Every number here was earned on a test stand.
Abyom's progress is measured in hardware — ignitions, hot fires, qualified structures — not announcements. Below is the record, and the dual-use defence capability that comes with it.
Engine test campaign
Hot-fire footage from the AbyoKalaM test series.
- 2020 – 2022
Space Research Program
The programme starts as research and outreach — building the team, the physics and the first institutional relationships.
- Space Research Program established
- First MoU with ISRO's Space Tutor programme
- 2023
Rocket Engine Testing Facility
Abyom moves from paper to hardware with its own containerised test facility, funded by its first external round.
- Rocket Engine Testing Facility built and commissioned
- Pre-Seed investment raised
- 2024
Injector validation
The core of the AbyoKalaM engine — the injector — is characterised run by run until the spray, mixing and stability are repeatable.
- Injector validation campaign completed
- Test campaign to validate pintle injection and atomization
- 2025
India's 1st commercial space infrastructure
Test infrastructure becomes a product: qualified facilities other organisations can book, backed by signed commercial intent.
- Built India's 1st commercial space infrastructure
- LOIs & MoUs signed for commercialisation
- 2026
BSE-2 Ethanol–GOX test bed
A dedicated ethanol–GOX bed takes the engine line to reusable hot-fire duty cycles.
- BSE-2 Ethanol–GOX test bed built
- Built and tested India's 1st reusable rocket engine
- 2027 · Design target
First flight window
Design target, not a committed date: structures, avionics and recovery systems integrate for vehicle-level qualification ahead of the Reusable Sounding Rocket's maiden flight.
- Stage & recovery qualification
- Sounding Rocket maiden flight — design target
A launch vehicle is also a strategic asset.
Propulsion
Compact, storable-fuel engines and test methodology transfer directly to tactical propulsion programmes.
Systems integration
Structures, propulsion and control integrated and qualified as one flight article.
Test & qualification
Instrumented ground testing methodology that de-risks hardware before it flies.
Responsive launch
Launch on demand — the ability to place a payload in orbit on national timelines, not someone else's manifest.
