The THK "Pollux" Solid Fuel Booster (also known as an SRB) is a solid rocket booster used to provide a short burst of additional thrust to a rocket. It comes as a single unit. The engine and fuel tank are one single part which means that it isn't possible to increase the burn time for it by adding more fuel tanks.

Product description

The Pollux is an engineers best friend. Is your rocket a little too low thrust to get off the pad efficiently? Put one on. Still not enough? Put on a pair. Try six of them if that's still not enough. Or if you're feeling really craft, you can launch your entire rocket with just these tried and true solid rocket motors.
