Skyroot Aerospace, a Hyderabad-based space technology startup, has successfully test-fired the Dhawan-1 engine and is planning to launch Vikram-1 and Vikram-2 launch vehicles in a few years. 

Dhawan-1 is India’s first privately developed, fully cryogenic rocket engine. It runs on two high-performance rocket propellants — liquid natural gas (LNG) and liquid oxygen (LoX). 

The engine was developed using 3D printing with a superalloy.
