Blue Origin Completes the Delivery of Flight Engines to ULA for Vulcan’s Initial Launch

Blue Origin completed its delivery of the first BE-4 shipset for United Launch Alliance (ULA), shipping the engines to ULA’s factory in Decatur, AL after final acceptance testing.

Each BE-4 engine provides 550,000 pounds of thrust and has completed an extensive development program. This state-of-the-art engine will end reliance on Russian engines and power a new generation of U.S. launch vehicles. Dozens of these engines are now in production to support a large and growing demand for civil, commercial, and defense launches.

“We’re excited to see ULA’s Vulcan fly,” said Bob Smith, CEO, Blue Origin. “The BE-4 is a great engine, and we’re proud of Team Blue for achieving this milestone as part of ULA’s team. It’s been a wonderful partnership, and this shipset is the first of many more to come.”

“We are very pleased to receive the first two engines for Vulcan’s inaugural flight,” said Tory Bruno, ULA president and CEO. “Development of this new engine is complete, and the performance of the engine is outstanding. It has been a great team effort working together with our partners at Blue Origin and we can’t wait to see Vulcan fly.”
