Though those 69 tons can get to Mun and hopefully land on it.
Are you trying to tell me you designed a KSP ship that's 6000 tonnes on launch?
Can I see the craft file? Please? Can I? Pretty please? A video, perhaps? A screenshot?

As it turns out, it was actually only a third of the mass. (I fail at reading wiki articles) Time to make a 6000 ton ship!
It would be a most glourious creation to make benefit the people of Kerbalistan!
But man I am disappointed now, though I should've caught on when you mentioned it could not even get 100 tonnes to LKO - Kerbin is so much smaller than Earth that a 6000 tonne rocket would exceed that quite handily (provided it held together). Of course, it was always possible that you just fucked up the design and it was just horribly, Kerbalistani inefficient

How on Earth can this do the pitchover maneuver with so few control surfaces?

I'd suggest going for the lowest possible orbit, actually, it shaves off a lot of fuel, but also means you burn a lot more in atmosphere so that beast might fall apart
I usually launch with a 65km apogee set in the autopilot, then kick it up higher after MECO.

Yeah, my rockets pitchover at about 10 km, most of them before first stage burnout, which means it's a very worrisome moment for me every launch

I had first stage burnout at about 60-70km, lol. Going to add another booster stage, bringing the total mass to about 3,800 tons. When I get home, at least.

Are you trying to deliver a complete base to the mun in one piece? Or a medium city to low orbit?
A minute's thought suggests that the very idea of this is stupid. A more detailed examination raises the possibility that it might be an answer to the question "how could the Germans win the war after the US gets involved?" - Captain Seafort, in a thread proposing a 1942 'D-Day' in Quiberon Bay
That rocket looks like one I tried building out of LEGO as a kid. Looks about as stable too

That looks...well, like it was designed by Top Gear. I hope for your sake it doesn't prove to be "ambitious but rubbish."

On the first launch it started blowing up at nine seconds. I dialed down the thrust from 1000kn to 825kn per engine via the throttle and now it seems to be working fine so far:
Its total thrust is 82.5Mn max, 45.375Mn nominal, from fifty five engines in the first stage.

I think there are plans for Orions at some point in the future. Modders will probably get to it eventually if that doesn't happen.
Also, the superheavy failed. I've made a new, leaner design, which worked perfectly when carrying a full Jumbo 64 fuel tank. Now it keeps exploding with the small solar module that I am trying to launch....

Admiral Valdemar wrote:What does that thing mass and what payload capacity can you get up with it?
The megaheavy (how's that PeZook?) masses at 3671.78 tons at launch, and so far it doesn't get past the first stage without blowing up. That may have just been lag causing computation errors though, since the design itself seems pretty stable, and I had similar problems with previously successful rockets later that night.
Since IIRC .17 KSP slows the simulation down when it can't handle it all.
What is most likely happening is that you are reaching max-q (the moment where forces acting on the rocket peak out) - try throttling down right before it blows up. This is most likely true if the thing always falls apart at the same time.
If it doesn't, then you might try MOAR STRUTS

With the megaheavy that made it last a bit longer. With my new superheavy strangely lower throttle made the solar module lifter actually fall apart sooner. Yet the one with a full jumbo on top is fine....
Imperial, I want to know why you bothered with the crew tank on the recovery mission? You could have just used empty external command chairs attached to the side of the rocket to bring the stranded Kerbal home.
