HUNTSVILLE, Ala. — They call it the Rocket City for a reason. On Monday, production company Aerojet Rocketdyne announced its plan to build a new rocket engine in Huntsville, which will create 100 new jobs.  
The new engine, the ARI, will serve as a replacement to the Russian-made RD-180. A liquid rocket motor, the ARI is slated to be ready by 2019.
Not only will the project boost the local economy, but it will serve as the latest connection between the Yellowhammer State and the new Trump Administration.
"Our world-class workforce is very excited to rapidly bring the AR1 engine into production – it will support the Trump administration's efforts to make our military strong again," Aerojet Rocketdyne CEO and President Eileen Drake told Al.com. "The AR1 rocket engine is crucial to ensuring America's assured access to space and making U.S. launch vehicles competitive across the globe."
Drake noted that Huntsville is the perfect location for the production of the ARI. "Given the top-tier talent at the University of Alabama in Huntsville's Propulsion Research Center, the exceptional level of rocket engine expertise at NASA's Marshall Space Flight Center and at our teammate, Dynetics, and in the local community, Huntsville is the logical choice to locate the new production work on the AR1 engine," she said.
Huntsville Mayor Tommy Battle was ecstatic about Aerojet Rocketdyne's project and told Yellowhammer that it is merely the latest chapter in the city's long history of aerospace innovation. "With our rich history in the space program, Marshall Space Flight Center's role as NASA's propulsion hub, our smart workforce and active industry base in the R&D sector, Huntsville is ideally suited to manufacture this advanced rocket engine," said Mayor Tommy Battle. "We look forward to seeing production begin in the Rocket City."

Aerojet Rocketdyne : Key Milestone Completed for NASA's Orion Spacecraft to Ensure Astronaut Safety
03/01/2017 | 02:18pm EST

REDMOND, Wash., March 01, 2017 (GLOBE NEWSWIRE) -- Aerojet Rocketdyne, a subsidiary of Aerojet Rocketdyne Holdings, Inc. (NYSE:AJRD), recently completed hot-fire acceptance testing of eight auxiliary engines that will be used on the first flight of NASA's Orion spacecraft with the Space Launch System rocket, slated to launch in 2018.

A photo accompanying this announcement is available at http://www.globenewswire.com/NewsRoom/AttachmentNg/2fb2ecb3-4512-4575-9488-02ae8ace74be

Orion's European Service Module (ESM), which remains connected to the spacecraft throughout the mission until just prior to Orion's re-entry to Earth's atmosphere, provides propulsion, power, temperature control, air, and water for crew members. The European Space Agency (ESA) is providing the ESM to NASA for Orion. Aerojet Rocketdyne is responsible for the ESM's eight auxiliary engines and is assisting Lockheed Martin in the refurbishment of the Orbital Maneuvering Subsystem (OMS) engine that Aerojet Rocketdyne originally manufactured for the Space Shuttle and will now be used as the main propulsion for ESM.

'The design approach that has power and propulsion provided by a separate service module traces back to the Apollo program,' said Aerojet Rocketdyne CEO and President Eileen Drake. 'The auxiliary engines we are delivering to Lockheed Martin and NASA for the European Service Module provide a redundant capability to the OMS engine capability.'

The ESM auxiliary engines are based on the company's R-4D design and work in concert with the main OMS engine. By performing off-pulsing for steering and providing redundant capability for the main engine, the auxiliary engines are critical to ensuring astronaut safety. Each auxiliary engine provides 105 pounds of thrust and is capable of firing more than 7,000 seconds in space. They will be located in four pairs on the outside of the ESM.

Starting more than 40 years ago with the Apollo program, Aerojet Rocketdyne has built more than 700 R-4D engines that have compiled a record of 100 percent mission success. Variants of the R-4D have played critical roles in orbit-raising maneuvers for commercial satellites, as well as assisting NASA in exploring the solar system aboard spacecraft such as Cassini, which investigated Saturn and its moons.

'Successful acceptance testing of the auxiliary engines brings us one step closer to enabling human exploration well beyond low-Earth orbit,' said Mike Hawes, Lockheed Martin Orion vice president and program manager.

In addition to providing propulsion for the ESM, Aerojet Rocketdyne also supplies twelve 160-pound-thrust monopropellant engines for the Orion crew module's reaction control system and the jettison motor that is instrumental in separating the launch abort system from the crew module to keep astronauts safe should a problem arise during launch.

Aerojet Rocketdyne is an innovative company delivering solutions that create value for its customers in the aerospace and defense markets. The company is a world-recognized aerospace and defense leader that provides propulsion and energetics to the space, missile defense and strategic systems, tactical systems and armaments areas, in support of domestic and international markets.
