- This major milestone has been accomplished at the Solar Industries Propulsion Test Facility in Nagpur, Maharashtra using an indigenously developed mobile cryogenic engine test pad.
- Earlier in November 2022, Sky root launched India's first privately developed rocket Vikram-S, which made the firm the first Indian private company to send a rocket into space.
- Dhawan II:
- Sky root's Dhawan cryogenic engine line is named in honor of renowned Indian rocket scientist Satish Dhawan. Dhawan II is based on Sky root's first privately developed full-cryogenic rocket engine - Dhawan I, which was successfully flight tested on 21 November. It is completely indigenously manufactured and uses a super alloy for the 3D printing engine, which has reduced the manufacturing time by up to 95%. It will use Liquefied Natural Gas (LNG) and Liquid Oxygen (LoX) as propellants.
