We are building the capability behind rapid access to space.

BUILT FOR ORBIT

MAKE ACCESS TO ORBIT FASTER.
MORE DEPENDABLE, AND ON YOUR TERMS.

We are building reusable rockets around a different constraint: how quickly a mission can move from requirement to flight. Vehicles, engines, ground systems, test operations and manufacturing capability are developed together so launch is not treated as a bespoke campaign, but as a repeatable service built for mission tempo.

METRICS

Recorded development outputs across propulsion testing, performance measurement, and in-house manufacturing.

STATIC FIRES

HOT-FIRE TESTS COMPLETED

The number of hot fire caimpaigns undertaken to date across various propulsion system designs.

PROPULSION INNOVATION

PERFORMANCE GAIN

The observed increase in Specific Impulse compared to a standard "baseline" system configuration. *Time Averaged

MANUFACTURING CYCLE
<00 hrs
FROM CONCEPT TO COMPOSITE

The average amount of time to progress from concept to produced component using in-house automated techniques.

Building for missions that move at operational speed.

HOW WE BUILD

Our build model is simple: stay lean, own the bottlenecks, prove decisions in hardware, and turn every cycle into faster launch capability.

First Principles
Nothing inherited by default

We keep proven designs where they earn their place, and rebuild them where the process demands better. Every choice is made to optimise not only performance, but for automation in manufacturing.

Hardware Tempo
Build, Test, Learn, Repeat

When progress is slowed by a supplier, process, model or machine, we build the capability ourselves. Simulation tools, test rigs, manufacturing methods and ground systems are treated as leverage, not overhead.

Mission Consequence
Built for missions that cannot wait

Launch capability has to match the tempo of the missions it serves. We are engineering toward systems that can be prepared, operated and repeated with urgency.

Accelerate Progress
Integrate Early

We work with startups, researchers and hardware teams before orbit becomes the requirement, giving payloads a path to real flight conditions while our own test cadence keeps accelerating.

LOOKING TO TEST?

BUILD IT. FLY IT. LEARN FASTER.

Need more than ground-based shake tables or expensive parabolic flights can offer? Selected Antares sounding rocket missions are open to teams looking to validate hardware, fly experiments, or expose payloads to real ascent loads, vibration, recovery conditions and microgravity environments; at a price point built to make flight testing more accessible.
