What's the best launch trajectory again?

The technical term is "pitchover maneuver", by the way

Thank you! Just checked it, and - this is hilarious!

This test rocket goes to LKO (75km) with only 2850m/s (VAC) without touching any key or SAS (except for circularizing). The Vector is obviously overpowered but I was testing high TWR (6 to 15) rocket in sandbox. To avoid blowing the rocket, I needed to reduce then cut engines even before set the Apo to 75km.

Well, the term is rather very specific to rocket launches. What else did you expect to get?

I forgot fins, they are big part of it. Heatshield is not necessary, if you rotate and detach near 95%. Anyways:

Calculating DV and comparing results is tricky because DV isn't a fixed quantity when atmospheric density is changing.

 I design my booster stage to produce 1,800 m/sec DV for 50% atmosphere Isp and 100% atmosphere thrust. The same stage would appear to produce 1,875 m/sec at vacuum (varies greatly with engine) or 1,725 m/sec at sea level.

Best,
