Aerojet Rocketdyne Tests Next Generation Large Solid Rocket Motor, Demonstrates Production Maturity of Modern Facilities

HUNTSVILLE, Ala., Oct. 06, 2022 (GLOBE NEWSWIRE) -- With the recent successful test of a next generation large solid rocket motor called eSR-19, Aerojet Rocketdyne has validated advanced motor technology while demonstrating the production maturity of new and upgraded facilities in Huntsville, Alabama, and Camden, Arkansas.

The recent design verification test of the eSR-19, funded by Aerojet Rocketdyne, highlights the company’s evolution of large solid rocket motors that can function as multiple stages for a variety of defense and space applications.

“Our teams building our next generation large solid rocket motors are incorporating innovative materials and applying efficient manufacturing processes,” said Eileen P. Drake, Aerojet Rocketdyne CEO and president. “We continue to invest in the future – in modern facilities and a highly skilled workforce – to design and produce the advanced technology needed to power defense across multiple domains.”

The eSR-19 motor was designed and fabricated in Huntsville, Alabama, and cast and cured in Camden, Arkansas. The test was conducted by Air Force Research Laboratory (AFRL) and Aerojet Rocketdyne personnel at an AFRL test facility at Edwards Air Force Base, California. AFRL personnel also supported the test with motor logistics and data collection.

The advanced motor improves cost and performance by incorporating a graphite composite case, an affordable advanced nozzle, and high-energy, long-life solid propellant.

Weighing nearly 15,000 pounds and measuring 52 inches in diameter, the eSR-19 is a large solid rocket motor program to upgrade the legacy SR-19 motors originally used in the Minuteman II. This capability demonstration is directly applicable to legacy SR-19 applications, and is a building block for multiple systems under development today.

The recent test of the eSR-19 builds upon last year’s successful test of the eSR-73 demonstration motor, which served as a pathfinder for producing and handling large solid rocket motors at the company’s upgraded Camden facilities.

Aerojet Rocketdyne has produced large solid rocket motors for critical defense and space programs for decades. The company transferred the production to its Camden and Huntsville sites as part of its Competitive Improvement Program, which increased affordability and positioned the company for growth.
