every new service, every ambition in orbit is throttled by the same constraint.

The last generation proved the prize is real: the companies that lowered launch cost built the most valuable space businesses of the era — and the capital that backed them is now looking for what comes next. The incumbents carry the sunk cost of the systems they built. The opportunity is not to compete inside that generation. It is to leapfrog it.

The bottleneck
Demand outruns supply
Launch cost has stopped falling; demand has not stopped rising. Tens of thousands of satellites are filed against launch capacity that cannot meet them.
The prize
A trillion-dollar decade
A space economy heading toward $1.8tn by 2035 (McKinsey/WEF); the satellite market alone forecast to grow sevenfold (Goldman Sachs Research). Cheap launch is the key that unlocks it.
The leapfrog
Built for what's next
A reusable, hydrogen-powered platform built for the economics the next generation needs — not a refinement of the last one.
Where the Technology Stands

Beyond concept —
key subsystems built and tested.

This is not a paper idea. The core subsystems at the heart of the platform — including the composite cryogenic tanks and the propulsion and energy systems — are built and tested, well beyond the concept stage. What remains is to integrate them into a complete vehicle and prove the launch economics in flight.

We are direct about the distinction: the key building blocks are demonstrated; the integrated single-stage system will be proven in flight. That demonstration is the milestone that lifts the whole platform — and it is what we are building toward. The market is validated. The foundations are built and tested. The demonstration is the next step — and the reason this is the moment to engage.

Detailed technology-readiness information is shared with qualified partners.

The Enabling Breakthrough

The tank that makes
single stage possible.

Single-stage-to-orbit asks for a contradiction — a vehicle light enough to reach orbit on one stage, yet strong enough to survive re-entry and fly again. Conventional metal tanks cannot resolve it. H2Dragon's non-metallic composite cryogenic tanks are the resolution: stronger than steel by weight, light enough to make a reusable single-stage stack physically possible. This is the core the whole platform is built around.

TRL 9 — live and operational

The tank technology is at Technology Readiness Level 9 — proven in operation, not a laboratory prototype. It is the most mature element of the platform.

World-record LH₂ storage

The tanks hold a world record for liquid-hydrogen storage — a benchmark for what the material can do at scale.

Lloyd's Register certified

The composite material carries Lloyd's Register certification — independent validation from a recognised classification body.

At the Heart of the Platform

The engine that
makes it possible.

Cheap access to orbit rests on propulsion. At the core of the platform is a rotating detonation engine (RDE) — a compact, high-efficiency design that extracts more energy from the same fuel than a conventional rocket, in a lighter, simpler package.

Detonation, not deflagration

The RDE releases energy through a continuous detonation wave — a fundamentally more efficient combustion process than the steady burn of a conventional engine.

Tested to Mach 10

The engine has been tested to Mach 10, with an operating target of hypersonic cruise around Mach 6 — among the most advanced elements of the platform.

One engine, two futures

The same propulsion core powers the launch platform and an emerging second application: ultra-fast point-to-point transport.

What Cheap Launch Unlocks

One platform.
Several trillion-dollar markets.

Break the launch bottleneck and you don't open one business — you open the door to every business that depends on affordable access to orbit. Each of these begins from the same launch capability. Direct-to-cell is the clearest proof of why launch cost is the lever: its entire economics hinge on deploying and replenishing satellites cheaply.

Near-term

Satellite Launch

Small-satellite & constellation access

On-demand launch for small satellites and constellations — built for operators who need to reach orbit without the cost and the queue of conventional rideshare.

Direct-to-device — devices connecting straight to satellites
Market we enable

Direct-to-Device

The next wave of connectivity

Devices talking straight to satellites — no tower, no dish. Phones, IoT sensors, wearables and vehicles, connected anywhere on Earth. It is the largest, most launch-hungry market in space, and its economics hinge on deploying and replenishing satellites cheaply — exactly what our launch platform exists to do. We are seeking partners, collaborators and operators to build this market on top of it.

Direct-to-Cell Device

Our specific offer within direct-to-device

Within that market, our group has developed a concrete offer: a working prototype handheld terminal — roughly half the size of a credit card — that pairs with everyday wireless earphones to bring satellite voice and data to an ordinary phone. It is designed to operate with Starry Sea, a 350-satellite constellation architecture developed in-house. The terminal is built; the constellation is in development; regulatory and spectrum access is being pursued.

The Network · Starry Sea 星辰大海

The constellation behind
direct-to-device.

Direct-to-device is only as real as the network above it. Starry Sea is that network — a worked, detailed satellite-communications architecture, not a sketch: 350 satellites, regenerative on-board processing, and a single-gateway ground return, engineered end to end.

40
Sub-channels
The 0.8 GHz user band divided into 40 × 20 MHz sub-channels, each carrying 100 orthogonal-code users.
40,000
Users per satellite
Ten user-service payloads, 4,000 users each — online simultaneously on a single spacecraft.
350
Satellites
The full constellation, with a detailed design covering payload, link budgets and frequency planning.

Hybrid user link

A combined OFDM + CDMA user link divides the band into 40 sub-channels, each carrying 100 orthogonal-code users — 4,000 users per payload, ten payloads per satellite.

Regenerative on-board processing

Rather than a bent-pipe relay, each satellite recovers the user database on board and routes traffic through an on-board switch to a dedicated aggregation payload.

Single-gateway return

The aggregation payload combines every beam, frames and codes it, and returns it to one ground gateway per constellation — a clean, centralised downlink.

Full modulation, link-budget and frequency-planning detail is shared with qualified partners.

Application · Wildfire Intelligence from Orbit

The Flame Model.

Proven approach

A proprietary wildfire-detection capability — our flagship mission, demonstrating the full platform from launch to live data, validated in the field.

Wildfire-detection technology — illustrative concept

The wildfire-detection landscape — illustrative concept (computer-generated illustration). Shown for context; not a depiction of H2Dragon’s specific system.

The model

A proprietary detection model that identifies genuine fire signatures early and rejects false alarms — the capability buyers actually pay for, validated in the field.

The method

A collection method that gathers and fuses thermal data fast enough to act on — turning a raw signal into an alert while a fire is still small.

The launch

The same low-cost platform that puts and keeps the constellation in orbit — the economic edge over detection-only competitors.

The moat is the combination

No single element is unique. Together they are hard to replicate — a competitor would need to match a model, a global posture, and a launch capability at once.

AI model
earlier, cleaner detection
+
Global coverage
the lane WUI players can’t reach
+
Launch economics
cheap refresh a software rival can’t copy

Each alone is matchable. The stack is the defence.

The detection model is also available as a licensable capability in its own right, independent of the constellation.
