What Does SSUS Stand For?

SSUS stands for Spinning Solid Upper Stage

The Spinning Solid Upper Stage (SSUS) is an advanced propulsion system designed to enhance the performance and efficiency of space launch vehicles. Utilizing a solid rocket motor that rotates during flight, the SSUS generates increased stability and improved thrust-to-weight ratio. This innovative technology enables payloads to reach higher altitudes and achieve greater orbital velocities, making it a critical component for modern space exploration and satellite deployment missions. The SSUS represents a significant advancement in upper stage design, optimizing flight dynamics and mission capabilities.
