Semi-Cryogenic Engine (SCE-200)

Next-Gen Kerosene/LOX Booster Engine for NGLV & LVM3

The SCE-200 is ISRO's 2,000 kN thrust semi-cryogenic rocket engine powered by ISRO-approved ISROENE (refined kerosene) and liquid oxygen (LOX). It will replace the liquid L110 core stage on LVM3 and power the Next Generation Launch Vehicle (NGLV Soorya).

Development History & Milestones

Developed by LPSC, cold flow tests and turbopump developmental trials were conducted at IPRC Mahendragiri in 2023–2024.

Core Space Applications

  • 1Boosting LVM3 payload capacity from 4 tonnes to 6 tonnes to GTO
  • 2Primary stage engine for NGLV modular boosters
  • 3Heavy space station module transportation

Frequently Asked Questions

What is a semi-cryogenic rocket engine?

A semi-cryogenic engine uses liquid oxygen at cryogenic temperatures (-183°C) combined with room-temperature refined kerosene (Isroene), providing high thrust without needing cryogenic liquid hydrogen.
