The SLS Boosters use solid fuel in-game, which makes it impossible to throttle, or to shut down during flight; though they may be jettisoned at any time. Once ignited, they burn at full power until the fuel is exhausted,then automatically separate from the rocket.
The SLS Solid Boosters differ from the SLS Advanced Boosters by shape and paint scheme, but are the same in Lifting Power and Fuel Capacity.
