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.[10][11] 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 Thust) 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 production rate. Each Block 5 booster is designed to fly 10 times with only minor maintenance and up to 100 times with major refurbishment.[12]

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 Block 4 version to be launched, completing the transition to an all-Block 5 fleet.[13][14]

The v1.2 design was constantly improved upon over time, leading to different sub-versions or "Blocks". The initial design, flying on the maiden flight was thus referred to as Block 1. The final design which has largely stayed static since 2018 is the Block 5 variant.
