In September 2018, ULA announced that it had picked the BE-4 engine from Blue Origin and fueled by liquid oxygen (LOX) and liquid methane (CH 4) to replace the RD-180 on a new first-stage booster. [33] The engine was already in its third year of development, and ULA said it expected the new stage and engine to start flying as soon as 2019. [34]

In January 2016, Blue Origin announced that they intended to begin testing full engines of the BE-4 on ground test stands prior to the end of 2016. [20] Following a factory tour in March 2016, journalist Eric Berger noted that a large part of "Blue Origin's factory has been given over to development of the Blue Engine-4". [9]
Blue Origin Enterprises, L.P. is an American space technology company headquartered in Kent, Washington. The company operates the suborbital New Shepard rocket and the heavy-lift New Glenn rocket. In addition to producing engines for its own rockets, Blue Origin supplies engines for other vehicles, including United Launch Alliance's Vulcan Centaur.
Jeff Bezos' Blue Origin readied the company's powerful New Glenn rocket for its delayed but long-awaited maiden flight early Monday, kicking off a high-stakes bid to compete head-to-head with Elon ...
The BE-3 follows the earliest rocket engine development efforts at Blue Origin in the 2000s. Blue Origin's first engine was a "simple, single-propellant engine" called the BE-1 (Blue Engine 1) which used peroxide propellant and generated only 8.9 kN (2,000 lbf) of thrust, and their second, the BE-2 (Blue Engine 2) which was a bipropellant ...
Most liquid engines use a bipropellant, consisting of two liquid propellants (fuel and oxidizer) which are stored and handled separately before being mixed and burned inside the combustion chamber. Hybrid-propellant rockets use a combination of solid and liquid propellant, typically involving a liquid oxidizer being pumped through a hollow ...
By March 2016, the US Air Force had signed development contracts with AJR and Blue Origin to fund development for both engines. [23] The first Vulcan flight with new engines occurred in January 2024. [24] As of May 25, 2020 (20 years since the first launch of the Atlas LV with RD-180), all 90 launches so far were recognized as successful. [by ...
