  The Falcon 9 has seen five major revisions: v1.0, v1.1, Full Thrust (also called Block 3 or v1.2), Block 4, and Block 5.
  
  V1.0 flew five successful orbital launches from 2010 to 2013. The much larger V1.1 made its first flight in September 2013. The demonstration mission carried a small 500 kg (1,100 lb) primary payload, the CASSIOPE satellite. Larger payloads followed, starting with the launch of the SES-8 GEO communications satellite. Both v1.0 and v1.1 used expendable launch vehicles (ELVs). The Falcon 9 Full Thrust made its first flight in December 2015. The first stage of the Full Thrust version was reusable. The current version, known as Falcon 9 Block 5, made its first flight in May 2018.
