Space fans have posted on the web an illustration of how the engine compartment of the huge first stage of the Starship rocket ship is likely to look from below and from the side. SpaceX chief Elon Musk confirmed on Twitter that the diagram “fairly accurately” reflects the real picture.
According to preliminary data, 32 methane “raptors” located in rings of 20 (outer) and nine (inner) units around the three central engines will be responsible for acceleration.
Musk clarified that in fact the middle ring of the engines will be closer to the three central ones than shown in the picture, and all 12 will be able to swing synchronously on the gimbal / thrust washer, adjusting the thrust vector.
According to him, in this configuration, braking when landing is “much better”. He also lamented that laying the many long pipes and wires to the 32 engines is the “hardest part” of the design.

The “bottom” of the Super Heavy, as it was not for the first time noted in the comments, is a bit like the layout of the engines of the Soviet super-heavy rocket N-1, which has been developed since the early 1960s. All four test launches of the N-1 were unsuccessful at the stage of the first stage:
The final version of the reusable Starship spacecraft, together with the Super Heavy stage, will be about 120 m high, 9 m in diameter, with a launch weight of up to 5000 tons. They want to bring the payload up to 150 tons into low-earth orbit. Case material – alloy 304L stainless steel. It is designed for both close (from one point of the Earth to another) and long-distance flights into space, including the Moon and Mars. It is planned that the ship will be able to take on board up to 100 people.
In addition, one of the 3D designers showed how the Starship + Super Heavy bundle will look like on the future Deimos offshore platform. The head of SpaceX specified that such an ocean-going spaceport is already under construction and “will be ready for launches next year.”
