The SCE-200 (also referred as Semi-Cryogenic Engine-200) is a 2 MN thrust class liquid rocket engine, being developed to power Indian Space Research Organisation's (ISRO) existing LVM3 and upcoming heavy and super heavy-lift launch vehicles.

[8][9][10][11][12] The engine in September 2019 reportedly had become ready to begin testing in Ukraine and enter service no earlier than 2022.

The engine blueprints supposedly transferred by Ukraine to India, have been identified as the RD-810 which in turn is a variant of Russian RD-120.

The engine is a part of the ₹1,800 crore (US$210 million) semi-cryogenic launch vehicle program, which would be capable of placing 6,000–10,000 kilograms (13,000–22,000 lb) in GTO.
