Nine Engine SpaceX Starship for 50% More Payload to Orbit

Elon Musk says that future Starships – or at least certain Starship variants – are being upgraded with 50% more Raptor engines and stretched propellant tanks. This will increase engines from 6 to 9. SpaceX will also increase fuel to about 300 tons. This will enable a larger Starship and Superheavy to launch 220 tons…
Nine Engine SpaceX Starship for 50% More Payload to Orbit


Elon Musk says that future Starships – or at least certain Starship variants – are being upgraded with 50% more Raptor engines and stretched propellant tanks. This will increase engines from 6 to 9. SpaceX will also increase fuel to about 300 tons. This will enable a larger Starship and Superheavy to launch 220 tons to orbit instead of 150 tons.

On December 17th, the Elon confirmed a tweet from three months ago.

The ship is just begging for three more vacuum engines to be added. Tanks will stretch for more propellant load.

The SpaceX Starship would be stretched about 5-6 meters with larger fuel tanks.

The full refueling of Starship in orbit would drop from 8-9 launches down to 7.

If Elon is right with >300 bar, a 9 engine Ship with 300 t more propellant could target 220 t to 200×200 km / 32°. Good thing: Booster would need less boost back propellant. Obviously, we gotta see if I’m right with my mass estimates. And I’m still not sure about SL Isp. Anyone? pic.twitter.com/vKhXq0nB5a

The first orbital test launch of a SpaceX Super Heavy Starship is likely delayed until March because of FAA regulatory delays.
