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.

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.
Solid-propellant rockets or solid-fuel rockets have a motor that uses solid propellants, typically a mix of powdered fuel and oxidizer held together by a polymer binder and molded into the shape of a hollow cylinder. The cylinder is ignited from the inside and burns radially outward, with the resulting expanding gases and aerosols escaping out ...
The designation for a specific motor looks like C6-3.In this example, the letter (C) represents the total impulse range of the motor, the number (6) before the dash represents the average thrust in newtons, and the number (3) after the dash represents the delay in seconds from propelling charge burnout to the firing of the ejection charge (a gas generator composition, usually black powder ...
At liftoff, the twin BE-4s generate a combined 1.1 million pounds of thrust. The two strap-on solid-propellant boosters generate another 919,200 pounds of push, providing a total thrust of just ...
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.
The SL-3 motor was also test-fired using improvements based on the two previous firings. It resulted in the largest single motor ever fired on Earth at 5.6 million pounds (26.2 meganewtons) of thrust. Since SL-3 used the same casing design and materials as the previous boosters, the change in thrust was obtained from adding a nozzle to the end.
