Abstract: The invention relates to a device and a method for feeding a propulsion chamber 5 of a rocket engine 1 with at least with a first propellant. The device comprises at least a first tank 2 for containing said first propellant, a first feed circuit 4 connected to the first tank 2, and a first electric pump 10 within said first tank 2 in order to pump said first propellant through the first feed circuit 4. In the method, the first propellant is pumped through the first feed circuit 4 from the first tank 2 by at least said first electric pump 10 that is immersed in the first propellant within the first tank 2.
