SpaceX's Raptor Engine Vs. Blue Origin's BE-4 - What's The Difference In These Rocket Engines
SMRTR summary
SpaceX's Raptor engine outperforms Blue Origin's BE-4 in most technical specifications, featuring higher chamber pressure (350 bar versus 134 bar), better fuel efficiency with 350-380 seconds specific impulse compared to BE-4's 340 seconds, and longer burn times during testing. However, BE-4 engines have successfully powered real orbital missions while Raptor engines remain largely theoretical despite their superior on-paper performance.
