“engine is mounted off center”??

Really? What’s the design rationale for that?

The part the engines mount to is called "the thrust dome". This particular SN4 was built to mount three raptors. For the initial static fire tests, and perhaps the first hop, talk is that they're just going to use one raptor engine.

They may mount the other two before the 20 km demonstration flight, but talk is the hop will be done with the single engine - but who really knows. I don't. :)

...

They only need one engine to do the short flight test, and if the rocket crashes they only lose one engine. The engines are more valuable than the rocket bodies used for testing.
