A United Launch Alliance Delta IV Heavy satellite technology, contracting with the most MISSION rocket will launch the NROL-44 mission for the cost-efficient industrial suppliers, conducting National Reconnaissance Office (NRO). Liftoff rigorous launch schedules, or providing the will occur from Space Launch Complex-37 at highest-quality products to our customers, the Cape Canaveral Air Force Station, Florida. NRO never loses focus on who they are work- ing to protect: our nation and its citizens. MISSION When the United States needs eyes and ears in critical places where no human can reach – Beginning in 1961 to declassification to the be it over the most rugged terrain or through public in 1992, the NRO has worked tirelessly OVERVIEW the most hostile territory – it turns to the to provide the best reconnaissance support NRO. The NRO is the U.S. government agency possible to the Intelligence Community and tasked with designing, building, launching and Department of Defense. maintaining America’s intelligence satellites. Whether creating the latest innovations in

DELTA IV With three common booster cores, the Heavy is the largest in the Delta IV fleet and is the nation’s proven heavy lifter, delivering high-priority missions for the U.S. Air Force, National Reconnaissance Office and NASA. The Delta IV Heavy also launched NASA’s Orion spacecraft on its historic Exploration Flight Test (EFT-1) Payload Fairing (PLF) in 2014. LAUNCH The PLF is a metallic trisector (three-piece shell), 5-meter diameter fairing. The PLF encapsulates VEHICLE Spacecraft First Launch: Dec. 21, 2004 the spacecraft to protect it from the launch (Generic) Launches to date: 11 environment on ascent. The vehicle’s height, P with the 19.8-m (65-ft) long PLF, is approximately 71.6 m (235 ft).
