Indian rocket startup Agnikul completes static fire test of three-engine cluster
The Indian rocket startup Agnikul has now released a video of a 40-second static fire test of three-engine cluster it hopes to use on its Agnibaan orbital rocket.
The engines, powered by electric motor-driven pumps, were designed and manufactured in-house at Agnikul’s Rocket Factory-1. All three were fully 3D-printed as single-piece hardware units, reflecting the startup’s focus on advanced manufacturing and indigenous engineering.
Co-founder and chief executive Srinath Ravichandran said that increasing the number of engines improves rocket performance and that a three-engine system is required for commercial missions. The clustered test involved calibrating six pumps and six motors and fine-tuning six independent speed control algorithms to function in synchronisation. The goal was to achieve uniform startup, steady-state operation and shutdown performance across all three engines, a technically complex process given the precision required in semi-cryogenic propulsion systems.
The company has completed one suborbital test launch in May 2024, and in September 2025 said its orbital rocket’s first stage will land vertically and be reused.
Agnikul however has not released any schedule for launch, and based on this static fire test appears years from a first launch. It is making progress, but slowly. At the same time, it says it has raised $500 million in private investment capital, giving it the resources to build the rocket.
Based on testing and published progress, Agnikul appears to be trailing India’s other rocket startup Skyroot, though this could change in the coming year.
