HUNTSVILLE — Aerojet Rocketdyne has completed the qualification static fire test of the eSR-19, an advanced large solid rocket motor.

The engine will power the  next generation Medium Range Ballistic Missile target to test U.S. missile defense systems.

“I applaud the dedicated efforts by teams across Aerojet Rocketdyne to meet this important milestone,” said Eileen Drake, Aerojet Rocketdyne CEO and president. “Our steadfast workforce and advanced solid rocket motor propulsion remain crucial to helping protect our nation and our allies.”

The motor was designed and fabricated in Aerojet Rocketdyne facilities in Huntsville and cast and cured in Camden, Ark. The eSR-19 motors will be integrated into the target systems by the Coleman Aerospace team in Orlando.

The test was conducted by Air Force Research Laboratory and Aerojet Rocketdyne personnel at Edwards Air Force Base.

The eSR-19 is a redesigned version of the SR-19 that serves as the second stage of the  Minuteman III 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.
