The SCE-200 is an Indian liquid-fuel rocket engine burning LOX and kerosene in a oxidizer-rich staged combustion cycle.[3] It is being developed by the Liquid Propulsion Systems Centre, a subsidiary of India's space agency ISRO, to power the future heavy-lift Unified Launch Vehicle (ULV) and Reusable Launch Vehicle (RLV) being planned by ISRO[5]. But before that it will be tested with GSLV Mk III by replacing L110 (powered by old Vikas engine) stage to SC200.[6][7][8]

The primary goal of ISRO will be bringing in a new family of launch vehicles called ULV (Unified Launch Vehicle) by replacing currently operational PSLV, GSLV and GSLV Mk III. The ULV (Unified Launch Vehicle) marks the renunciation of India for N2O4/UDMH as propellant for space launch vehicle systems.

History

On June 2, 2005, India and Ukraine signed the Framework Agreement between the Government of Ukraine and the Government of the Republic of India on Cooperation in the Peaceful Uses of Outer Space, which would enter in force on February 15, 2006.[9] As per unconfirmed information obtained by Wikileaks this contract involved the transfer of blueprints for a rocket engine by the Yuzhnoye Design Office.[10][11][12]

According to official press release on March 26, 2013 by Ukrainian Ministry of Economic Development and Trade, development of a rocket engine for Indian launch vehicles initiated in 2006 under a joint Indian-Ukrainian project named “Jasmine”[13][14]

During May and June 2015, ISRO and Roscosmos signed a wide-ranging Memorandum of Understanding for cooperation in space.[15] A. S. Kiran Kumar, Chairman of the Indian Space Research Programme, stated that one of the first benefits would be the availability of Russian test stand for initial testing of the SCE-200, while the Mahendragiri semi-cryogenic test stand is finally commissioned. He also stated that the engine was part of the Rs. 1,800-crore semi-cryogenic launch vehicle programme, which would be capable of placing 6,000 kilograms (13,000 lb) to 10,000 kilograms (22,000 lb) in the GTO.[15][16] This cooperation would only be for facilities use and would have no technology transfers, thus, eliminating the international political risk.[15]
