Abyom SpaceTech & Defence

As we progress towards our Flight Ready Engine (FRE) & HOPE Vehicle development program, we have successfully executed the BSE-II engine hot fire test campaign. This phase focused on validating key reusability technologies - including injection, throttling, and ignition operating at ~12 bar chamber pressure and temperatures exceeding 2200°C. Building on our BSE-I campaign, where we demonstrated India’s first Pintle Injection mechanism, BSE-II takes us a step further with stable combustion under blow-down feed conditions, refined impingement mixing architecture, and expected plume behavior, including Mach diamond formation during firing. The entire testing stack - engine, test bench, control systems, test instrumentation and the DAQ system — has been fully designed and developed in-house by Team Abyom SpaceTech & Defence. This campaign successfully validated combustion stability, chamber pressure targets, and overall integrated system performance. Each step like this strengthens not just our propulsion systems, but also the ecosystem required to build reliable, reusable launch capabilities - contributing to India’s growing strength in Space and Defence. Small engine. Big step forward.

Hyderabad-based Abyom SpaceTech & Defence Pvt. Ltd. has completed the hot-fire test of its BSE-II rocket engine, a key component of its upcoming HOPE (Highly Optimised Propulsion Engineering) vehicle. Founded by Jainul Abedin, Abyom is an emerging spacetech startup headquartered at the BITS Pilani Hyderabad campus. The company is focused on building a full-stack space infrastructure ecosystem, with core emphasis on reusable launch vehicles powered by re-ignitable and throttleable cryogenic engines. Its long-term vision is to enable frequent, affordable, and on-demand access to space, catering to both commercial and defence applications. Abyom’s product portfolio spans multiple verticals, including small, medium, and sounding reusable launch vehicles, along with rocket engine test facilities designed for performance validation and R&D. These systems are being developed to support missions ranging from satellite deployment in Low Earth Orbit (LEO) to deep-space and defence-oriented applications. The recent BSE-II engine test marks a crucial step in the company’s Flight Ready Engine (FRE) program and the broader HOPE vehicle roadmap. According to reports, the test successfully validated several critical propulsion parameters, including precision injection systems, dynamic throttling, and reliable ignition sequences under extreme conditions. The engine operated at around 12 bar chamber pressure and temperatures exceeding 2200°C, closely simulating real-flight environments. Notably, the test demonstrated stable combustion under blow-down feed conditions, a technically demanding scenario that mimics actual propellant behaviour during flight. Engineers also optimised fuel-oxidiser mixing to improve efficiency and minimise thermal stress, which are key requirements for reusable rocket systems. The observation of expected plume characteristics, including Mach diamond formations, further validated the engine’s supersonic exhaust performance. #startuppedia #startupjourney #startupbusiness

@vadapallichaitu We’ll be revamping our website soon and will include all the details there. Thanks for asking!

@AbyomSpaceTech How come there isn’t single page dedicated to BSE engine specifications

@Arjun49431 Yes, it is our Vertical Take-Off Vertical Landing (VTVL) Reusable Rocket prototype!

@AbyomSpaceTech Hey @AbyomSpaceTech can we get some ideas about Hope vehicle What is it , a TD Or a Sounding rocket Or something else

@NewsIADN Thanks for sharing!

Hyderabad-based #AbyomSpaceTech has successfully tested it's BSE-II Engine for HOPE Vehicle.

It was truly a humbling experience to be invited for dinner & interaction hosted by Hon’ble Prime Minister Shri @narendramodi Ji alongside H.E. President @EmmanuelMacron of the French Republic. Being recognised and selected among the Top 5 DeepTech startups across the country in this program and standing in the same room with 30 distinguished Indo-French diplomatic delegates, along with Hon’ble PM, President Macron, Chief Minister @Dev_Fadnavis , Deputy CM @mieknathshinde , Hon’ble External Affairs Minister @DrSJaishankar, National Security Advisor Shri Ajit Doval, and esteemed IIT Directors was a moment of deep reflection. The evening commenced with the launch of the India–France Year of Innovation at The @Tajmahalpalace, followed by an inspiring dinner dialogue, and concluded with a breathtaking large-scale video mapping and lighting showcase at the Gateway of India, transforming it into a living canvas celebrating innovation, shared values, and cultural heritage. India and France share a strong and historic partnership in aerospace and strategic technologies. As a DeepTech founder building in the space and defence sector, I strongly believe this collaboration will unlock new frontiers of joint innovation, research, and global impact. Grateful to be part of this defining moment in India’s technology diplomacy journey. @AbyomSpaceTech @startupindia @IndiaDST @DPIITGoI @investindia @NITIAayog @GoI_MeitY @iitbombay @iitmadras @FranceinIndia #IndiaFrance #DeepTech #SpaceTech #StartupIndia #Innovation #Aerospace #Abyom #AbyomSpaceTech

Founded in 2020 by Jainul Abedin, Abyom SpaceTech and Defence is developing reusable rocket technology to address cost barriers in India’s launch ecosystem. He used his national fellowship to fund his initial research, identifying India’s lack of reusable launch technology as a critical, cost-prohibitive gap. @AbyomSpaceTech forbesindia.com/lists/30-under…

Hi, thank you for your query. This solid rocket motor test was conducted under an Industry–Academia collaboration, where we supported the IIT Bombay Rocket Team in the development and testing of their solid rocket motor for Rocketery Competition. The testing was carried out at Abyom’s plug-and-play commercial rocket engine testing facility, with the objective of making advanced space infrastructure accessible to the next generation of innovators. We remain fully aligned with and focused on our core vision of Reusability. Hope this clarifies.

@AbyomSpaceTech @iitbombay @IITBRocketTeam @IndiaDST @ANRFIndia @startupindia Isn’t abyom announced reusable LV, how does solid motor fit in all this?

Last month, we successfully conducted dual M-Class solid rocket motor tests, achieving a peak chamber pressure of 21 bar and a combined total impulse of ~8,400 Ns across both firings. Test-1 achieved a Peak thrust of 2,900 N, and Test-2: a peak thrust of 3,000 N. These results mark a strong validation of our in-house design, manufacturing, and test infrastructure, reinforcing our readiness for higher-performance propulsion systems. Congratulations to @iitbombay Rocket Team for competing in the 10k SRAD category at IREC 2026. We’re proud to support industry and academia pushing the boundaries of indigenous aerospace innovation. Our Rocket Engine Test Facility is now fully operational and open to external partners, enabling academia, startups, and industry to accelerate development through reliable, commercial-grade testing. As we move into 2026, we’re gearing up for multiple milestones focused on #Reusability, scale-up, and commercialization of critical Space & Defence technologies—building the backbone for India’s next generation of launch systems. #Abyom #AbyomSpaceTech #DeepTech #RocketPropulsion #ReusableRockets #DefenceTech #AerospaceEngineering #MakeInIndia
