List of Falcon 9 first-stage boosters

A Falcon 9 first-stage booster is a reusable rocket booster used on the Falcon 9 and Falcon Heavy orbital launch vehicles manufactured by SpaceX. The manufacture of first-stage booster constitutes about 60% of the launch price of a single Falcon 9 (and three of them over 80% of the launch price of a Falcon Heavy), which led SpaceX to develop a program dedicated to recovery and reuse of these boosters for a significant decrease in launch costs. After multiple attempts, some as early as 2010, at controlling the reentry of the first stage after its separation from the second stage, the first successful controlled landing of a first stage occurred on 22 December 2015, on the first flight of the Full Thrust version. Since then, Falcon 9 first-stage boosters have been landed and recovered 46 times out of 54 attempts, including synchronized recoveries of the side-boosters of the Falcon Heavy test flight, Arabsat-6A, and STP-2 missions. One out of three Falcon Heavy center boosters landed softly but it was severely damaged during transport.

In total 22 recovered boosters were refurbished and subsequently flown a second time, including B1046, B1047, and B1049 which conducted three missions, and B1048 with four missions. SpaceX intentionally limited Block 3 and Block 4 boosters to flying only two missions each,[1][2] but the company expects the Block 5 versions to achieve 10 flights each without major refurbishment.[3]

List of boosters

Block 5

Block 5 is the final iteration of the Falcon 9 and Falcon Heavy boosters. Changes include a stronger heat shield, uprated engines, new carbon composite sections (landing legs, engine sections, raceways, RCS thrusters and interstage), retractable landing legs, titanium grid fins, and other additions that simplify refurbishment. SpaceX claims that a block 5 booster can fly 10 times or more. As of November 2019, no booster has flown more than four times.

Full Thrust and Block 4

Falcon 9 Full Thrust was the first version of the Falcon 9 to successfully land. Changes included a larger fuel tank, uprated engines and superchilled propellant and oxidizer to increase performance. Block 4 was a test version that included new hardware like titanium grid fins later used for Block 5. Flights of both the Full Thrust and Block 4 variants of Falcon 9 were limited to 2 flights only, with a total of 14 second flights of these variants. The boosters were either retired or expended.

v1.0 and v1.1

These boosters were the first 2 major versions of the Falcon 9. Version 1.0 had very basic recovery hardware on the first 2 flights only (parachutes) but because both broke up on re-entry due to aerodynamic forces, SpaceX gave up on parachutes and decided to pursue propulsive landings instead. First came some controlled water landings, then came the attempts on the Droneship "Just Read the Instructions 1". None of these boosters were recovered or survived landing after an orbital launch. Two test devices made several short flights each.

Rockets from the Falcon 9 family have been launched 80 times over 10 years, resulting in 78 full mission successes (97.5%), one partial success (CRS-1 delivered its cargo to the ISS, but a secondary payload was stranded in a lower-than-planned orbit), and one failure (the CRS-7 spacecraft was lost in flight). Additionally, one rocket and its payload Amos-6 were destroyed before launch in preparation for an on-pad static fire test.

The first rocket version Falcon 9 v1.0 was launched five times from June 2010 to March 2013, its successor Falcon 9 v1.1 15 times from September 2013 to January 2016, and the latest upgrade Falcon 9 Full Thrust 57 times from December 2015 to present, 25 of which using a re-flown first stage booster. Falcon Heavy was launched once in February 2018, incorporating two refurbished first stages as side boosters, and then again in April and June 2019, the June flight reusing the side booster from the previous flight. The final "Block 4" booster to be produced was flown in April 2018, and the first Block 5 version in May. While Block 4 boosters were only flown twice and required several months of refurbishment, Block 5 versions are designed to sustain 10 flights with just inspections, possibly on a 24-hour turnover.[3]

The rocket's first-stage boosters have been recovered in 47 of 55 landing attempts (85%).

Booster turnaround time

This chart displays the turnaround time, in months, between two flights of each booster. As of August 2019 the shortest turnaround time was 2 months 11 days (B1045). Boosters that are still likely to be re-used (active fleet) are highlighted in bold and with an asterisk.

  1. Exact assignment of boosters B1004–B1009 is not well documented. Sequential numbering according to Jake Meyer's "SpaceX Data" API.[98]
  2. Full Thrust Boosters B1023 and B1025 were converted to side boosters for the Falcon Heavy test flight of February 2018. This configuration will never fly again, as future Falcon Heavy missions will use a modified variant of Block 5 modules as side boosters.
