AgniKul Cosmos, a space technology company developing launch vehicles and propulsion systems, has test fired three semi-cryogenic rocket engines simultaneously in a clustered configuration for 22.5 seconds. The engines, designed and manufactured in-house, were produced as single pieces of hardware using three-dimensional printing at the company’s AgniKul Cosmos Rocket Factory – 1.
Srinath Ravichandran, Co-Founder and Chief Executive Officer at AgniKul, said the three engines were powered by electric motor-driven pumps and were tested together as a cluster. He said the test involved calibrating six pumps and six motors and tuning six speed control algorithms to operate in synchronisation to achieve uniform startup, steady-state and shutdown performance across the system.
Ravichandran stated that, to the company’s knowledge, this was the first time in India that such a clustered test had been conducted using semi-cryogenic engines. He added that all propulsion systems developed by the company use electric motor-driven pump architecture and that the company’s activities are supported by the Indian Space Research Organisation (ISRO) and the Indian National Space Promotion and Authorisation Centre (IN-SPACe).
The clustered test follows a series of recent milestones. In May 2025, the company successfully test fired India’s first electric motor-driven semi-cryogenic engine. In September 2025, it inaugurated a Large Format Additive Manufacturing (LFAM) facility to enable three-dimensional printing of single-piece aerospace components up to one metre tall. In early 2026, AgniKul also announced a partnership with Neevcloud to build and launch a proof-of-concept space-based artificial intelligence (AI) data centre aboard its Agnibaan launch vehicle.
To support its development plans, the company raised INR 1.5 billion, equivalent to approximately USD 17 million, in a Series C funding round in November 2025. The round included equity and debt financing from investors including Advenza Global, Atharva Green Ecotech, HDFC Bank and Pratithi Investments, valuing the company at over USD 500 million.
Earlier, in October 2023, AgniKul secured USD 26.7 million in a Series B funding round. Since its inception in 2017, the company has raised over USD 70 million in total funding. The latest capital is earmarked for scaling production units, expanding its integrated space campus and advancing its reusable launch architecture.
AgniKul Cosmos designs and manufactures launch vehicles and propulsion systems, including semi-cryogenic engines produced as single-piece hardware using additive manufacturing technologies.
