Scroll is using the GVSC Nidaba, also by me, which is based on the other half of that same concept art!
No, this is for... something else.
It's a post-Capella Vasudan science cruiser / research station and not meant for front-line combat. As I mentioned earlier it's going to be substantially larger than the INFR1 Neith, with HP to match.
I could never get the hang of Vasudan engines. Its not too late to change them, I'm just not inspired. Maybe I'll just say the Terrans built them.
