I didn't thought about the name yet, but I'm going to look for one right away, now that you asked. How about
Bowfin? It's an aggressive ambushing carnivore freshwater fish.
Nice that you think it looks mean, since that's one important point for a combat craft. :)
I've actually modeled it, because the kids at school asked for a quick modeling and UV-in demonstration. But I haven't really nailed the proportions and shape I was going for, so I will remodel it. Or not, if one of the kids make one really good texture for it, since I gave that as an assignment to them.
Also I was playing around with the DSMiner. For me that's the last ship that needs proper fixing/redoing, because it looks very random right now. So I made some blocked sketches.
Funny, you ware thinking about Haber craft today too. :D

And maybe even Tanker version:
