This is BE-4.

This is BE-4.

There's a huge amount of time put into this. Lots of anticipation and build-up. I hope it meets the hype. Good luck.

Jeff really made an explosive mark in space exploration history with this.

The BE-4 has turned out to be an excellent engine. As I am typing this Vulcan Centaur has completed it's maiden flight successfully using these engines with no major issues relating to the BE-4 at all.
Good job to everyone at Blue Origin the BE-4 has done the job as expected.
😎👍

Woulda been nice to get some isp and twr numbers. Not like we've been spoiled by SpaceX/Rocketlab in that regard, the old guard like Rocketdyne and Energomash also give those figures.

[AdrianBoyko]

This better be the best, most reliable engine ever built, considering how much time they put into it.

[highpointsights]

the first genuinely positive commentary on the BE-4 so far!!

[PotteryLife]

Yep. Looks good. Again. Looking forward to see New Glenn fly in the next couple years. Maybe.

[BroKenneth]

Congratulations on Successful deployment of your BE-4s today with ULA Vulcan Rocket. ❤

This engine is life changing. It really took my breath away

[acarrillo]

I am a big fan of the Raptor series but it's good to see more engines designed for reuse.

[matthewpeck]

I "hear the rumble and feel the energy" multiples times pretty much every day of the tests SpaceX run 17 miles away from my house in Central Texas. Muliple tests, almost every day, on multiple engine families. That's production. What's holding BO back?

[KsNewSpace]

Thanks for giving us an update! Hope now that the engines are built we soon also get to see some shots of New Glenn development :)

[dabbi]

such a shame bezos wasnt onboard the rocket

[shadbakht]

You've had 20 years!! What's taking you so long? Not even made it to orbit yet. This is embarrassingly slow.

[MayuriK_it]

Looks like an incredible engine. I need to see it fly with New Glenn!

[mattgroening]

Oh wow, this looks great. Jeff’s gonna make an explosive change in space travel with this one

[johnbarrile]

Looks like blue origin is stepping up to the plate!! Good luck guys, space is hard!!

[jason]

Uh oh. He said natural gas is a clean burning fuel! The green weenies aren't going to like that.

They have been doing test fires of these engines (currently the 3, I believe) near where I live - to make sure the stand can handle the 4 engine. I don't think this video will ever be able to depict how powerful and loud these engines are. It's incredible.

I'm at least a couple of miles away and can feel it in my chest when I'm outside. I love it.
