It has been over a decade since the BE-4 engine began development. In the time since then, there have been quite a few setbacks along with important milestones. Something you would expect when attempting to create a next-generation rocket engine hoping to power multiple future launch vehicles. All of which has led up to the engine’s most important test yet, Vulcan’s first flight.

Vulcan is a new rocket from United Launch Alliance set to lift off for the first time on May 4th. A deal between ULA and Blue Origin years ago facilitated the addition of BE-4’s engines on the first stage of Vulcan rather than Russian made hardware. Now in the final months leading up to this mission, the BE-4 engines are completing all the final tests and checks necessary.

These two BE-4 engines together generate 550,000 pound force of thrust per engine. After an extensive development and test history, they are almost ready for a historic launch and monumental moment for Blue Origin and its future projects. Here I will go more in-depth into the final BE-4 engine tests, the design of these engines, what to expect in the coming weeks, and more.
