00:00If we think back to the Merlin engines, SpaceX has tripled their thrust over the past 15 years.
00:06From around 35 to about 100 tons. SpaceX managed to increase the Merlin engines thrust to weight
00:15ratio from around 70 to 200. As a reminder, this means the engine delivers 70 to 200 times its own
00:25weight. It's a similar story with Raptor. They now have working models and are producing them in
00:31huge numbers. Meanwhile, the production of a Raptor is said to cost less than 1 million US dollars.
00:38The goal is to push the cost of the engines even further down, toward a quarter of a million US
00:42dollars. Compared to Rocketdyne's F1 engines on the Saturn V, which cost 115 million US dollars each,
00:51and the RS-25 from Aerojet Rocketdyne, which powered the Space Shuttle and the SLS,
00:58and also cost 104 million US dollars. That is insanely cheap.
