RS-68 Engine Sets a Record and a Direction for the Future in Space

The Boeing Company set a world record recently when a hot-fire test of the RS-68 rocket engine for Delta IV exceeded more than 650,000 pounds of thrust, greater than any single liquid oxygen/hydrogen engine in history. The record was achieved during the first 100-percent power level test of the RS-68 at the Air Force Research Laboratory, Edwards Air Force Base, Calif.
