SpaceX is increasing the thrust of the Raptor engines to 300 tons of thrust. 28 Raptor engines will provide 7500 tons of thrust for the Super Heavy Booster.<\/p>\n
The 15 million pounds of thrust is five times the 3 million pounds of the SLS booster which was tested recently.<\/a><\/p>\n The first stage of the Saturn V had 7,600,000 pounds-force of thrust.<\/A><\/p>\n The Space Shuttle generated a peak thrust of 6,800,000 lbf (30,100 kN).<\/p>\n The Soviet Energia had a liftoff thrust of 7,826,000 lbf (34,810 kN).<\/p> The Raptors will have over 380 seconds of ISP for the vacuum version.<\/p>\n Over time, outer 20 will have ~300 tons of thrust & inner 8 ~210, so roughly 7500 tons total at sea level or 1.5 T\/W for booster+ship<\/p>\n — Elon Musk (@elonmusk) September 1, 2020<\/a><\/p><\/blockquote>\n \n
