    Aerojet Rocketdyne announced on May 3, 2017, that it completed a hot-fire test of its preburner for the AR1 rocket engine at NASA's Stennis Space Center in Mississippi. The company’s focus is to have an “American-designed and built” booster system that will replace the Russian-built RD-180 engines that are frequently used to launch U.S. national security, civil, and NASA payloads to orbit.
