D-Propulse Aerospace has secured ₹25 crore in a funding round led by IAN Alpha Fund to advance its rotating detonation engine technology. D-Propulse Aerospace has raised ₹25 crore in a funding round led by IAN Alpha Fund.
The fresh capital will be used to support product development and early testing of the company’s propulsion systems, it said in a statement on Wednesday.
“We have entered an era where speed is the new stealth. Defence budgets across the major power centres of the world are pivoting in recognition of this new reality. Our vision is to ensure that India is fully equipped to not merely navigate but potentially dominate this emerging era of high-supersonic and hypersonic systems,” said Saurav Jha, founder & CEO, D-Propulse Aerospace.
The firm is developing a rotating detonation engine-based propulsion systems, a technology that differs from traditional jet engines by eliminating moving parts in the combustion process.
According to the company, this enables simpler manufacturing with potential applications across high-speed aerospace platforms.
Founded in 2025, D-Propulse Aerospace aims to address gaps in advanced aero-propulsion capabilities, particularly for high-speed defence and aerospace systems.
“Affordability is the real unlock if India is to move from a few exquisite platforms to true scale. We see D-Propulse’s team that understands both the physics and the strategic context, and are delighted to back them as a long-term partner in building this for India,” said Rajnish Kapur, managing partner, IAN Alpha Fund.
The startup is led by Jha, along with co-founder and CTO Dr. V. Ramanujachari, a former senior scientist at the Defence Research and Development Organisation.
The capital will also be allocated to expand the engineering team, strengthen computing and simulation capabilities, and set up testing infrastructure.
