Three booster tanks filled with liquid hydrogen and liquid oxygen propellants supplied by Defense Logistics Agency Energy Aerospace launched a United Launch Alliance Delta IV Heavy rocket from Vandenberg Space Force Base, California, Sept. 24. DLA Energy Aerospace provided 470,000 gallons of liquid hydrogen and liquid oxygen for the first and second stage boosters, and 340 pounds of hypergolic propellants for the second stage booster enabling it to place the NRO satellite into the correct orbit.
