The launch marked the first flight of an Atlas V rocket in 2018 and the second mission of the year for ULA, a joint venture between the aerospace companies Boeing and Lockheed Martin. A ULA Delta IV rocket launched the classified NROL-47 spy satellite for the National Reconnaissance Office (NRO) on Jan. 12. This is also the 75th launch of the Atlas V rocket and the 125th successful launch since the ULA was formed in December 2006, according to the company. The SBIRS GEO Flight 4 satellite follows the January 2017 launch of its predecessor, SBIRS GEO Flight 3. Two earlier satellites, SBIRS GEO Flights 1 and 2, have been operational in orbit since 2013. The ULA's next launch is the GOES-S mission for the U.S. National Aeronautics and Space Administration and the National Oceanic and Atmospheric Administration on an Atlas V rocket. The launch is scheduled for March 1 from Space Launch Complex 41 at Cape Canaveral Air Force Station.
