Who has ever seen a LOX/Kerosene liquid 🚀 engine with a blue plume 💎💎💎💎? Not only does it look spectacular, but it also serves as undeniable proof of the 99%+ combustion efficiency achieved in this test. Enjoy this 3-minute, 20-second test of E-2, a mostly 3D-printed 22k lbf (10 tf) ORSC LOX/Kerosene liquid rocket engine. Nominal pressure: 100 bar; mixture ratio: 2.7. Recorded today at Stennis Space Center, this test also secured the duration record for the test stand. E-2 is now available for sale to launch companies.

E-2 has successfully demonstrated a full mission duty cycle with margin, completing a 201 sec run at our Mojave, CA test site. Multiple 200+ sec test fires have now been completed, proving performance and reliability across engine builds. As the highest performance LOX/kerosene engine in the small launch class, E-2 is designed to maximize your payload capacity and unlock more value from every mission to orbit.

E-2 Thrust Vector Control testing is underway! This test includes frequency sweeps starting at a maximum gimbal angle of ±7 degrees, using hardware from a previous engine revision. After completing additional testing on the component stand, the actuator will be deployed to the test site for its first gimballed test fire.

In a recent hotfire our BE-3U engine reached more than 211,500 lbf thrust. That makes BE-3U the highest thrust-to-weight hydrogen engine in history, at more than 90! Here is the video of that test for your enjoyment.

January’s GS2 performed remarkably during our inaugural New Glenn launch, delivering our payload to orbit with less than 1% deviation from the target. Today, we completed a full duration 15-second hotfire test of the upper stage for our NG-2 mission. This time, we achieved enhanced performance from the BE-3U engine, increasing the maximum thrust from 173,000 lbf to 175,000 lbf per engine, further expanding New Glenn’s capabilities for our customers.

E-2’s first 90-second test fire was a success! It performed at 55% power with a low conservative 1.6 mixture ratio as planned. The hardware appears in perfect condition ready for more tests. This is an exceptional result for a first test article (E-2 SN1). The test was also a key milestone for our US Space Force TACFI contract. We’ve wrapped up this test campaign and will be back in January with an updated injector featuring lower LOX passage pressure drop to allow us to increase the LOX mass flow and in turn reach full thrust and high performance O/F mixture ratio of 2.62. We thank our team and partners for making this possible - especially Stennis Space Center and their team. We would also like to thank the @SpaceForceDoD for their TACFI contract support.

🌕 Tested on Earth. Bound for the Moon. The BE-7 engine for our Blue Moon MK1 lunar lander just completed acceptance testing. Two 290-second tests exposed the engine to its full range of thrust and mixture ratios to verify engine performance. The engine is now off to Florida for integration with MK1.

Haven Demo build and test are complete, and it is now undergoing final integration for launch. Meanwhile, we’re moving toward critical systems testing and continuing to build momentum on Haven-1 flight hardware. Haven-1’s primary structure qualification article has successfully completed its test campaign at our Mojave, CA facility, while the flight structure has been fully welded and is being prepared for pressure testing. Designed, manufactured, and tested in-house in the 🇺🇸.
