What Does SRB Stand For?

SRB stands for Solid Rocket Booster

The Solid Rocket Booster (SRB) is a type of rocket engine that uses solid propellants to provide thrust during the initial phases of a space launch. SRBs are designed to enhance the lift capability of launch vehicles, enabling them to achieve the necessary velocity and altitude to reach orbit. They are typically attached to the main structure of the rocket and ignite simultaneously at launch, burning until their fuel is expended, after which they are jettisoned. SRBs are known for their simplicity, reliability, and high thrust-to-weight ratio, making them a vital component in various space exploration missions.
