to pressurize the LO2 and RG-1 tanks of the Soyuz-2.1v first stage, respectively. The oxygen is supplied from the same LO2 tank in liquid form, while the helium is supplied from separate high pressure bottles (known as the T tank). The engine's development started in 2010 and it is a heavily modified version of the

RD-0110 The RD-0110 (or RO-8 , RD-0108 , RD-461 ) is a rocket engine burning liquid oxygen and kerosene in a gas generator combustion cycle. It has four fixed nozzles and the output of the gas generator is directed to four secondary vernier nozzles to s ...
