USA-280 (codenamed "Zuma") was a classified United States government satellite that was launched by SpaceX on 8 January 2018, on the 47th flight of the Falcon 9 rocket.[1][4] The National Reconnaissance Office was in charge of the Zuma project,[5] though its purpose has not been disclosed.[2][6] In November 2017, Northrop Grumman stated that the launch "is a monumental responsibility and has taken great care to ensure the most affordable and lowest risk scenario for Zuma."[7] The Wall Street Journal reported that the design was very sensitive to vibration and sudden shocks, and had a development cost approaching US$3.5 billion.[8][9]
Following the launch, unnamed sources stated that the satellite was lost during deployment and re-entered the atmosphere,[10] and independent investigations concluded that the spacecraft likely failed to separate from its payload adapter.[11]
