HUNTSVILLE, Ala. (NASA PR) — NASA has awarded the Booster Production and Operations Contract (BPOC) to Northrop Grumman of Brigham City, Utah, to build boosters for the agency’s Space Launch System (SLS) rocket to support nine SLS flights. Northrop Grumman, the lead booster contractor, has produced booster motors for the first three  Artemis missions and is casting the motors for the fourth lunar mission.

This contract, with a value of $3.19 billion, definitizes a letter contract awarded in June 2020 that authorized Northrop Grumman to order long-lead items and build twin boosters for the next six SLS flights. The period of performance extends through Dec. 31, 2031. This includes production and operations for boosters for Artemis IV-VIII and design, development, test, and evaluation of a booster as part of Booster Obsolescence and Life Extension (BOLE) for Artemis IX.

“This contract award ensures NASA will have the most powerful solid rocket boosters ever built for future Space Launch System rockets for the Artemis missions to the Moon,” said Bruce Tiller, SLS Booster Manager at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “The contract allows NASA to work with Northrop Grumman to not only build the boosters for upcoming missions but also to evolve and improve the boosters for future flights.”

PROMONTORY, Utah (NASA PR) — NASA will broadcast a Space Launch System (SLS) rocket full-scale booster test at 2:40 p.m. EDT Wednesday, Sept. 2, on NASA Television and the agency’s website, followed by a media teleconference.
