The challenge is pretty simple. You need to transport a payload of 1 kiloton (1000 tons) into orbit.

Rules:
Multiple launches are allowed
Cheats are allowed for initial construction
Payload must be transported all in one go
No cheats for the actual launch

Payload BP provided for your convince. You can use a different one if you want, as long as it is 1000+ tons.

The first stage burns out in under 45 seconds, but pushes us far beyond the atmosphere. After that, the second stage slowly brings us the rest of the way into orbit.

Ok, I've not tried often to send such big payloads, so here is my entry to the kiloton club:
Screenshot_20200614-142313_Spaceflight Simulator.jpg
This is a 3 stage rocket. 1020 tons of payload, 5433 tons overall.
1st stage: 18 Titan - 7200 tons of thrust. Burn time: 74 seconds; TWR = 1.33; delta-V = 1241 m/s

2nd stage: 33 Frontier - 3300 tons of thrust
Burn time: 93 seconds; TWR = 1.2; delta-V = 1386 m/s

3rd stage: 6 Frontier - 600 tons of thrust
Burn time: 130 seconds; TWR = 0.44; delta-V = 629 m/s

So, lift-off!
Screenshot_20200614-142326_Spaceflight Simulator.jpg

That rocket accelerates quickly and is quite easy to fly despite its weight:

And finally:
Screenshot_20200614-142534_Spaceflight Simulator.jpg Screenshot_20200614-142744_Spaceflight Simulator.jpg

Orbit! But the 3rd stage is still unused :eek:
I thought I would loose a lot of delta-V during the staging phases, because of the time it needs to light all engines, but it wasn't that much in the end (way less than what I experienced in the "Jupiterized" challenge).
Well, let's say I've placed 1359 tons of payload on LEO then.

I tried burning the third stage:
Screenshot_20200614-143251_Spaceflight Simulator.jpg
And I missed the Moon by a few meters per second!
Oh well, my payload weighs 1020 tons, so I can pump out 20 tons of fuel from it, and I will still have sent 1000 tons to the Moon right?

And I crashed 1000 tons on the Moon! Most expensive fireworks ever!

So after I finished my space station, I got so fed up with assembling my fuel rocket that I promised myself that I would never build another rocket that is designed to lift 1000 tons. So I made one that lifts 2000. (2046 to be exact.)

It probably could have made it further, but I wasted time trying to detach the boosters properly.

So who here has seen a SHUTTLE put a kiloton into orbit?

Not bad for a shuttle eh? :D
Meet Discovery ΒΧ Sabre. 1362.79t to orbit. In a plane.

Sup, so I, being the humble person I am, decided to be a good sport and upstage you all. 3kt to orbit.

That moment you realise your rocket isn't quite as advertised and use one engine to circularise the orbit cos you think it's more efficient.

Congratulations. You missed the idea of the challenge, but well done.

That was some fancy flying, you're pretty good.

Anyway, here is (slightly more than) 7 kilotons.

Engines on! Frames per second turns to seconds per frame.

2nd stage in orbit. Barely enough fuel! Could have had more fuel left, but it was hard to fly efficiently with so much lag.

Nice performance, but you used a glitch when finishing to reach orbit. A Titan consumes more than 1t/s and should shut down when used at full power while fuel is transferred, but because of this glitch, it still provides 100% thrust with only 1t/s of fuel consumption:

Total payload was 7354 tons btw
