Two Aerojet Rocketdyne-built engines helped power United Launch Alliance‘s  Delta II rocket that launched a National Oceanic and Atmospheric Administration satellite into space. The RS-27A engine generated 237,000 pounds of thrust to lift the rocket carrying NOAA’s Joint Polar Satellite System-1 and the AJ10-118K upper-stage engine produced 10,000 pounds of thrust to insert the payload into orbit, Aerojet Rocketdyne said Saturday.

Aerojet Rocketdyne has received a $22.7 million contract modification for the development of a reusable oxidizer rich staged combustion cycle booster engine designed to use liquid oxygen baseline propellants. The Defense Department said Wednesday the modification will increase cumulative value of Aerojet Rocketdyne’s contract to $218.4 million. Services under the contract include booster engine design, construction and testing. The company […] More

Aerojet Rocketdyne held a groundbreaking ceremony Tuesday for a new manufacturing facility in Huntsville, Alabama. The 136,000-square-foot Advanced Manufacturing Facility is scheduled to start operations in late 2019 and will support the production of various aerospace platforms as well as additive manufacturing work, Aerojet Rocketdyne said Tuesday. The company will also conduct advanced rocket propulsion research and development activities at the new […] More

Aerojet Rocketdyne has tested an engine for NASA‘s second exploration mission at the space agency’s Stennis Space Center in Mississippi. The RS-25 engine, dubbed as E2063, was fired up for 500 seconds in a move to evaluate the system’s capacity to support the EM-2 exploration mission, Aerojet Rocketdyne said Thursday. RS-25 engines will continuously fire […] More

Aerojet Rocketdyne has developed four engines that will support NASA‘s maiden flight for the Space Launch System. The company said Wednesday that the RS-25 engines are now ready to be integrated on the SLS rocket’s core stage in preparation for the Exploration Mission-1 mission. “These four EM-1 engines have … powered 21 shuttle flights with the […] More

Aerojet Rocketdyne will help the Defense Advanced Research Projects Agency develop and test a propulsion system as part of the Advanced Full Range Engine program that aims to realize reusable hydrocarbon propulsion technologies. AFRE looks to develop a propulsion system that could operate at up to hypersonic speed in an effort to deploy responsive hypersonic aircraft for […] More

Aerojet Rocketdyne will offer propulsion system support to help Boeing conduct technology maturation and risk reduction work for the Ground-Based Strategic Deterrent acquisition program. Aerojet Rocketdyne said Thursday that the GBSD program looks to create a replacement for the U.S. military’s current Minuteman III intercontinental ballistic missile units. Boeing received a potential three-year, $349.1 million contract […] More

Aerojet Rocketdyne will provide propulsion system support to aid Northrop Grumman‘s technology maturation and risk reduction efforts under the U.S. Air Force‘s Ground-Based Strategic Deterrent intercontinentinal ballistic missile program. Sacramento, California-based Aerojet Rocketdyne said Monday it will study propulsion options and develop early designs that meet Northrop’s ICBM configurations. The Air Force awarded a $349.1 million contract […] More

Aerojet Rocketdyne supplied the propulsion systems for United Launch Alliance‘s Atlas V rocket that launched a Boeing-built communications satellite Friday to join NASA‘s Space Network. The Tracking and Data Relay Satellite blasted off from Cape Canaveral Air Force Station in Florida atop Atlas V equipped with six helium pressurization tanks, an RL10C-1 upper-stage engine and 12 Centaur reaction control system […] More

Aerojet Rocketdyne tested the fourth and final RS-25 engine controller needed for NASA’s Space Launch System. The company said Wednesday the testing for the fourth RS-25 controller was done at Stennis Space Center, which follows the third controller test done in July to check engine thrust and mixture ratio precision. The four RS-25 engines are designed to provide above […] More

Expenditures related to research and development work on an Aerojet Rocketdyne-built liquid oxygen/kerosene-based propulsion system have amounted to approximately $228 million as of June 30, Space News reported Monday. Aerojet Rocketdyne is one of the two companies that won “other transaction” agreements from the U.S. Air Force in 2016 to develop the AR1 rocket as an alternative […] More

Aerojet Rocketdyne has tested a third RS-25 engine flight controller the company developed to support the launch of a future NASA heavy-lift rocket. The RS-25 flight controller is designed to monitor the health of a rocket engine using real-time adjustments to combustion pressures, turbopump speeds and other configurations such as engine thrust and propellant mixture […] More
