The turbomachinery assemblies for the first development J-2X engine off the production line are completed and ready for transport to Stennis Space Center where the full engine will be assembled and tested next year. The fuel turbopump assembly, pictured in the background, follows the successful assembly of the oxidizer turbopump. The J-2X engine is a highly efficient and versatile rocket engine and has the ideal thrust and performance characteristics to power the upper stage of a heavy-lift launch vehicle.
