In 2016, Russia fell to third place for the number of launch attempts, with U.S. and China — 22 attempts each — overtaking its 19 attempts (of which 18 were successful).
Elon Musk's SpaceX Falcon 9 rocket flew a record 18 missions during the year. United Launch Alliance's (Boeing-Lockheed Martin) joint venture completed eight U.S. government missions this year aboard Atlas and Delta rockets, including five from Cape Canaveral Air Force Station and three from Vandenberg Air Force Base in California. That total was down from 12 last year, and half as many as SpaceX has launched in 2017.
ULA tentatively has a dozen government missions scheduled in 2018.
