It's the Kestrel from EV: Nova (which as we all know is the ship that singlehandedly put Krain Industries on the map), with a little bit of red added.

They're pretty shameless! Lots of the ships are pulled from EV: Nova with cosmetic changes (no idea about the legality, I suspect they got permission but I haven't looked into it), and there's a setting that skins the UI to look like EV classic.

The Kestrel in Nova is a copy of the Kestrel from the original EV, which itself was a copy of the Estes 'Corsair' model rocket kit, see: https://blog.eamonnmr.com/2018/02/estes-rockets-and-escape-v...

Isn't it all just based upon Wing Commander?

(Without this bracketed addendum, this would be a troll comment rank 16 mega-trolls)

Actually, he based the gameplay on reading the Elite manual but never actually having played Elite.
