The RD-0214 (Russian: Ракетный Двигатель-0214 [РД-0214], romanized: Raketnyy Dvigatel-0214, lit. 'Rocket Engine 0214', GRAU index: 8D811) is a vernier thruster rocket engine burning unsymmetrical dimethylhydrazine (UDMH) fuel with dinitrogen tetroxide (N2O4) oxidizer in a gas-generator cycle. It has four nozzles that can each gimbal 45 degrees in plane to provide thrust vectoring control to the RD-0212 propulsion module of Proton rocket's third stage. It is a revised version of the RD-0207 (Russian: РД-0214, GRAU index: 8D67).
