Space Shuttle Solid Rocket Booster - Construction

Construction

The prime contractor for the SRB motor segments is ATK Launch System's Wasatch Division based in Brigham City, Utah.

United Space Boosters Inc. (USBI), a division of Pratt and Whitney, under United Technologies, was the original SRB prime contractor for SRB assembly, checkout and refurbishment for all non-solid-rocket-motor components and for SRB integration. They were the longest running Prime Contractor for the Space Shuttle that was part of the original launch team. USBI was absorbed by United Space Allianc as the Solid Rocket Booster Element division in 1998 and the USBI division was disbanded at Pratt & Whitney the following year. At its peak, USBI had over 1500 personnel working on the Shuttle Boosters at KSC, FL and Huntsville, AL.
