SCE-200

The SCE-200 which was recently renamed by ISRO as, SE-2000 (also referred as Semi-Cryogenic Engine-2000) is a 2 <a href="/facts/Newton_(unit)/Ral9XgNl">MN</a> thrust class liquid rocket engine, being developed to power <a href="/facts/ISRO/CdAoFQTL">Indian Space Research Organisation</a>'s (ISRO) existing <a href="/facts/LVM3/BHqVWNrW">LVM3</a> and upcoming <a href="/facts/Heavy-lift_launch_vehicle/IUfQAwcI">heavy</a> and <a href="/facts/Super_heavy-lift_launch_vehicle/JSwbocv8">super heavy-lift launch vehicles</a>. It is being developed by the <a href="/facts/Liquid_Propulsion_Systems_Centre/WJsn3f3P">Liquid Propulsion Systems Centre</a> (LPSC) of ISRO, and is expected to have first flight in 2020s.
Burning <a href="/facts/Liquid_oxygen/qnI0KDTb">liquid oxygen</a> (LOX) and <a href="/facts/RP-1/wDI7vNdu">RP-1</a> kerosene in an oxidizer-rich <a href="/facts/Staged_combustion_cycle/eINPGPr5">staged combustion cycle</a>, the engine will boost payload capacity of LVM3 replacing current L110 stage powered by 2 <a href="/facts/Vikas_(rocket_engine)/lSKcTgRE">Vikas engines</a>. It is also expected to power ISRO's upcoming <a href="/facts/Next_Generation_Launch_Vehicle/jSAGVXkP">Next Generation Launch Vehicle</a> (NGLV) rockets (previously planned as <a href="/facts/Unified_Launch_Vehicle/jSAGVXkP">ULV</a>) as well as ISRO's future reusable rockets based on <a href="/facts/RLV_Technology_Demonstration_Programme/aHQMPH1P">RLV technology demonstrations</a>.
The engine in September 2019 reportedly had become ready to begin testing in Ukraine and enter service no earlier than 2022. The use of engine of <a href="/facts/Gaganyaan/RURHEapJ">India's first human spaceflight</a>, hence was ruled out by ISRO. By November 2022, SE-2000 had neared completion of its qualification tests. The Semi-Cryogenic Engine and Stage Test Facility at the <a href="/facts/ISRO_Propulsion_Complex/0pRCtBJ5">ISRO Propulsion Complex</a> Mahendergiri was preparing for ground tests now that the SE-2000 had reached the final stages of development.
