Reusable Launch Systems
Who We Are
Building India's pathway to fully reusable launch vehicles through advanced propulsion and landing innovation.
Cosmo Crawler is on a mission to develop a fully reusable launch vehicle. Our journey began with designing and cold-testing a small liquid rocket engine — powered by next-generation propellants for cleaner, more efficient combustion.
Core Capabilities
Three pillars driving the next era of affordable, reliable space transportation.
Designing launch systems built for multiple flights — dramatically lowering per-kilogram launch costs and enabling sustainable space operations.
Our hybrid landing approach combines proven recovery methods with novel control systems to reduce landing risk and improve vehicle turnaround time.
Advanced liquid rocket engines using next-generation propellants, electric pump feed systems, and additive manufacturing for rapid iteration.
R&D Milestone
Our first engine prototype is fully 3D-printed in a super aluminum-silicon alloy (Al-Si) — an aerospace-grade material. Assembled with spray pump motors for initial testing, it underwent cold testing with ignition to characterize dynamic combustion properties.
The engine operates on next-generation rocket propellants and is driven by an electric pump feed system — validating our core propulsion architecture before scaling to full thrust.
Live Propulsion Test

Propulsion Product
The CAIMAN 2000 is a fully 3D-printed liquid rocket engine in the micro-thrust class. It features continuous restart capability without thrust degradation — a critical requirement for precision maneuvering and landing operations.
