The last flight of a Block 4 booster was in June 2018. Since then all boosters in the active fleet are Block 5. Booster names are a B followed by a four-digit number. The first Falcon 9 version, v1.0, had boosters B0001 to B0007. All following boosters were numbered sequentially starting at B1001, the number 1 standing for first-stage booster.
A solid rocket booster (SRB) is a solid propellant motor used to provide thrust in spacecraft launches from initial launch through the first ascent. Many launch vehicles, including the Atlas V , [ 1 ] SLS and Space Shuttle , have used SRBs to give launch vehicles much of the thrust required to place the vehicle into orbit.

The Space Shuttle Solid Rocket Booster (SRB) was the first solid-propellant rocket to be used for primary propulsion on a vehicle used for human spaceflight. [1] A pair of them provided 85% of the Space Shuttle's thrust at liftoff and for the first two minutes of ascent.
Those are firing GEM 63XL solid rocket boosters (SRBs), built and supplied to ULA by Northrop Grumman (NYSE: ... Even at the sub-$100 million launch cost that Bruno is projecting for Vulcan, that ...
A first list contains rockets that are operational or have attempted an orbital flight attempt as of 2024; a second list includes all upcoming rockets. For the simple list of all conventional launcher families, see: Comparison of orbital launchers families. For the list of predominantly solid-fueled orbital launch systems, see: Comparison of ...
The Graphite-Epoxy Motor (GEM) is a family of solid rocket boosters developed in the late 1980s and used since 1990. GEM motors are manufactured with carbon-fibre-reinforced polymer casings and a fuel consisting of HTPB-bound ammonium perchlorate composite propellant.
Epsilon's first stage has been the modified SRB-A3 which is the solid-rocket booster of H-IIA. As the H-IIA is to be decommissioned and to be replaced by H3, Epsilon is to be replaced by a new version, named Epsilon S. [21] Major changes of Epsilon S from Epsilon are: [21] The first stage is based on SRB-3, the strap-on solid-rocket booster of H3.
