The Solid Boosters are small-sized boosters. These boosters are solid-fueled rocket boosters, meaning once ignited, they can’t be shut down until they run out of fuel (when the fuel empties, they are jettisoned automatically).


  • On the Titan II, the boosters fire for 30 seconds before separating.
  • Those boosters are based on the Space Shuttle SRBs, but smaller.
