The BE-4 (Blue Engine 4) [5] is an oxygen-rich, [6] liquefied-methane-fueled, staged-combustion, rocket engine. It is produced by Blue Origin. BE-4 was developed with private and public funding. [7] The engine produces 2,400 kilonewtons (550,000 lbf) of thrust at sea level. [8]

2025年2月4日 · Blue Origin announced today the completion of more than 100 staged-combustion tests in development of the American-made BE-4 engine. The test series achieves a key milestone in engine development, providing measurable performance data in advance of the upcoming Critical Design Review.

BE-4 is the most powerful liquefied natural gas (LNG)-fueled oxygen-rich staged combustion engine ever flown. BE-4 is capable of producing 550,000 lbf (2,450 kN) thrust with deep throttle capability.

2024年5月19日 · All you need to know for now is that the BE-4 combusts its propellants in stages to provide better fuel efficiency. At sea level, the BE-4 can generate 550,000 pounds of thrust force.
