Zephyr lifts-off from its launchpad
Zephyr gains altitude and speed
First stage engines cut-off (MECO) and stages 1 & 2 separation. Stage 1 falls back. Second stage engine ignition
The fairing separates and falls back, exposing the payloads to the vacuum of space
Second stage engine cut-off (SECO). The launcher is set on a transfer orbit
The launcher rises in altitude from perigee to apogee of the transfer orbit
The Auxiliary Propulsion System (APS) is used to raise the perigee and circularize the orbit
The payloads are separated from the launcher and set on their desired orbit
The Auxiliary Propulsion System is used again to lower the perigee and set the launcher on a course to deorbit
The second stage burns in the atmosphere
The Navier engines, fully designed in-house and 3D-printed, drive both stages of the rocket, delivering high performance.
They operate on the LOx-RP1 propellant combination, a proven and reliable choice that has powered countless space missions, ensuring efficiency, stability, and trust in every launch.
Latitude’s in-house turbomachinery expertise is now a strategic advantage, allowing us to optimize performance, enhance flexibility, and adapt to a variety of SmallSat missions.
With a versatile orbit reach — from 3.5° to 100.5° inclination — Zephyr ensures that SmallSats reach their destinations with pinpoint accuracy.
Our Titan Research & Test site, located south of Reims at XCR Airport, is a cornerstone of this journey. This secure facility allows us to independently and rigorously test hardware, refine our technology, and push the limits of performance without compromise.
By conducting these critical tests in-house, conceiving and building our tests means, we ensure Zephyr evolves with reliability and resilience, paving the way for a new era of dedicated small satellite launches.
Each trial brings us closer to orbit, transforming vision into reality—one test at a time.
Zephyr’s industrialization is built on advanced manufacturing and full-scale assembly in our future Reims production plant. Using cutting-edge techniques and a rigorous design-to-cost approach, we ensure efficiency, scalability, and reliability.
Every rocket is crafted for mass production, making Zephyr a high-performance launcher that redefines how SmallSats access space—efficient, repeatable, and built for the future.

Zephyr has a SmallSats and SmallVehicles-optimized fairing allowing a wide range of payload configurations, from single-launch MicroSats, to orbital Capsules and CubeSat or MicroSats constellations.
The Payload Support has been designed so that it can be configured for a variety of types and numbers of payloads. This allows a wide variety of satellite types to be launched and deployed by Zephyr.

Zephyr's second stage houses 2 propulsion systems maximizing efficency and thrust for each mission.
First, the Navier vacuum engine allowing the orbital injection of the second stage. Second, the APS allowing for the circularization and deorbitation of Zephyr as well as attitude control of Zephyr in between the second stage firing and the end of the mission.

Zephyr’s first stage ensures the initial boost of the second stage in the first phase of launch.
The first stage is equipped with a cluster of seven in-house designed Navier Sea Level engines, propelled by a turbopump with a mixture of LOX and RP-1 allowing Zephyr to produce thrust, liftoff and escape Earth’s atmosphere with ease.
