Did you even read that comment? Enterprise didn't launch herself, killing a person in the process.
Did you read how the wooden cradle was made as fast and good as possible causing the incident? Because apparently the meme makes no sense aside from taking the general information and making a meme. She's one of the "heaviest ships" and yet her actual weight it's not even that much compared to other beastly ships, almost 2k tons is average. But "haha funny heavy ship" apparently
I do seem to remember a fanfic that implied that shipgirls are able to seamlessly change their weight from human-scale to ship-scale so maybe Formidable has less control over that than normal.
