Engine Model: RLA-300. Designer: Glushko. Developed in: 1972-1975. Propellants: Lox/Kerosene. Thrust(vac): 3,187.000 kN (716,466 lbf). Chambers: 1. Country: USSR. Status: Design 1974. In 1972 to 1974 Glushko proposed lox/kerosene engines for the RLA series launch vehicles and the UR-700M Mars booster with a lift-off thrust of 300 tonnes per chamber. The UR-700M version would use two chambers for a total thrust of 600 tonnes. Following rejection of the RLA and the adoption of the Energia design, this chamber design was 'down-sized' to 200 tonnes thrust for Energia and Vulkan.
