The performance shown seems pretty legit to me. I gave it a try, I could escape the Solar system:

That was without payload and by spending all the fuel, but it looks honest.

However that rocket can be optimized. TheStolenInvestigator you use too much engines on your first stage. Have a look:

The main engine alone is enough to lift the rocket.
That's still without payload. With a payload it's barely enough, but by making a few optimizations it's easy to alleviate it. Have a look:

I removed the 2 Hawk engines and the hidden fuel tanks on the first stage, and I replaced the second stage engine by a Frontier, which is way more efficient. I made the second stage longer but that's only to compensate for the hidden fuel tanks that I had to remove. And even with a payload, now the TWR is acceptable.

Now look if I run a test:

That's just before separation, I left 10% of fuel in the first stage:

Then to orbit:

And beyond:

That's with a payload (37.5t), and after having left some fuel in the first stage.

If I burn the 1st stage until the end, here is what I end with:

See? Much better! That rocket can still be optimized. Also, always make a try with your build, if possible with a payload at full capacity. That way you will have an accurate idea about your rocket's real capacity :)

My test was with 15t more payload and you know what a difference that makes :) yeah you never show a cargo rocket's performance unloaded. It's deceptive.

This is what your rocket does with a 50t payload.

WITHOUT reserving fuel for landing.

Imagine you still have that to consider... It may not even make LEO at that rate.

With my suggested changes the apoapsis increased by 730.2km.
That's still nowhere near Moon level.

So no, I don't know how your rocket got a payload outside Earth SOI.
Hey TtTOtW , what's that ?? It looks like a automatic rocket tester. Did you develop it ?

So you made a starship inspired by another starship ? And the original starship is named Elecron, and yours is named Elecro ?
That's quite close... If the name is like your ship, it will be very close to the original one....
Why you don't take a Virgin BP and imagine your own ? Take a piece of paper and draw a new starship of you want to do one. That's how I did my first 0g assembly space station

Well I did StarShot... Inspired by Starship but otherwise completely different. Search "StarShot" here on the forum. You'll love it.

Personally I designed the Fish-n ship from Elon Mollusk:

One of my best design so far :p
