[b]United Launch Alliance Successfully Launches NROL-71 in Support of National Security[/b] A United Launch Alliance (ULA) Delta IV Heavy rocket carrying a critical payload for the National Reconnaissance Office (NRO) denoted NROL-71 lifted off from Space Launch Complex-6 on Jan. 19, 2019 at 11:10 a.m. PST. The mission is in support of our country's national defense. "Congratulations to our team and mission partners for successfully delivering this critical asset to support national security missions," said Gary Wentz, ULA vice president of Government and Commercial Programs, "thank you to the entire team for their perseverance, ongoing dedication and focus on 100% mission success." The Delta IV Heavy is the nation's proven heavy lift launch vehicle, delivering high-priority missions for the National Reconnaissance Office, U.S. Air Force and NASA. With its advanced upper stage, the Delta IV Heavy can take more than 14,000 pounds directly to geosynchronous orbit, as well as a wide variety of complex interplanetary trajectories. The mission launched aboard a Delta IV Heavy, comprised of three common booster cores each powered by an Aerojet Rocketdyne RS-68A liquid hydrogen/liquid oxygen engine producing a combined total of more than 2.1 million pounds of thrust. The second stage was powered by an AR RL10B-2 liquid hydrogen/liquid oxygen engine. NROL-71 is ULA's first launch in 2019 and 132nd successful launch since the company was formed in December 2006.
