Storable Fuel

4,000

kg

Hydrazine on board. Storable. No boil-off. More than anything in its class.

Maximum Delta-V

KM/s

Range to traverse from low-Earth orbit through cislunar space and back.

On Station

15

years

Operational life designed for persistent presence in contested orbits.

Payload Ports

SLOTS

Mission-configurable. Sensors, communications, defense payloads, depot.

Fuel is the moat

Carries more fuel than anything in its class.

Four thousand kilograms of storable hydrazine. No boil-off. Mission-ready for the full operational life. Ranger can refuel other spacecraft and take fuel on, on its way to the next orbit.

01 Storable. Persistent.

Hydrazine on Ranger does not boil off. Mission-ready years after launch, ready when the picture changes.

02 Multi-mode propulsion.

One thruster. Two modes. High-thrust for speed, high-efficiency for range. Switched on demand. Brought in via the September 2025 Phase Four acquisition.

03 Refuel both directions.

Ranger passes fuel to other spacecraft and takes fuel on. The platform is the depot. Park in GEO, top up on the way to cislunar.

Range

From low-Earth to cislunar. In a single vehicle.

Most spacecraft optimize for one orbit. Ranger crosses every orbit the United States needs to hold, with fuel left for the return.

LEO

Low-Earth orbit.

200 to 2,000 km

Crowded, contested, and increasingly under threat. Ranger operates here, but does not stop here. It deploys, refuels, and ascends.

MEO

Medium-Earth orbit.

2,000 to 35,786 km

The transition layer. Few platforms operate here. Ranger crosses through with payloads to deploy, sensors to position, custody to maintain.

GEO

Geostationary orbit.

35,786 km

The high-value belt. Communications, surveillance, missile warning. Ranger holds station here, refuels other assets, and continues outward when the mission demands.

XGEO

Beyond geostationary.

Above 35,786 km

The under-defended frontier. Ranger goes forward to maintain custody of objects that move where no other platform can follow.

CISLUNAR

Cislunar space.

To 384,400 km

The Earth-Moon corridor. Ranger operates here under DARPA's LASSO program, advancing the characterization of lunar resources for the United States.

Mission-configurable

Five ports. Any payload. Any mission.

Ranger is payload-agnostic. Sensors, communications, defense systems, depot, partner spacecraft. Configured on the ground for the mission the customer is buying.

Sensors

Customer-defined. Ranger is payload-agnostic. Position the eye, anywhere above LEO.

Endurance

Fifteen years. On station.

Ranger is engineered for persistent presence. Deploy, hold position, reposition, stay. Refuel both directions. Outlast competitors that cannot stay long enough to matter.

Designed for fifteen-year operational life in contested orbits.
Refuels other spacecraft and takes fuel on. The platform is the depot.
Maintains custody of objects that move. Where competitors cannot follow.
Reconfigurable on the ground. Persistent in orbit. Mission-flexible across the life.
