SpaceFields

SpaceFields is a Bengaluru-based, IISc-incubated propulsion startup founded in 2021 by Apurwa Masook, Rounak Agrawal, and Sudarshan Samal. It develops solid-fuel rocket propulsion systems for UAVs, rockets, and spacecraft, and hot-fire tested what it calls India's first aerospike rocket engine in 2024 at Challakere, Karnataka. The company has raised a roughly $5M Pre-Series A round and won four iDEX defence contracts.

AeroSpike Rocket Engine

development
rocket engine

Solid-propellant aerospike rocket engine, hot-fire tested as India's first aerospike engine at Challakere; peak thrust ~13.42 kN, total impulse ~32,624 Ns, HTPB-based composite propellant with a Ti-6Al-4V structure.

Solid rocket propulsion systems

development
propulsion

Custom solid-fuel rocket propulsion systems for UAVs, rockets, and spacecraft; backed by in-house patents and four iDEX defence-ministry contracts.

Key Challenges

Scaling from sub-15 kN test-article engines to flight-qualified, higher-thrust production systems.Securing key regulatory certifications and scaling manufacturing.Competing against larger, better-capitalised Indian propulsion and launch players in a defence/dual-use market.
