Explosive and laser damage need to be at least level15 for this ship to be effective. The only cryogenic plant that NEEDS to be legendary is the one making the explosives. The decider combinator near the pump determines the ships speed. The lower the number, the faster the speed. Please note, this isn't going to get a lot of promethium science, but it's a good starter ship to getting the first 20 to 30 science productivity upgrades.
