Abyom Spacetech & Defence · India
Above and beyond
vyom.
Abyom Spacetech & Defence is building India's indigenous reusable launch vehicles — so orbit becomes a place the country can reach on demand, and within budget.
To place India as
the world's indigenous
reusable & reliable
space launch infrastructure.
Sustainable, cost-effective and cutting-edge reusable launch vehicle technologies that redefine access to space.
Launch on Demand · Launch within Budget
Launch on demand. Access to orbit should follow the mission's schedule, not a queue measured in years.
Launch within budget. Reusability is not a showpiece. It is the only honest path to cost that a research lab, a startup or a nation can afford.
Built in India, for India. Indigenous engines, structures and flight software — so sovereign access to space is never something we have to rent.
The next great launch nation
will speak in our accent.
India stands at the beginning of its own private space era — recognised by DST and IN-SPACe, guided by ISRO. Abyom is here to carry that story forward, and to make sure the next chapter is written in our own hand.
“I did not start Abyom to build a business.
I started it because someone from here
had to try.”
— Jainul Abedin · Founder & CEO, Abyom Spacetech & Defence
- Chapter I
A boy from Kushinagar
Jainul Abedin grows up in a small town in eastern Uttar Pradesh. The distance between Kushinagar and a launchpad is measured in more than kilometres — and he decides, early, to close it.
- Chapter II
The leap
Days before his final-semester exam of a master's in space science, he walks away from the paper and boards a train to Hyderabad. The mission cannot wait for a certificate.
- Chapter III
Government backing
Guided by mentors from ISRO. Recognised by the Department of Science & Technology and IN-SPACe. The country begins to notice.
- Chapter IV
First capital
Abyom closes its debut angel round. Belief becomes budget. A company that lived on paper begins to live in metal.
- Chapter V
Boeing BUILD 3.0
Abyom is named national winner of Boeing BUILD 3.0 at IIT Delhi — the first public confirmation that the mission is not a solo dream.
- Chapter VI
150+ engine tests
The team runs more than a hundred and fifty battleship engine tests on ethanol-fuelled propulsion. Every burn is a lesson. Every lesson earns its place in flight.
- Chapter VII
A reusable rocket
Abyom begins building what India has not yet built for itself — a fully reusable launch vehicle. Fly. Land. Fly again.
- Chapter VIII
Vision 2040
Reliable, affordable, sovereign access to space. Not for one company. For a country. For a generation that follows.
Reusable by
design, not retrofit.
One family of AbyoKalam engines, LOX/LNG propulsion and recoverable stages — engineered so the same hardware flies again, and the cost of reaching orbit falls with every flight.
Ethanol-fuelled engine
Battleship-tested. 150+ hot fires and counting.
Regeneratively cooled
Engineered for reuse, not for a single flight.
Composite structures
Lightweight airframe, laid up and cured in-house.
Avionics & GNC
Flight software written by the same hands that weld the tanks.
Recovery system
Because a rocket that lands is a rocket that flies twice.
Modular payload bay
Small-satellite class. Configurable per mission.
Three vehicles.
One doctrine — reuse.
From sub-orbital science to geostationary transfer, every Abyom vehicle is designed to fly, land and fly again. A single family of engines. A single answer to sovereign access.

Re-ignite. Launch.
Imagine with Abyom.
Five mission classes, one fleet. From near-space science to geostationary defence — every Abyom vehicle is built to serve more than one flight, and more than one purpose.
Orbital & Suborbital Launches
Frequent, low-cost deployment of satellites, micro-constellations and orbital assets — powering connectivity, earth observation and commercial space services.
Tactical Defence
Defence satellites into GEO for responsive space operations, and sovereign access to space for critical national missions.
Microgravity Experiments
Short-duration microgravity above the Kármán line — a platform for life sciences, fluid dynamics and material behaviour in space-like conditions.
Meteorological Missions
Advanced instruments to the upper atmosphere for high-altitude data, weather modelling, atmospheric profiling and calibration of climate instruments.
Test Rocket Engines
Static fire tests and performance evaluations at Abyom's Rocket Engine Test Facility — an accessible gateway for universities, startups and R&D teams.
We fail on the ground,
so we don't in the sky.
Abyom's Rocket Engine Test Facility — a containerised platform for engines up to 10 kN thrust, built in collaboration with PIEDS — has hosted 150+ battleship hot fires. Ethanol-fuelled. Instrumented to the millisecond. Every valve, every weld and every line of flight code earns its place through hours of testing — then, and only then, flight.
No one reaches orbit alone.
The institutions, mentors and backers standing behind India's indigenous reusable launch programme.
The people behind
the rocket.
A small, obsessed core building India's first fully reusable launch vehicle — engineers, doers, first-principles thinkers.
Standing on the shoulders of
India's finest.
Former ISRO directors, industry founders and strategic minds who sharpen every decision Abyom makes.
Proudly supported by
Institutions, mentors and partners
backing India's next launch chapter.
Ch. 10 · Vision 2040
Reliable.
Affordable.
Sovereign.
By 2040, Abyom intends to fly reusable Indian vehicles at cadence — carrying research, commerce and, one day, people. So that another child, in another small town, believes she can build a rocket too.
