Aerojet Rocketdyne has successfully completed the qualification static fire test of the eSR-19, the advanced large solid rocket motor that will power the Missile Defense Agency’s (MDA) next generation Medium Range Ballistic Missile (MRBM) target used to test nation’s missile defense systems. The successful qualification test, conducted by Air Force Research Laboratory (AFRL) and Aerojet Rocketdyne personnel at AFRL’s test facility at Edwards Air Force Base, California, paves the way for delivery of flight test motors later this year. This recent qualification test was the latest achievement in the evolution of Aerojet Rocketdyne’s legacy Large Solid Rocket Motor (LSRM) capabilities, which have included investments in a talented workforce and new modern LSRM facilities.
“I applaud the dedicated efforts by teams across Aerojet Rocketdyne to meet this important milestone. Our steadfast workforce and advanced solid rocket motor propulsion remain crucial to helping protect our nation and our allies,” said Eileen P. Drake, Aerojet Rocketdyne CEO and president.
The eSR-19 is a redesigned version of the SR-19 that currently serves as the second stage of the nation’s Minuteman III strategic missiles. Featuring a lighter, filament-wound composite case and other performance-enhancing improvements, the eSR-19 will provide the propulsion for both stages of MDA’s air-launched, medium-range target vehicle, developed by Aerojet Rocketdyne subsidiary Coleman Aerospace. The motor was designed and fabricated in Aerojet Rocketdyne facilities in Huntsville, Alabama, and cast and cured in Camden, Arkansas. The eSR-19 motors are later integrated into the target systems by the Coleman Aerospace team in Orlando, Florida.
