Northrop Grumman Test Fires Stage-One Solid Rocket Motor for Sentinel Missile
06 Mars 2023 - 7:18PM
Northrop Grumman Corporation (NYSE: NOC) conducted its first
full-scale static test fire of the Sentinel stage-one solid rocket
motor at the company’s test facility in Promontory.
This development test will further prove the Sentinel team's
design approach and gain confidence to move to the next stage of
testing. The motor fired for the anticipated duration and met
performance parameters and objectives within expected ranges.
“This static fire highlights the advances we’ve made in digital
engineering and gives us confidence in our ability to translate
that into hardware build and test as we continue to make progress
on the path to flight testing,” said Sarah Willoughby, vice
president, Sentinel, Northrop Grumman. “The results allow us to
validate and anchor our stage-one motor performance before entering
qualification testing and completing system analyses, key to
lowering risk as we mature the Sentinel design and advance towards
critical design review.”
Northrop Grumman also leveraged advanced testing equipment that
allowed for increased data collection to better understand motor
characteristics.
“Our investments in digital design, test and advanced
manufacturing help to ensure we develop this next-generation
missile more affordably and with innovation at its core, delivering
to the Air Force a safe, secure, reliable and flexible capability,”
added Willoughby.
The Sentinel intercontinental ballistic missile weapon system is
the U.S. Air Force’s program to modernize the land-based leg of the
strategic triad, replacing the Minuteman III system that has been
in service for more than half a century.
The Sentinel missile features a three-stage booster, with
Northrop Grumman producing stages one and two. The booster is a new
design, using the latest materials and design technologies to
ultimately improve performance, reliability, safety, and
sustainability.
Northrop Grumman is leading a nationwide team that includes
companies from across the defense, engineering and construction
industries as part of the Sentinel engineering and manufacturing
development contract. Overall, the Sentinel program will involve
over 10,000 people across the U.S. directly working on this vital
national security program. For more information, please visit:
