Falcon 9 Block 5 is a partially reusable, human-rated, two-stage-to-orbit, medium-lift launch vehicle designed and manufactured in the United States by SpaceX. It is the fifth major version of the Falcon 9 family and the third version of the Falcon 9 Full Thrust. It is powered by Merlin 1D engines burning rocket-grade kerosene (RP-1) and liquid oxygen (LOX).
The main changes from Block 3 (the original Falcon 9 Full Thrust) to Block 5 are higher-thrust engines and improvements to the landing legs along with numerous other small changes to streamline recovery and re-use of first-stage boosters and increase the production rate. Each Block 5 booster is designed to fly ten times with only minor maintenance between launches and potentially up to 100 times with periodic refurbishment.
In 2018, Block 5 succeeded the transitional Block 4 version. The maiden flight of the Block 5 launched the satellite Bangabandhu-1 on May 11, 2018. The CRS-15 mission on June 29, 2018, was the last to be launched on a Block 4 rocket, completing the transition to an all-Block 5 fleet.
