Because I wanted to do something lighter.
So I have this lovely dragon (who I got from a free giveaway the Earth Flight did to welcome new members) named Caldera. He came to me with a very useful battle skill that does a lot of damage, but takes a very long time to save up for. I often find my other dragons having to nurse him along until he can use his big skill. So I’ve started imagining him as an ammunition ship, because in the RMN they all have volcano names anyway (and I could have sworn there was a “Volcano-class”, but if that’s what they are, the wiki doesn’t say so.)
