CE-7.5

CE-7.5 is ISRO's indigenous staged-combustion cryogenic engine for the GSLV Mk II CUS/GS3 upper stage. ISRO specifies liquid oxygen/liquid hydrogen propellants, 75 kN nominal maximum thrust, and an 814 s burn time; the existing GSLV family and GSLV Mk II configurations retain one CE-7.5 in the third stage.

    Note
    ISRO identifies CE-7.5 as India's first cryogenic engine, developed by the Liquid Propulsion Systems Centre for the GSLV Mk II cryogenic upper stage, and specifies staged combustion, LOX/LH2, 75 kN nominal maximum thrust, and 814 s burn time.

    Note
    ISRO's indigenous cryogenic-stage mission page identifies the CUS main engine and steering-engine arrangement and reports 73.55 kN nominal vacuum stage thrust; this contextual stage figure is retained as source context without replacing the CE-7.5 engine's 75 kN field.
