Sorry but you need to complete team Frontier before starting team Hawk missions.
Second point, you launched 483 tons in orbit, not 600.
Third point, your launcher can't even perform the mission. I tried myself, though I expected it at first sight to be honest.
Your payload weighs 483 tons, your launcher 1962.6 tons. That's a ratio of nearly 25%, only the most optimized launchers can meet that ratio. But your rocket is just a huge mess of fuel tanks and Titans assembled alltogether, the core runs out of fuel before the boosters, the lowest boosters are attached to the one above because there's no separation between the engine and the fuel tank...

Did you even try to fly this thing? Legally I mean. Well, the fact that you don't show any step of the flight is actually another strong hint that you didn't.
This is the fourth time you are caught cheating! Hell, at that level it should belong to Comedy instead of team Hawk...
