	Delta IV Heavy United Launch Alliance January 4, 2007
RS-68 Main Engine Delta IV uses the new Boeing Rocketdyne-built RS-68, the first new American-made liquid hydrogen/liquid oxygen engine, which produces 2,891 kN (650,000 lb) of thrust. This engine is mounted on a CBC first-stage structure, which has been designed for ease of manufacture.
Thirty percent more efficient than conventional liquid oxygen/kerosene engines, the RS-68 is environmentally friendly, producing only steam as a combustion by-product
The second flight-rated Delta 4-Heavy vehicle was erected to vertical position at Space Launch Complex 37 at the Cape Canaveral Air Force Station, FL on January 4, 2007. The United Launch Alliance Delta 4-Heavy rocket will launch the 23rd and final Defense Support Program missile-warning satellite. The largest of the Delta 4 family, the Heavy version features three Common Booster Cores mounted together to form a triple-body rocket. The vehicle will deliver DSP 23 directly into geostationary orbit.
