Specifications
The Rocketdyne J-2 engine is a liquid-fuel cryogenic rocket engine used by NASA on its Saturn IB and Saturn V launch vehicles. Running on cryogenic hydrogen and liquid oxygen, the J-2 produces 1,033.1 kN of trust (vacuum) at an ISP of 421s.
Notes
I made this J2 engine as part of my ongoing Saturn V Replica, and decided to post it.
The engine itself is under 500 parts, including a custom gimbal along with both custom sea level and vacuum plumes.
This engine replica is designed to be realistically scaled in addition to having realistic performance and mass. I put a lot of research into this project to make it as accurate as I can.

Wait… is this a device killer? 505 parts?
@GRIFFINAEROSPACE at least 5 although you will need an expert opinion
@rocketcrazy also i read wome comment and heard that you are buildingan exact replica of saturn V, how many parts will it have?
@GRIFFINAEROSPACE well the final thing will have 6 of these engines
@rocketcrazy my device runs up to 700 parts before game becomes unplayable
@GRIFFINAEROSPACE depends on how good your hardware is I guess
Device killer? İt doest have many parts
@RamenNoodlesXVII im the same rocketcrazy ^w^
@rocketcrazy no worries, I found it. What's your tag in the server? Same as here or different?
@RamenNoodlesXVII sorry i do not
@rocketcrazy ah glad to hear, and do you know where the link for the discord is however
@RamenNoodlesXVII pretty good join the SRC discord for almost daily updates
@rocketcrazy hey man, how's the Sat V going
@ImWorld im making the entire saturn v instead
thx for all the upvotes ik its not much for how long ive been gone but i hope its enough
I dont make rockets to go to space but dang this is pretty cool, those pipe bends are god tier
505 parts for the first engine,
3.7 million parts to finish the build
@Edwards RIP living room run you will be missed
The amount of detail in this is mind-blowing.
Wowza, that’s nifty! 😃
@Hermes01000100 More like melted and mixed
Very nice!
I need to test it after the mobile update
