Launch Vehicle
Falcon 9 Block 5
Falcon 9 is SpaceX's two-stage, partially reusable orbital rocket and the world's most frequently flown launch vehicle. The current Block 5 variant, flying since May 2018, is optimised for rapid reuse: its first-stage booster lands on drone ships or at the launch site and can fly again with minimal refurbishment. Individual boosters have surpassed 20 flights on a single airframe, fundamentally changing the economics of orbital launch.
