The XLR11, company designation RMI 6000C4, was the first liquid-propellant rocket engine developed in the United States for use in aircraft. It was designed and built by Reaction Motors Inc., and used ethyl alcohol and liquid oxygen as propellants to generate a maximum thrust of 6,000 lbf (27 kN). Each of the four combustion chambers produced 1,500 lbf (6.7 kN) of thrust. The engine was not throttleable but each chamber could be turned on and off individually.
