To date, AR1 has undergone more than 155 staged-combustion tests, built and successfully hot-fire tested additively manufactured components, conducted turbomachinery and valve tests, and began procurements for long-lead items."Our experience and proven track record of delivering highly reliable large liquid rocket engines, like the RS-25 for NASA's Space Launch System and the RS-68 for the Delta IV launch vehicle, protects U.S. national security," said Aerojet Rocketdyne CEO and President Eileen Drake. "We have achieved every milestone in our AR1 schedule to be ready for 2019 – we have in place the production facilities, tools, equipment, supply base and, most importantly, highly skilled employees to manufacture the AR1 engine to meet the national security needs of our nation." The AR1 engine is powered by liquid oxygen and kerosene propellants that use an advanced oxidizer-rich staged combustion cycle to generate 500,000 pounds of thrust. A set of two AR1 engines will generate one million pounds of thrust for the Atlas V launch vehicle. Configurable to multiple launch vehicles, AR1 is also a booster propulsion option for the proposed Vulcan launch system and other launch vehicles in development. The AR1 engine incorporates the latest advances in rocket engine technology, materials science and modern manufacturing techniques to deliver an affordable and reliable booster engine. "We have been investing in the AR1 booster engine to maintain 2019 for the nation," added Drake. "AR1 is the right fit for the problem confronting the United States, which is ending reliance on Russian rocket engines."
