Our Launch Vehicle Programme

Speck

Reusable Launch Vehicle Demonstrator

Speck is a small-scale reusable launch vehicle demonstrator developed to validate core technologies required for propulsive vertical landing and rapid vehicle reuse. The programme focuses on iterative flight testing of guidance, navigation, and control systems; propulsion performance; and structural reusability under repeated flight loads.

Project Zero

Full Scale Reusable Orbital Launch Vehicle

Project Zero is QUNIX's medium-lift reusable launch vehicle, designed to deliver payloads to low Earth orbit and sun-synchronous orbit with a fully reusable first stage. Named after the Tamil word for eagle, Project Zero represents the next step after Speck — scaling proven reusability into an operational orbital system at competitive cost-per-kg. Building on propulsive reusability validated through Speck, Project Zero is designed to carry payloads to low Earth orbit with a recoverable first stage. All specifications are preliminary and will be updated as the design matures.
