Reaction Motors/Thiokol XLR11

The Engine Specifications
Beginning in 1943, Reaction Motors developed the XLR11 for the XS-1 (later X-1) supersonic research aircraft.  The LR11 used ethyl alcohol and LOX fed to 4 thrust chambers.  Chambers could be ignited separately or in any combination.

The earliest flight I can find for the XLR11 is on the XS-1 in 1946.

The U.S. Navy designation for this engine was the XLR8.
