Human-rated Vikas engine ISRO: Godrej Aerospace delivers L110 stage engine for India’s Gaganyaan mission, marking a major milestone in crewed spaceflight and Make in India space initiatives.
Godrej Delivers Human-Rated Vikas Engine to ISRO for Gaganyaan Mission
India has achieved a significant milestone in its space ambitions as Godrej Aerospace recently delivered the first human-rated L110 Vikas engine to the Indian Space Research Organisation (ISRO). This engine will be used in the core stage of the LVM‑3 (also called LVM3‑G or Human‑Rated Launch Vehicle), which is the launch vehicle selected for the Gaganyaan mission — India’s first manned spaceflight.
What Makes the Human-Rated Vikas Engine Special
The “human-rated” designation means that this version of the Vikas engine has been modified and rigorously tested to meet much higher standards for safety, reliability, and performance — far beyond what is typical for uncrewed missions. These enhancements include redundant systems, high fault tolerance, and extensive ground testing to ensure that in case of any issue during flight, astronaut safety is not compromised.
Role in the Gaganyaan Mission
The L110 stage of the LVM‑3 rocket, powered by this Vikas engine, will provide the core thrust during ascent. This makes it a critical component, as stable and reliable thrust is essential when sending humans into orbit. The Gaganyaan mission itself is designed to carry a three-member Indian crew into low Earth orbit for up to three days.According to current timelines:
- The first uncrewed test flight is expected around early 2026.
- The crewed mission is targeted for 2027, making use of fully indigenous systems.
Godrej Aerospace: A Trusted Partner for ISRO
Godrej Aerospace has been a long-term collaborator with ISRO, contributing to major programs over four decades.Their past work includes manufacturing engines and components for PSLV, GSLV, LVM‑3, and contributions to missions like Chandrayaan, Mangalyaan, and the NASA-ISRO NISAR satellite.This delivery of the human-rated Vikas engine underscores not only Godrej’s engineering prowess but also India’s growing self-reliance under its “Make in India” vision in space capabilities.
Static Facts for Exam Preparation

Why This News Is Important
Boosts India’s Human Spaceflight Ambitions
This delivery is a major step forward in the Gaganyaan programme, which aims to make India one of the few nations capable of independently sending humans to space. By supplying a human-rated engine, Godrej Aerospace strengthens ISRO’s capacity to launch astronauts safely, thereby advancing the national goal of human spaceflight.
Reinforces “Atmanirbhar Bharat” in Space Tech
The fact that the engine is indigenously manufactured by an Indian company highlights the success of India’s push for self-reliance in space technologies. This aligns with the broader national strategy of reducing dependence on foreign suppliers for critical mission phases.
Strengthens Public-Private Partnership
Godrej Aerospace’s role in this mission reflects growing collaboration between ISRO and the Indian private sector. Such partnerships are crucial for capacity building, technology transfer, and accelerating the pace of space exploration and innovation.
Historical Context
To appreciate the significance of this achievement, it helps to understand some background:
- Vikas Engine Legacy: The Vikas engine has been a workhorse for ISRO for decades. Originally based on the French Viking engine, it has powered various stages of Indian launch vehicles like PSLV, GSLV, and LVM-3.
- Gaganyaan Programme Origins: Announced several years ago, the Gaganyaan mission is India’s first manned spaceflight project. The plan involves uncrewed test flights before launching humans, reflecting a cautious, phased approach to ensure safety and reliability.
- Human Rating Process: “Human rating” an engine is not trivial — it requires extra redundancy, fault tolerance, and extensive testing. ISRO and its partners have carried out a long validation campaign to certify the L110 Vikas engine for crewed flight.
- India’s Growing Role in Space: This marks not just a technical milestone but also a symbolic one: India is increasingly demonstrating its ability to design, build, and certify mission-critical space hardware domestically. It strengthens India’s global posture in the space domain.
